Talk:Kyanite/@comment-24863355-20160914023923

Kyanite in real life decomposes into mullite, which is even more heat-resistant, once it reaches 1100 degress farenheit. The same process also makes glass. (more specifically, it creates vitreous silica which is really difficult to melt or otherwise break through high temperatures.)

Since mullite is sturdy enough to make crucibles out of it, I'd like to assume that it's what the Precursors actually use.

That got me thinking: would it be a good idea to use kyanite and mullite in any heat-resistant upgrades for the Seamoth and PRAWN?
