What is DIVITRIFICATION?
Divitrification is the deterioration process in which heated quartz glass breaks down and crystallizes in a chain reaction at a point of contamination (often oils left over from fingerprints) along with prolonged heating.
The contamination spot acts as a catalyst.
quartz glass divitrifies becoming opaque, hard, crystalline and brittle.
Crystallization starts at the contamination spot and travels through the glass and slowly continues in all directions over time.
The hotter the glass, the faster the crystallization occurs.
