How durable is the quartz glass and how does it handle heat?

The manufacturer cites a softening point around 1730°C, which means the glass maintains shape and clarity at the high temperatures generated inside heater enclosures under normal use.

• High softening point for reliable heat tolerance
• Resists discoloration and crazing longer than ordinary glass

• Check alignment and tighten any retaining brackets per your heater's manual
