How do I prevent sharp edges in castings?

a good way to prevent sharp edges in castings is to allow the edges to flow outward rather than scraping downward

Often, sharp edges are a result of the glass scraping down the side of the mold during firing. To minimize sharp spots, set up your glass and mold up so that as the glass softens, it flows out to meet the walls of the mold, rather than scraping down them and getting hung up.
