Deep mould to make a voluminous bowl for serving food, presenting fruit or for artwork.
Good shape for a table lamp or chandelier.
To get the full benefit of the mould and its depth, cut the glass to the outer circumference of the mould.
Instead you can also try a square or oval glass shape.
The steep angle of the mould may result in an uneven slumping. Reposition the slumped piece and fire a second time or reposition during slumpng.
