“If you are slumping into a deep mold filled with kilnwash or whatever…..that plugs up the hole in the bottom of the mold for air to escape. What am I missing here? Thank you, Vernelle “
You are slumping at bubble squeeze, or lower, temperatures: the form is relatively shallow: and unless you pack the powder, it will allow some air to disperse through it.
