TAG-42 Sasha’s Oil Slick is a dark amber/purple glass that contains a lot of silver and strikes into lots of colors. Sasha Hess liked this one so much Trautman Art Glass named it for him when they rebatched it! Likes a LOT of heat and oxygen, and gives dark blues and purples. However, you can get nearly any color on this glass with practice. Work this color very hot to burn off the haze to get the best bluish strike. May kiln strike a little too.
