The KPA glaze database is a collection of glaze recipes submitted by members
of the association, visitors, demonstrators at our master-days, and hopefully
other potters from around the world who have visited our web site.
The glazes have been organised into broad categories, based roughly on firing range,
and therefore clay type. Just click on the category which interests you in the column
on the right of this page. As the database grows we may introduce further distinctions
and additional indices.
Each entry gives the suggested firing temperature or range, and sometimes
advice on application or the firing cycle. The submitting potter is credited and
wherever possible the origins of the glaze are stated. An analysis of the glaze
has been made where possible (i.e. if we have an analysis of the component materials)
using the
Glaze Calculator
and the resulting Seger formula (or Unity formula) is shown.
Please remember that glaze materials are variable, so be sure to take the usual
precautions when using a glaze for the first time. (Protecting kiln shelves etc.)
Also be aware of the toxicity of certain glaze materials, both in the raw state, and
in the fired glaze. Any glaze to be used on domestic ware should always be checked
for suitability, and in particular glazes containing lead in any form should be
tested for metal release by a reputable laboratory.
