Glass Design : Fusing Technique : Slumping Technique

The slumping process allows glass to distort, stretch and move under the influence of gravity or mechanical force to take the shape and light relief detail of a supporting mould.


Variation of slumping temperature depends on glass type used and identical glass types do not adhere at slumping temperatures.
Once the slumped glass shape is complete it requires annealing to reduce the stress of cooling to room temperature.

The studio uses moulds made of ceramic shell which can be re-used again for subsequent slumping processes. These moulds are efficient as they have low thermal mass which helps reduce the time to heat and cool the glass material.
