Mold Mix 6

Mold Mix 6 is a refractory compound that is used to make molds for casting glass.  It comes in a pre-mixed paste form.  The paste is applied to the surface of a model; after hardening, it can be removed to produce a mold that can be filled with glass and cast.

Mold Mix 6, along with other products in the Luminar line, is made by Zircar Refractory Composites, a company which makes a number of refractory materials for the glass artist.  Molds made from Mold Mix 6 are lightweight, strong, and durable; they're also fairly expensive, but many artists feel their positive features justify the expense.

Mold Mix 6 has several advantages over traditional mold making materials such as plaster/silica.  These include ease of use (no mixing), relative safety (non-carcinogenic), and less of a tendency to crack during firing.  In addition, Mold Mix 6 is far less likely to leave a haze on the surface of the glass after firing.  And finally, because the material is thin and lightweight, it makes molds easier to handle and also reduces annealing time.
