Casting Mold for deeper pattern bars made from sheet glass, stringers, frit etc. To cut the pattern bar into murrine slices, a diamond saw is required. Top quality mold is good for hundreds of firings. Make 3 pattern bars at a time. Molds will come with instructions and suggested firing schedules. Buy them while in stock! We can only get these twice a year. Limited quantities are available. Beautiful artwork can be made by arranging the murrine slices to repetitive patterns or by using one murrine slice a focal component in a piece or for jewelery. To stop the glass from running off the mould during the firing, block the ends of the mold with fire bricks, kiln furniture or fiber paper. Make sure your kiln furniture and mold is kiln washed!
