Will this mould fit in my kiln?

We strongly recommend using ZYP Boron Nitride Spray with our casting moulds for the very best results. Primo Primer can also be used. Standard shelf primer is not suitable.

When filling the mould, pile the frit in a pyramid or dome shape so the centre of the mould is filled higher than the edges. This helps the correct flow of glass during firing, lowering the risk of the glass 'grabbing' the mould sides as it fires:

See the Small Pod Mould Guide pdf for more details. This schedule is a guideline and you should adjust it to suit your particular kiln, or for different thicknesses of glass:

Phase  Rate (C/hr)  Temp.  Hold (mins)
1 176C 676C 10
2 999 775C 10-20
3 999 515C 30-60
4 30 370C  -

For other shapes, try the Oval Pendant Mould and Cross Pendant Mould.

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. 

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