Melts at 8000-9000 C. Breaks into POBS at 5 pressure. Lets 75% of photons through. Other 25% are bouncing away. Doesn't conducts electricity, Can be destroyed by BOMB. Resists ACID.
Use: Making destroyable objects that should resist high temperatures.
I'm going to be nooby and say that I like this idea... Why compromise with alloys when you could have something that is more effective and easier to use. edit: I change my mind, glass + NTCT makes a good mixture.
@Darkyhard(View Post) Obsidian melts at almost the same temperature as quartz! Anyway, obsidian is technically a glass as it is an amorphous solid consisting of various minerals with a complex internal structure.
