This article clearly states that sand is defined by size, not composition. But then it says "Sand is the principal component in common glass," which implies that sand is composed of a specific material. I am aware that silica is the most common component of sand, but not all sand has silica, and saying simply that "Sand is the principal component in common glass," is not accurate. It needs to be clarified.
I deleted the somewhat silly entry "People, especially children, love to play with sand on a beach or in a sandbox. On beaches they make a mountain, a pit, canals, tunnels, a statue, a building (such as a sand castle), etc." as being not very encyclopedic. Would anyone interested in mountains and buildings (links in sentence) really want to know anything about this (beach play) aspect or vice versa? After all, there is probably no limit to the images one could make out of sand on a beach. But this is a collaborative effort, and one man's silliness is probably another's encyclopedia. I'm not hard-nosed. I suggest delete, but leave that to others to decide / Marshman 23:15, 6 Aug 2003 (UTC)
Grain size says sand is in the range 0.063 - 2 mm. - Patrick 07:57, 14 Aug 2003 (UTC)

Hello my name is bob — Preceding unsigned comment added by 98.237.204.29 ( talk) 23:42, 24 September 2018 (UTC)
Does anyone know how purple/violet/blue sand is formed on otherwise normal yellow-sand beaches? I have been digging the net for one hour and not a clue ...
Sorry Marshie, I swear that every perceptive individuals who walked the beaches of the Baltic and the Black Sea will know the difference between yellow and violet sand (I used the word "purple" because it is more often seen on the net). It is too obvious to miss. In other words, the definition of the problem is sufficient for those "in the know"
I think the example pictures are easy to explain. The beach photos from California are of a dark sand beach. The term "normal yellow" (which has not been defined here) does not apply in any sense. The sand here is the result of the breakdown of the local rocks, shown in the photos. The beach is a dark color, perhaps mostly black, but there may be a red chert or some similar mineral also being contributed. The combination of the reddish or red-brown grains and black grains looks purple under the right conditions. The photo from British Columbia is largely an artifact of the film and lighting conditions. The photo is of a light colored sand taken near sunset (sunrise?) when the sun's rays are filtered through atmospheric conditions that give a purplish coloration to shadows, and in this case, reflective surfaces too. Neither example is really one of purple or violet grains, but of the way the sand looks to the camera (and perhaps the eye): purple, yes - Marshman 02:25, 7 May 2005 (UTC)
In some places, the two kinds of sand mix. The purple sands seems to be washed out from some sediment in the dunes, but then it seems to be laid out in layers on a freshly formed beach (as if lighter than the yellow sand; depositing slowly). Some old fisherman mentioned "potassium permanganate", but that can be completely wrong. Sometimes, if you scratch the purple layer with a foot, it shows to be just 1-3 mm thick exposing wet yellow sand underneath.
Dear Marshman, after reading your reasoning, it seems this sand must come from some older dune deposits. There must be some local people, fishermen, oceanographers, forest inspectors or agriculture experts who will know. While still on vacation, I will do my best to inquire and perhaps zero in on the answer. Milan
I am currently at the Baltic coast. Baltic is tideless (shallow). On close inspection, it is very clear that the sand can take all colors from yellow through pink to purplish via violet to black. The culprits are tiny black grains of some substance that looks like 0.1-0.3 mm graphite flakes. The bigger the dose of the grains, the darker the sand. The grains tend to deposit together, hence the clear yellow-violet separation. I have a snapshot of a clay cliff that seems to "leak" those grains, but I have no place to upload it for you in case you were interested to have a peek (the cliff is rather grim and ugly and it is said to host remnants of WW2, mostly aerial bombs, yet the grains producing violet color are not rust, and definitely not KMnO4 -- although a picture of KMnO4 at Wikipedia looks very similar to those flakes, which are definitely not soluble/reactive). The flakes must have some flat well-polished surfaces because they seem to beautifully reflect light when set at the right angle. Probably a physicist could explain how black&shiny admixture combined with mostly transparent grains produces those beautiful color effects. mc.
What people think of 'normal' coloured sand on beaches results from the quartz grains remaining whilst the other softer rock components (feldspar, mica) being disolved over time. It is possible to have a pure white beach (western Scotland) where there is only quartz with some mica flakes to reflect the sun. These beaches are as a result of the granite breaking down and being washed down river to the shore locally. Elsewhere the beaches may be more yellow in colour. This results from sandstone being broken down. The sandstone was originally formed with a significant iron content. In the Canary Islands, some of the beaches are black from volcanic rocks; others are sands blown from the Sahara. So all gfddhhgsegbnadsdRGSGHGFGYFHGFGHFJHRUYRFUcolours can be found. It all depends upon what rock broke down to form the beach sand. —Preceding unsigned comment added by Mistersumner ( talk • contribs) 19:07, 12 June 2008 (UTC)
The green sand from this beach: Green Sand Beach in South Point, Hawai'i is made from the semi-precious stone called olivine. It's really more like an olive sand beach, but still cool. There is a vein of olivine running through the shore that is being eroded to replanish the frequently-pilfered sand. —Preceding unsigned comment added by 74.182.129.202 ( talk) 22:59, 7 October 2008 (UTC) removed an idiot's comment 86.169.55.51 ( talk) 23:01, 19 February 2009 (UTC)
If somebody can help me on what is the conversion of sand, Cubic Meter to Tonne. The sand is normally used for brick manufacturing, Would it be m3 x 1.29 = ton ? or m3 divided by 1.29 = ton ?
Is't sand used to make glass as well? Is it worth mentioning in the article?
I would like to know about the buoyancy sand causes in the ocean (Such as the Dead Sea).
The hazards of sand use are grossly overstated in this article. I represent an emerging sand conglomerate from Indiana, and we've not experienced, or even heard of, any of the problems this article mentions.
Normal sized sand grains are not particularly hazardous, but applications such as sandblasting, where the abrasion creates tinier particles which can then be breathed, are quite hazardous. This silica dust bonds to lung tissue so firmly that it cannot be exhaled, and cause long-term damage. In the sand blasting field, much of the use of quartz sand has been curtailed for safety reasons, and black sand which is low-silica, ground slag, are instead substituted. Pollinator 04:20, 9 February 2006 (UTC)
The functionality of our corporation is to collect and harvest sand from beaches in southern California, for transport to Hawaiian lava fields, for use in resorts as a beach substitute. The subjects discussed in this article should never encompass the use of silica and so forth. Sandblasting "sand" is not sand at all, but finely engineered pellets. Sandblasting operations are completely unrelated to sand, in the traditional sense. This should be addressed with a disambiguation page or some such mechanism.
My take on this is that no one disagrees with what is being said, but that people might get the wrong impression. Would anyone object to this wording? kotepho 07:50, 9 March 2006 (UTC):
The Pleasures of Soil Watching (page 2 col 2 bottom) delightfully makes grain size tangible by telling what they feel like. "The first three terms -- sand, silt, clay -- stand, respectively, for (1) coarse mineral grains (sand particles are 2 to 0.05 millimeters...) which feel gritty when rubbed between the fingers; (2) medium fine particles (silt grains are 0.05 to 0.002 mm...), which feel like flour; and (3) very fine particles (clay particles are less than 0.002 mm...), which feel sticky when wet." (duplicated from Talk:Grain size)
(This relates to the following question. On page 236 of 'How To Read Water', Tristan Gooley has the first sentence of the first paragraph: "Studies have revealed that each patch of sand in the world is unique, which may go some way to explaining why we have a word for sand collectors - arenophiles - those who are gripped by its endless variety.") — Preceding unsigned comment added by 178.245.238.222 ( talk) 15:01, 30 September 2016 (UTC) Can anyone else verify that the study of sand is called 'arenology'. I can't find the word in any dictionaries and most web uses are derived from Wikipedia. The arenology article here has twice been deleted, original for being an unreferenced hoax / original research. There is some support that the word might not be a neologism at http://www.arenophile.com/ and we still have an arenophile stub. There is also the word 'Arenose', meaning sandy or full of sand, but the only etymology I could find for that, suggested it came from a Latin word 'arenosus' for 'arena sand'. I would have thought that suggests that arenology would more accurately be the study of arenas. -- Solipsist 11:15, 22 September 2006 (UTC)
- Dan ----
Paver sand or "sharp sand" is a course sand that has multi-sized grains. This type of sand is designed to bind together when compressed. Paver sand is used under landscaping pavers for driveways and patios. This will make the joints between the pavers more solid and prevent moisture from getting under the pavers. The problem with using fine "play sand" is that it will wash out easily and not create a locking friction joint between the pavers.
I noticed there is no mention on this page of Biogenic sand. I thought someone might want to add something about it. I was more looking for information on it than anything else though. Here's a link [6]to another site that has a tiny bit of info.
I'm curious to know what the ratio of this biogenic sand is in the world, specifically in the inland deserts rather than coastal beaches or if all that sand comes mostly from erosion. Any info anyone could add to this wiki on the subject would be appreciated. - Arch NME 03:30, 30 November 2006 (UTC)

When dealing with large numbers, people sometimes compare to the total number of grains of sand on Earth. I think it would be useful to have this number mentioned in the sand page. I've done some looking around, but haven't found a standard value used. This guy [7] claims 10^20 to 10^24 grains, but he doesn't say how he got that, and the range is so large as to not be useful. This book [8] calculates about 10^26 grains. With this large of a range I don't feel comfortable adding to the page, but if someone else can find a consistently used value it would be nice to add it. —Preceding unsigned comment added by 128.135.118.171 ( talk) 21:59, 25 May 2009 (UTC)
I have noticed that in large sand deposits, such as sand left by water on beaches and riverbanks, and sand left by wind in sand dunes, the particles seem fairly uniform in size - there is not a wide range of particles as is found in mountain scree slopes. I assume this is due to the fluid mechanics of the deposition process. Perhaps someone could add more to the article about the natural processes that create deposits of sand, and how uniform sized particles are selected for. -- Chetvorno TALK 23:30, 27 July 2009 (UTC)
no mention of sand being used in food and in skin creams and tooth-paste (whiting), sand is in everything! u might be surprised in what products it's being used. Markthemac ( talk) 20:45, 21 November 2009 (UTC)
Why is sand only found at the beach? And why is sand that is inland only associated with either rivers (which may be analogous to the beach, ie, near water) or, paradoxically, in deserts, where there is no water? And how does the process of desertization form the sand? How does the sand appear where there was formerly fertile land? These are the kinds of questions the answers to which I was looking for, but don't appear in this article. Perhaps someone who knows the answers can fill in.

"Sharp sand is a mix of ungraded, coarse sands often with small (sharp) rock chips in it. Good for balast, concreting, and not much else.
Builder's sand is mostly an ungraded product. It is used for a wide variety of purposes, especially in construction (i.e., for ballast, for good drainage when laid under brick paving, or mixing with cement to make morter). Builder's sand may also be mixed with heavy (clay) soils in the garden to improve drainage. Sometimes called "soft" or "orange" sand in the trade, to distinguish from sharp sand.
Masonry sand is a graded variant of builder's sand, rather better for bricklaying and patios. Also called bricklayer's sand.
Silver sand is a mix of graded sand and fine loam; it can be used for bricklaying (light coloured morter), top-dressing lawns, patio concrete and (sometimes) instead of playsand.
Playsand the softest and most graded sand available. The only one really suitable for sandpits."- 169.244.136.38 ( talk) 18:33, 7 September 2011 (UTC)

A question that intrigues is to ponder a comparison of the number of stars in the universe (billions per galaxy, times billions of galaxies) to the size of an area containing an equivalent number of sand particles. A beach, a desert, the entire earth?- the answer would be very approximate of course, but a ballpark image would satisfy the imagination, and could go in the article. Anybody know?

The following quote is misleading
'...The bright white sands found in tropical and subtropical coastal settings are eroded limestone and may contain coral and shell fragments ....'
.
Many very white tropical and subtropical are mostly comprised of quartz. There are some white-ish beaches for which carbonate material makes up a significant portion, but these are not the rule, nor even the norm.
The linked article used as support is clearly 'original conjecture' (no research noted). There are several instances in which the author confuses 'can be found in' for 'is mainly comprised of'. One place is the confusion over the pink beaches in the Bahamas....the red foraminafera which cause the beach to appear pink tinted, only make up a tiny fraction of the total beach material. That foraminafera are present is insufficient to draw conclusions about total composition.
.
White beaches in low energy systems (Gulf of Mexico for instance) are typically rounded clear or white quartz. It is simple to test for carbonates. Addition of vinegar to carbonates will cause off gassing of co2. Most very white beaches don't have much carbonate, so there will be very little off gassing. .

That picture, showing a quarry, has now been replaced by another picture of individual sand grains. That just seems excessive to me, and I reverted accordingly.

It all depends upon what rock broke down to form the beach sand. —Preceding unsigned comment added by Mistersumner ( talk • contribs) 19:07, 12 June 2008 (UTC)
The green sand from this beach: Green Sand Beach in South Point, Hawai'i is made from the semi-precious stone called olivine. It's really more like an olive sand beach, but still cool. There is a vein of olivine running through the shore that is being eroded to replanish the frequently-pilfered sand. —Preceding unsigned comment added by 74.182.129.202 ( talk) 22:59, 7 October 2008 (UTC) removed an idiot's comment 86.169.55.51 ( talk) 23:01, 19 February 2009 (UTC)
If somebody can help me on what is the conversion of sand, Cubic Meter to Tonne. The sand is normally used for brick manufacturing, Would it be m3 x 1.29 = ton ? or m3 divided by 1.29 = ton ?
Is't sand used to make glass as well? Is it worth mentioning in the article?
I would like to know about the buoyancy sand causes in the ocean (Such as the Dead Sea).
The hazards of sand use are grossly overstated in this article. I represent an emerging sand conglomerate from Indiana, and we've not experienced, or even heard of, any of the problems this article mentions.
Normal sized sand grains are not particularly hazardous, but applications such as sandblasting, where the abrasion creates tinier particles which can then be breathed, are quite hazardous. This silica dust bonds to lung tissue so firmly that it cannot be exhaled, and cause long-term damage. In the sand blasting field, much of the use of quartz sand has been curtailed for safety reasons, and black sand which is low-silica, ground slag, are instead substituted. Pollinator 04:20, 9 February 2006 (UTC)
The functionality of our corporation is to collect and harvest sand from beaches in southern California, for transport to Hawaiian lava fields, for use in resorts as a beach substitute. The subjects discussed in this article should never encompass the use of silica and so forth. Sandblasting "sand" is not sand at all, but finely engineered pellets. Sandblasting operations are completely unrelated to sand, in the traditional sense. This should be addressed with a disambiguation page or some such mechanism.
My take on this is that no one disagrees with what is being said, but that people might get the wrong impression. Would anyone object to this wording? kotepho 07:50, 9 March 2006 (UTC):
The Pleasures of Soil Watching (page 2 col 2 bottom) delightfully makes grain size tangible by telling what they feel like. "The first three terms -- sand, silt, clay -- stand, respectively, for (1) coarse mineral grains (sand particles are 2 to 0.05 millimeters...) which feel gritty when rubbed between the fingers; (2) medium fine particles (silt grains are 0.05 to 0.002 mm...), which feel like flour; and (3) very fine particles (clay particles are less than 0.002 mm...), which feel sticky when wet." (duplicated from Talk:Grain size)
(This relates to the following question. On page 236 of 'How To Read Water', Tristan Gooley has the first sentence of the first paragraph: "Studies have revealed that each patch of sand in the world is unique, which may go some way to explaining why we have a word for sand collectors - arenophiles - those who are gripped by its endless variety.") — Preceding unsigned comment added by 178.245.238.222 ( talk) 15:01, 30 September 2016 (UTC) Can anyone else verify that the study of sand is called 'arenology'. I can't find the word in any dictionaries and most web uses are derived from Wikipedia. The arenology article here has twice been deleted, original for being an unreferenced hoax / original research. There is some support that the word might not be a neologism at http://www.arenophile.com/ and we still have an arenophile stub. There is also the word 'Arenose', meaning sandy or full of sand, but the only etymology I could find for that, suggested it came from a Latin word 'arenosus' for 'arena sand'. I would have thought that suggests that arenology would more accurately be the study of arenas. -- Solipsist 11:15, 22 September 2006 (UTC)

Paver sand or "sharp sand" is a course sand that has multi-sized grains. This type of sand is designed to bind together when compressed. Paver sand is used under landscaping pavers for driveways and patios. This will make the joints between the pavers more solid and prevent moisture from getting under the pavers. The problem with using fine "play sand" is that it will wash out easily and not create a locking friction joint between the pavers.
I noticed there is no mention on this page of Biogenic sand. I thought someone might want to add something about it. I was more looking for information on it than anything else though. Here's a link [6]to another site that has a tiny bit of info.
I'm curious to know what the ratio of this biogenic sand is in the world, specifically in the inland deserts rather than coastal beaches or if all that sand comes mostly from erosion. Any info anyone could add to this wiki on the subject would be appreciated. - Arch NME 03:30, 30 November 2006 (UTC)
What are these "fun facts". It speaks nothing of what sand is. I might do as well saying that, "I have a friend who likes sand." The formation of sand should, as has been discussed, be in here.

When dealing with large numbers, people sometimes compare to the total number of grains of sand on Earth. I think it would be useful to have this number mentioned in the sand page. I've done some looking around, but haven't found a standard value used. This guy [7] claims 10^20 to 10^24 grains, but he doesn't say how he got that, and the range is so large as to not be useful. This book [8] calculates about 10^26 grains. With this large of a range I don't feel comfortable adding to the page, but if someone else can find a consistently used value it would be nice to add it. —Preceding unsigned comment added by 128.135.118.171 ( talk) 21:59, 25 May 2009 (UTC)
I have noticed that in large sand deposits, such as sand left by water on beaches and riverbanks, and sand left by wind in sand dunes, the particles seem fairly uniform in size - there is not a wide range of particles as is found in mountain scree slopes. I assume this is due to the fluid mechanics of the deposition process. Perhaps someone could add more to the article about the natural processes that create deposits of sand, and how uniform sized particles are selected for. -- Chetvorno TALK 23:30, 27 July 2009 (UTC)

Why is sand only found at the beach? And why is sand that is inland only associated with either rivers (which may be analogous to the beach, ie, near water) or, paradoxically, in deserts, where there is no water? And how does the process of desertization form the sand? How does the sand appear where there was formerly fertile land? These are the kinds of questions the answers to which I was looking for, but don't appear in this article. Perhaps someone who knows the answers can fill in.

"Sharp sand is a mix of ungraded, coarse sands often with small (sharp) rock chips in it. Good for balast, concreting, and not much else.
Builder's sand is mostly an ungraded product. It is used for a wide variety of purposes, especially in construction (i.e., for ballast, for good drainage when laid under brick paving, or mixing with cement to make morter). Builder's sand may also be mixed with heavy (clay) soils in the garden to improve drainage. Sometimes called "soft" or "orange" sand in the trade, to distinguish from sharp sand.
Masonry sand is a graded variant of builder's sand, rather better for bricklaying and patios. Also called bricklayer's sand.
Silver sand is a mix of graded sand and fine loam; it can be used for bricklaying (light coloured morter), top-dressing lawns, patio concrete and (sometimes) instead of playsand.
Playsand the softest and most graded sand available. The only one really suitable for sandpits."- 169.244.136.38 ( talk) 18:33, 7 September 2011 (UTC)

A question that intrigues is to ponder a comparison of the number of stars in the universe (billions per galaxy, times billions of galaxies) to the size of an area containing an equivalent number of sand particles. A beach, a desert, the entire earth?- the answer would be very approximate of course, but a ballpark image would satisfy the imagination, and could go in the article. Anybody know?

The following quote is misleading
'...The bright white sands found in tropical and subtropical coastal settings are eroded limestone and may contain coral and shell fragments ....'
.
Many very white tropical and subtropical are mostly comprised of quartz. There are some white-ish beaches for which carbonate material makes up a significant portion, but these are not the rule, nor even the norm.
The linked article used as support is clearly 'original conjecture' (no research noted). There are several instances in which the author confuses 'can be found in' for 'is mainly comprised of'. One place is the confusion over the pink beaches in the Bahamas....the red foraminafera which cause the beach to appear pink tinted, only make up a tiny fraction of the total beach material. That foraminafera are present is insufficient to draw conclusions about total composition.
.
White beaches in low energy systems (Gulf of Mexico for instance) are typically rounded clear or white quartz. It is simple to test for carbonates. Addition of vinegar to carbonates will cause off gassing of co2. Most very white beaches don't have much carbonate, so there will be very little off gassing. .

This article clearly states that sand is defined by size, not composition. But then it says "Sand is the principal component in common glass," which implies that sand is composed of a specific material. I am aware that silica is the most common component of sand, but not all sand has silica, and saying simply that "Sand is the principal component in common glass," is not accurate. It needs to be clarified.
Until a recent edit, there were lots of pictures of individual sand grains, but only one that showed something of the extraction of sand. That picture, showing a quarry, has now been replaced by another picture of individual sand grains. That just seems excessive to me, and I reverted accordingly. That edit has now been reverted, so I'm asking for input from others concerning what exactly we should be showing in the images. Mikenorton ( talk) 14:15, 3 October 2018 (UTC)

Before: It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass Suggested edit: Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. 70.50.122.29 ( talk) 23:57, 4 February 2021 (UTC)
