I have a low fire transparent glaze recipe that makes a nice glossy glaze with a good colour response to various oxides. It has crazed slightly and would be even better for me if that didn't happen.
I know the lead bisilicate helps with the colour response but am not sure about sticking with this as my 'go to' recipe because of the lead.
This is for use on a smooth, white earthenware, sometimes just as a transparent over underglazes or oxide washes, but also as a base with oxide/stain additions.
Can anyone suggest a possible substitute? And if it helps with crazing that would be even better! I know I'll have to re-test, but a starting point would be helpful.
The recipe is -
Lead bisilicate 65
Potash feldspar 15
China clay 10

I am a retired Primary School headteacher. I have set up a home studio and continue to develop my throwing skills. I like to alter, carve and incise my pieces, being more interested in shape, design and form, than colour and glaze finishes. I am currently working in smooth, white earthenware and would eventually love to move on to porcelain once I feel my skill level justifies the cost! I have a small electric kiln with digital controller, which has enabled me to eliminate glaze crazing issues. I have recently tried working in stoneware but am not yet convinced it is better for me than earthenware. I have also begun mixing my own glazes and will be happy once I have just 3 or 4 that are reliable.
