FOR LOTS OF INFORMATION ON RAW MATERIALS, OXIDES ETC..see example below regarding Frits

CALCIUM BORATE FRIT     1030-1180oC. SiO2 17.9%, B2O3 50.3%, MgO 0.1%, Al2O3 4.9%, K2O 0.3%, CaO 26.5%. Insoluble colemanite frit for use where recipes specify greater than 5% colemanite. Can be used as a base in lead free glazes.  

FERRO FRIT 3110     Soft low alumina sodium borosilicate frit for glazes. Often used in crystal and crackle glazes. This frit can be very useful to reduce the feldspar content in glazes (since many high feldspar glazes have low clay content and therefore poor slurry suspension properties and dried hardness). The chemistry of this frit is similar to feldspar (but with low alumina and CaO in addition to the alkali fluxes). That means if you substitute this for at least part of the feldspar you can increase the kaolin (to supply the alumina) and thereby improve slurry properties. In addition you will be able to reduce the amount of troublesome calcium carbonate. Helps in the production of copper blues and manganese purples and raku glazes.  

HIGH ALKALINE FRIT     860 - 1060oC. Typically SiO2 52.5%, B2O3 3.4%, Al2O3 5.2%, Na2O3 18.6%, K2O 10.3%, CaO 2.9%. A high alkaline (Soda and Potash) version of a borax frit. High expansion rate making them suitable for crackle glazes. Helps create turquoise copper blues and purple/brown manganese in glazes.  

LEAD BI-SILICATE FRIT     900 - 1100oC. SiO2 29%, Al2O3 12%, PbO 59%. A good clear, general purpose lead frit for developing rich, bright surfaces and has a good reaction to colours . The safe way to introduce lead. Particularly suitable for red clays.

LEAD SESQUISILICATE FRIT     860 - 1080oC. As above but specially coated to reduce solubility.

STANDARD BORAX FRIT     900 - 1140oC.  Often used in the production of earthenware glazes when a lead-free glaze is required. Slight milkiness, especially at low temperatures, may be evident over red clays, and the colour response with oxides etc is not as vivid as with lead frits.  

All prices are in GBP per kg of material (unless specifically stated) VAT to be added.

ERBIUM OXIDE     Er2O3. Erbium oxide is a light baby pink colour. It is an expensive, dense, and weak colourant, but one of the very few ways you will ever get a transparent pink. Erbium oxide's density means it is absolutely essential that you use CMC gum. Erbium oxide gives its best pink colour at concentrations of 8-10%, but it is difficult to get more than 8% to fully dissolve in the melt. It has given a more lavender colour in the presence of iron traces when in reduction.  

PRASEODYMIUM OXIDE     Pr6O11. Praseodymium Oxide gives a small range of vibrant lime green colours in oxidation and reduction at concentrations of 5-8%. In small amounts (0.65%) in reduction with a trace of iron, gives a bright spring green colour.

Potters Plaster - general purpose potters plaster or plaster of paris

Denstone KD - formerly known as Kaffir Plaster. A very hard plaster. Used mainly in dental laboratories but is often used to make master moulds in pottery.

Dental Plaster - used for working moulds with fine details, also for modelling

Potters Plaster HP2 - Slightly harder than potters plaster, for batts and moulds.

Typical ratio of plaster to water to make a mould: 

Cast Moulds for use with china clay     1.25 kg plaster / 1 litre water

Cast Moulds for use with other clays    1.35 kg plaster / 1 litre water

Handpressed Moulds                                1.4 kg plaster / 1 litre water
