Inevitably
glass will drip down the sides of the crucible. When molten glass
comes in contact with the kiln fire brick, it will slowly eat
away the brick. Even coating the bottom of the kiln with kiln
wash or covering with fiber paper will not help much. A good
way to protect the bottom of the kiln is by placing as large
as possible kiln shelf underneath the crucible to catch the flowing
glass or better yet, set the smaller sized crucible on top of
a crucible catch dish shown in the picture (listed above).
It can take the high temperatures you will be firing to. The
two will "bond" together with the dripped glass, which
is OK. Eventually all crucibles break and if it is full, it will
flood the bottom of the kiln and you will have to replace the
bottom bricks. Unfortunately this is just normal maintenance
for crucible kilns.
To Calculate how many pounds of glass a container holds, multiply 5 times the number of liquid quarts.
Soda/Lime glass weighs 150 pounds per cubic foot.
