PRICE LIST

These are stain based underglaze powders that hold their colour integrity over a wide range of temperatures from 1000oC to 1250oC. These are not just stains, these are stain mixes with silicas and glazes added - the powders are designed to mixed with your water / medium mix for spraying but can be used to create a brush on with extra medium.

Without a top transparent glaze they give a matt surface which we would not consider food safe . As they do contain some glaze they do grab in to the pores of low biscuited clay or greenware but not high biscuited ware where the porosity has been reduced. As often used in school situations we do suggest that you explain to students that the bisque needs wiping down to remove pinholes and salts and to be careful with grease from fingers.

VAT to be added on to all Glaze Prices

Generally if mixing a dipping glaze with Stoneware powders you need a consistency of double cream - start with a ratio of 1 powder to 0.75 liquid and then add more as required mixing well but without trapping air.  Then leave for two hours.

If you are not dipping straight away and it is settling out then next time you can add our UGM medium 75/85% UGM to 15/25% water; or replace 12% of the water with a 2% SCMC cellulose glaze binder solution; or our recommendation is to add 2% bentonite to the dry powder - see Raw Materials.  If creating a brush on we would recommend using the UGM.

These Powdered Underglazes colours have been created from our Glaze Stains - some contain up to 3 different stains, as well as Zirconium Silicate to create a pastel shade.

So if you are trying to achieve these colours in a transparent or white glaze take a look at the stain mixes listed as a guide - we do not guarantee that you will achieve the same colour but it is a starting point.
