At tack fusing temperatures the layers of glass making up the piece are evident at the edge with two layer bases.
It is possible to conceal the layers at rounded tack fuses with a simple layup. If you cut the top piece 6mm larger than the bottom and place it carefully and evenly over the bottom, the top will form over the bottom, concealing the join of the two layers. This will work at all except sharp tack fusing levels.
What is “sharp” tack fusing please?
ReplyDeleteSharp tack fuse is virtually the same as sintering, sometimes called laminating. The edges are as sharp as when the glass went into the kiln but the long soaks at low temperatures bond the glass pieces together.
