In this glass-working technique, a flat, or slightly dished piece of glass is heated slowly in the kiln over a mould, to softening point. The glass gently collapses into the mould over a period of hours. The kiln is then slowly brought back to cold.
Since the glass never melts completely, some surface features such as deep engraving, or staining, are retained to some extent
I have used slumping combined with staining, to produce some large bowls
