Slumping into deep square mold
Posted: Tue Jun 12, 2018 11:01 pm
While most of our molds are B.E., we ended up buying some molds on eBay from someone who is getting out of fusing. This mold was kiln washed but never used.
It is not a BE nor does it appear to be a slumpys as far as I can tell from research. The mold measures 12" at the top and the sides are 45 degrees with the bottom base of the mold being 5-1/2" square. It is fairly thick (7mm) and seems well made. Since there were no holes, I did need to drill 4 vent holes in the bottom corners where glass will touch down last.
Am wanting to slump a 9mm thick piece into this mold so so since the piece is only 9" x 9" it is not dropping the full distance. With that said, the 9" square has to drop 2" to reach the base. I have read on other posts here that slumping into deep square molds you can end up getting a dogbone affect. Would rather not practice on this piece as it is combination of B.E French vanilla, Dense White with Cyan sandwiched in between these two. Here is the schedule I am thinking of using..
200F 1000F :20
150F 1225F 1:30 (monitoring at slump temp)
AFAP 900F 2:00
150F 700F :0
Have very little experience with slumping but have done a lot of research. Most of this research comes from this site and BE site. We do subscribe to their videos as well and these are very helpful in the learning phase.
The kiln I am using is an Evenheat Studio24 (side and top elements) interior dimensions of 22" x 22" x 13" deep.
Any feedback would be much appreciated. Can include pictures if need be.
Thanks
