After adding all the liquid string colors for the details, I
let the frit dry (this may take a few hours or a day). Once dry I filled the
rest of the mold with spring green frit (you can use scrap pieces of sheet
glass as well). Unlike the hemisphere paperweight mold, I don't pile this
mold up high as I find the piece is too thick. You can control the
thickness by not filling too high.
Once FULLY dry and filled you are ready to fire your piece.
Fire you kiln at 500 degrees per hour to 1000 and then full speed to full
fuse temp (my kilns range from 1350 - 1540 for full fuse depending on the
size/make of the kiln). Once at full fuse hold for 30 minutes (or
until the 'top' is smooth and flat). Let cool to room temperature before
removing from kiln.
Turn the mold over; your piece may pop right out. If
it doesn't then gently tap the bottom and it should come out with no
problem. NOW you probably have kiln wash on the piece and there may be
some sharp bit on the edges.
Use a sickle stone, sandpaper or metal file to remove the
sharp bits. Wear safety glasses. You can also grind the edges but then
you'll have to decide if you want to fire polish or live with a few marks.
(see fire polishing info on hemisphere paperweight project)
Once the piece is REALLY cool, drop it into a container of
water and let it soak for a few minutes. I usually then run it under the
water in the sink and use a soft brush to remove the kiln wash stuck in the
Voila! You are finished. Now what are you going to do
with this lovely hunk of glass?
