Fighting the Glaze Dragon

Description

At Digitalfire we promote the idea of understanding and formulating your own glazes so you have control rather than relying on suppliers or the trade in glaze recipes.

Software and the Internet

Internet resources for ceramics are growing every day. You can participate in discussions with thousands of people many of whom have years of experience. Check our links page for a springboard into the ceramic internet, use the search field on our home page to search the resources of this site.

Ancient potters prayed to the kiln god to watch over their firings, today they would likely take advantage of available technology.

Abandon Obsolete Thinking

In past we had glaze books filled with cantankerous recipes. Now it is better to have only a few base glazes and adjust these to produce all the needed effects. You should be able to draw a 'family tree' of all your recipes showing how they interrelate and the rationalization for specific alterations.

Good Record-keeping

Determination for Technical Excellence

You might consider The Potters Prayer (see links) if our solutions do not work!

Related Information

The traffic in glaze recipes will burn your success!

They might look great on a fancy website, but what are the chances they will actually work in your circumstances? Very low. After trying many glazes you may think you have found one that works. But does it really? Or is it erratic and unreliable? Difficult to use. Does it leach or craze or shiver or pinhole or blister? Or give you other problems? Be critical and cautious about recipes you find.

Articles G1214M Cone 5-7 20x5 Glossy Base Glaze
This is a base transparent glaze recipe developed for cone 6. It is known as the 20x5 or 20 by 5 recipe. It is a simple 5 material at 20% each mix and it makes a good home base from which to rationalize adjustments.
Articles The Potter's Prayer
A prayer for potters who wish to continue down the road of text book glaze recipes, never really getting what they want, never getting control.
Articles G1947U/G2571A Cone 10/10R Base Matte/Glossy Glazes
These starting recipes use no frits and work in oxidation/reduction and are inexpensive to make. They can be used as bases for the whole range of typical cone 10 pottery glazes (celadon, tenmoku, oatmeal, white matte, brown crystal).
