Potterycrafts Resin Based Open Medium

Description

Resin based open medium for underglaze and on-glaze painting.Underglaze requires hardening on before glazing. Mix and blend together equal parts (by volume) of powder colour with P4264 medium.Then further adjust to the consistency you require by adding more medium.Cleaning Brushes: Use either P4259 Thinners or P4261 Turpentine for brush cleaning.Tips for on-glaze painting:Cadmium reds and yellow:These warm colours need to be applied more thickly and fired at a slightly lower temperature, to 790C (maximum), with little or no soak. This method is most relevant to P4288 Golden Yellow.Outlines:Outlines for designs can be traced or drawn free hand using a soft pencil or fine marker pen. For a more permanent result, a pale brown or grey on-glaze colour can be used with a fine brush or pen. This can then be fired to give an outline which will not be lost after the first firing.Outlines are best done on ware that has been de-greased with turpentine and dried.Matt colours:On-glaze colours can be matted down with the addition of a matting agent such as zincoxide. This should be mixed at approximately two parts colour to one part matting agent.Metals and lustres:When working with any metals or lustres,we recommend you use a brush dedicated to those products. Do not wash your brush with soap and water, as this may cause faults on your next application. Rinse used brushes in theappropriate essence and then wrap the bristle in aluminium foil. If necessary,soften your brush with essence before working.For details of brushes available from Potterycrafts, please refer to our tools, sponges and brush section.ON-GLAZE COLOURS AVAILABLE FROM POTTERYCRAFTSPotterycrafts on-glaze colours fall into 3 categoriesLEADED – (low sol)based on lead fritsLEADFREE – contains no lead whatsoeverRemember in all cases it is your responsibility to have the finished ware tested by a competent organisation
