Product Information

Create a beautifully spherical piece with this round-based mould. Rubber pads can be attached to the base of the finished piece if more stability is required, or it can be secured when displayed using Museum Gel.

Bullseye Code: 8738

All our moulds are designed for multiple use and with care should last for many firings.


40cm diameter x 8cm deep.

Please note that all our moulds are hand-made and therefore the dimensions may vary slightly from those shown. Mould manufacturers allow a tolerance of up to 2cm. We strongly recommend cutting the glass to the size measured from the actual mould rather than relying solely on the dimensions shown.
