I tried the Gaffer casting glass today and it worked very well. This was a new, uncast, un-sandblasted piece that was dipped for 5 minutes in the solution. The surface was smooth and consistant except where it was obvious that we had touched it with our hands.
More info on use with other fusing glasses is on the fusing forum.
