From the section on Fracture Filling: "The filling glass melts at such a low temperature (1673 Kelvin)..." .
1673 Kelvin is 1400 C. Most glasses melt at around 500 C, so something must have gone wrong here. Also, the figure given is implausibly precise for a glass-liquid transition, and degrees K aren't really an appropriate unit. I can't guess what has gone wrong, so I won't try to fix it.

HPHT was developed in the 1960's by the Russians and in use by GE starting in the early 1970's. Why does the article say 1999? — Preceding unsigned comment added by 69.143.33.15 ( talk) 16:49, 25 March 2012 (UTC)
