Raku Firing

The Upwey Potters are famed for their performances of firing using the Raku technique.
This page features an explanation of the techniques and some examples of work produced.

There is a chance to try Raku firing with Bill Crumbleholme and Laurence Eastwood
during the Upwey Potters Annual Exhibition as part of Dorset Art Weeks in 2021.
There are morning and afternoon sessions between Sunday 23rd May and Saturday 5th June.
From 10.30am to 1.30pm & from 2pm to 5pm.
A pot can be selected and be taken home after applying glaze and watching the firing.
Booking required - charge £20 for each pot and all other costs.
Visit the event webpage for more information and to book.

Meanwhile there is more information about Raku on the Upwey Potters' old website at this link.

The Recipes we use for the Raku glazes (following the advice of Bath Potters Supplies) are as follows :-

White Crackle.
67% High Alkaline Frit
25% Standard Borax Frit
4% Tin Oxide (Or Zinc Oxide)
4% Bentonite

Turquoise.
As White above plus
5% Copper Carbonate

High Copper Glaze.
80% Soft Borax Frit
10% China Clay
10% Flint
2% Copper Oxide
2% Bentonite

The glazes are mixed up as dry powders and then added to hot water (about 5kg of powder to 5ltrs of water), stirred and left to soak for a few hours and then put through a 80s lawn (seive). After settling take any water off the surface and mix the glaze up, adding back water until the consistancy is correct - about double cream, but the thickness depends on how the glaze is applied, either painted or dipped. Sometimes we add a few ml of Epsom Salts, which helps to keep the glaze fits up in suspension rather than settling out quickly.
