Venting moulds

Raising the mould from the shelf to provide ways for the air to get out of the mould is as important as providing holes in the mould itself. Often people recommend placing the mould on kiln furniture, but it is very easy to have a number of pieces fibre paper to stack in three places under the edge of the mould to provide space for the air to be expelled from the kiln by the dropping glass. Only a little space is required for the air to escape.
