Glass once it begins to flow fully at 1450 & above will just about stick to anything so a ‘release agent’ of some sort is required. Kiln wash, firing paper, boron spray etc. So its not so much the temperature the mold can withstand its the sticky glass! Even stainless steel molds need release agent & its melting point is 2750.
