Borosilicate fusing

in 2003 glass alchemy, the eugene glass school and skutt teamed up to work on the "boro fusing project". all of the info from this work can be found in the dec/jan 2003/2004 issue of glassline magazine (Volume17#4). according to this article fusing boro is possible at a temp between 2000 and 2100 degrees for 20 minutes. apparently a fast ramp up and down is most successful and was aided by the use of specially made fast ramping skutt kilns. by ramping from 2000 to 1300 as fast as possible they were able to avoid phase seperation that was otherwise problematic. the most successful surface to fuse on was found to be a kaiser board or a mix of kiln wash and plaster of paris. the article also talks about the results of different color rod and frit tests. __________________
