Glass didn’t slump

I tried slumping for the first time and it didn’t slump into the mold. I have a Paragon Firefly kiln, a two layer (~1/4″) piece of glass (previously fused to make blank) and used the following schedule:
Segment/Rate/Target temp/Hold (obtained from this website)

Too low a temperature for the size of the mould.
Too short a soak (i.e. none) at the top temperature.
Your top temperature is at the low end of slumping temperatures, so you need a long soak. The smaller the mould, the greater the time it takes for the glass to slump – weight and gravity apply. As I don’t know the size of the mould or its shape, nor the size or configuration of your kiln, I can’t really be more specific.
I do have a range of suggestions in my blog, though. use “slumping” for the tag.

Thanks for your reply. I will check out your blogs. For reference, the glass blank is 2″ X 3″ and the mold is the same size rectangle obviously and the depth is about 5/8″. The interior space in the kiln is 8″x8″x4.5″.July 23, 2013 at 7:14 am #13025
