Product Information
WAREHOUSE DEAL -  Medium Heart Mould 8436

A medium-sized heart mould for frit casting that produces beautiful glass hearts, perfect for gifts and display. Makes a charming paperweight.

The heart in the image was made using Red Transparent Fine Frit 1122.01, but other colours such as Erbium Pink Tint (1821.01) and Aqua Blue Tint (1808.01) would also work very nicely.

Bullseye Code: 8976

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

Dimensions

Makes a heart of approximately 5cm x 4cm and 1.5cm thick.

External mould dimensions are10cmx 9.1cm x 3.1cm.

We recommend a fill weight of 45g, fine frit.

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.
