How To Reproduce a Sea Sponge using Liquid Plastic

To demold your original, cut the cut the clear acrylic tube and remove it completely. Lift the entire mold to separate it from the base.

Warning: the next step involves cutting with a razor knife, be careful.

Using a razor knife, cut the mold at 12 o' clock, 3 o' clock, 6 o' clock and 9 o' clock. A helping pair of hands can separate the rubber along the cut line and hold it open as you make your cut.

Work the original model out of the rubber mold. Because the original has deep detail and undercuts, it will grab onto the mold. Dragon Skin was chosen as the mold material because it is incredibly strong and stretchy. It will meet the challenge of demolding this original.

The mold has captured all of the surface detail from the sea sponge and is ready for casting.
