Colour de Verre molds must be primed before every use. Hotline Primo Primer (available from Whittemore-Durgin) is one of the primers recommended by Colour de Verre. Firing a Colour de Verre design without first priming it could easily ruin the mold.
Colour de Verre molds should never be heated faster than 350ºF (195ºC) per hour to no more than 1450ºF (785ºC). They should never be filled with float glass, crushed bottles, or borosilicate glass.
