This silicone mould is used for casting a coaster holder size ⌀ 105 x 40 mm and two coasters size ⌀ 90 x 10 mm. Coasters will have scalloped edges. This mould is ideal for casting Jesmonite and other creative clays of similar character and can be used repeatedly. Finished casts will make beautiful and functional decorations. To prolong the service life of the mould, we recommend applying a separator to the mould before the start of the casting process.
