"If a quartz crucible vitrifies, it is amorphous and temperature-sensitive.”
We are a member of Ceramic Applications - the meeting place for engineers in design, materials and production technology.
"During the melting process, metal expands more than ceramics and bursts the crucible."
"The heating and cooling curves generally recommended in ceramics for dense components should be observed as far as possible."
