Here's Slumpy's 6" diameter SM473 Top-Hat Candle mold (retail-$23.99). It posed a bit of a challenge because the sides are vertical and glass doesn't like to fall/slump straight down that easily. Because the drop is about 1.5 inches, the glass will stretch and perhaps thin out too much so we first fused two pieces of SP Spirit glass together giving us a 1/4" thick blank.
We got a perfect result with this schedule-400/hr to 1050- hold 15 minutes
500/hr to 1275- hold 10 minutes.
While the temperature and soak time may be a little higher than the norm, due to the mold shape the glass needed that extra help. We did pick up some back texture from the mold (see pic) but it was minimal as we used a mouth atomizer to apply our kiln wash...
