  • How to pour my jesmonite to avoid air bubbles

Pour a small amount of the mixture into the mould and brush all accessible surfaces with jesmonite. If access is difficult, rotate the mould so that the mixture spreads over the entire surface.

Then fill the rest of the mould.

Make sure you pour the mixture in a thin vein.

Lightly tapping the mould can also help the air to escape.
