I’m from Colour de Verre and, as you might guess from the company’s name, we have something to do with pate de verre: We make reusable molds for glass casting. Our molds can either be filled with dry frit or a pate de verre paste. We have tons of project sheets at our website ( http://colourdeverre.com ). The project sheets are free and, if you want to try our molds, here is a voucher for 30% off at our website: 109167448099. It is good till the end of January 2009.
