These powders can be used in a variety of ways to create sparkles inside the glass or as a mother of pearl luster
on the exterior of the piece. The Mother of Pearl powder can be used in the following ways:
1. Gather clear and roll hot glass in Mother of Pearl powder. Heat piece in glory hole. Excess powder which has not melted
on surface of the glass can be removed by dipping the piece in water or by scraping it off with the flat surface of the jacks. Gather more clear glass. At this point you can create colored sparkles by applying a layer
of transparent color over the initial gathers.
2. If you want a layer of sparkles over a color it is best to case the color in clear before applying the Mother of Pearl powder.
3. Mix Mother of Pearl powder with your glass and apply to the exterior of the piece.
4. Sift Mother of Pearl powders into a carbonized mold to get a pearlescent finish on your sand castings.
Also
it is probably a good idea to sift the powder on some thing other than the marver since it easily becomes airborne and also sticks to metal. We hope this product will add sparkle to your line of glass work
