Sandcast Glass Design, Process and Art Linda R Fraser ...
Creating the Sandcast Mould . Creating the Sandcast Mould . I have two approaches to making sandcast glass using a sandbox method or a metal tray method. In the sandbox method the sculpture is moulded in a large box of sand. After pouring the glass, the piece is just barely allowed to solidify, then lifted from the sand to be placed in the kiln for annealing.
