Watering fish
Start by mixing the "Raysin" casting powder with water to form a smooth, creamy mixture.
You will need around eight tablespoons of casting powder for a complete mold. Pour the mixture into the mold provided.
Tap the filled mold lightly on the table or on a flat surface.
This causes any air bubbles trapped during the pouring process to rise and escape. This also gives the surface of your casting a nice smooth finish.
After about 30 minutes, you can carefully remove the cast fish from the mold. However, leave them to air dry for a further two hours to ensure optimum stability.
If there are any rough edges, you can gently smooth them out with sandpaper .
