How To Reproduce a Sea Sponge using Liquid Plastic
Step 1: Securing Original Model
Start with an original model. This plastic sea sponge was acquired from a local pet store.
Secure original model to a flat base (melamine board) using a glue gun. This will ensure that the original does not float in the liquid rubber and prevent the liquid rubber from flowing underneath the model.
To contain the liquid mold rubber, the model is surrounded by a clear acrylic tube. Minimum distance between the outer edge of the model and the inside wall of the acrylic tube is at least 0.5' (1 cm).
