Miscellaneous Materials

Aids in the suspension of glazes. Use solution of Epsom Salts and Water.
Added to powdered glazes it produces a brushing consistency for smooth and even application. Refer to our fact sheet on Glaze Application Techniques for suggested proportions.

Used as a base for a brushing medium to impart green strength to brush work and glaze application. Use at approximately 2% of water content plus an anti-fungicide.

Used to mend cracks in bisqueware. Simply mix to a smooth paste and press into small cracks, smooth over then fire. Fires to a maximum temperature of 1300°C.
Deflocculant used in casting slips. It keeps particles in suspension thereby eliminating the addition of great amounts of water.
The principle of a self-glazing clay was originally developed in ancient Egypt and is now available as Egyptian Paste. It is a self-glazing clay. You need only the powders, a few lengths of nichrome wire, an electric kiln and a little imagination to create a wide variety of beads, buttons, scarabs, charms and a wide assortment of jewellery. Quite simple to work with by adding enough water to the powder to make a paste. Pieces can be formed by rolling on a clean, non-absorbent surface or in the palm of your hand or by hand modelling. To allow for complete glazing, beads and buttons can be dried by being strung on a piece of nichrome wire (the glaze is in the paste and will come to the surface during drying). Fired to Cone 06, the colours are vivid and bright. Stains and oxides can be added for the desired colour effects. Recipes can be supplied upon request or at point of purchase.
For the mending of broken greenware to maximum earthenware temperature of between 1050-1060°C. Apply to both parts to be mended and hold together until firm. When dry fettle away excess.
GUM ACACIA = Gum Arabic
Improves adhesion in glazes, slips and colouring pigments (0.25-0.5%).
Used for painting on to kiln shelves to reduce the risk of pots sticking to the shelves during gloss firing. Mix with water to thick paste and apply evenly up to 1 mm thick. Re-apply as necessary.
A material used on greenware and bisqueware to protect (or mask) an area from colour. Latex can be peeled off prior to firing or to allow for further decoration. Apply one good coat and when finished peel off gently. It will also fire away.
Add to Onglaze powders to create a paste for brushing. Add drop by drop to powder and work with palette knife until desired consistency is reached.
For addition to powdered glaze to bring to brush-on consistency. It can be mixed with powdered glazes, stains, etc. by simply stirring with a cake beater or paint stirrer and running liquid through an 80 mesh sieve. A thicker version of brushing medium. Refer to our Glaze Application Techniques fact sheet for suggested proportions.
PARAFFIN WAX (Granulated – Palm Oil Wax) (BA693)
A granulated wax which, when melted, can be applied to mask and restrict decoration in particular areas. The decorative material is then applied over the entire surface. It will not adhere to the masked areas and the wax resist itself will fire away.
A plasticizer, binder and thickening agent. Added to slip or glaze it will thicken the material for raised designs such as trailing. Please note: Do not add to cadmium selenium glazes. A small amount added to modelling clay or rubbed on the hands aids in retarding the drying rate of the clay as well as making the clay more pliable.
Deflocculant used in casting slips. Care must be taken not to overdose as thickening may occur. It may be used in conjunction with Dispex if required to stabilize flow characteristics.
A high quality potash soap supplied as a liquid. It is used in the production of plaster moulds. Paint on the surface of the mould and wipe away excess with a damp sponge.
An emulsion used to mask areas from decoration. It is the liquid equivalent of paraffin wax.
