Tips for on-glaze painting:
Cadmium reds and yellow:
These warm colours need to be applied morethickly and fired at a
slightly lower temperature, to 790C (maximum), with little or no soak. This method is most relevant to P4288 Golden Yellow.
Transparent colours:
Any on-glaze or glass paint can be madetransparent by the addition of
clear flux.
Products available from Potterycrafts are:
R5925 - Mixing fluxfor low sol colours
R5926 - Mixing flux for low sol colours, suitable for use with cadmium colours
R5625 - Mixing flux for leadless colours
R5930 -Mixing flux for glass colours (high temperature)
R5948 - Mixing flux forglass colours (medium temperature)
These fluxes can also be used as a protective layer over on-glaze
decoration to give extra durability.
Outlines:
Outlines for designs can be traced or drawn freehand using a softpencil
or fine marker pen. For a more permanent result, a pale brown or grey
on-glaze colour can be used witha fine brushor 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 colourscan be matted down with the addition of a matting
agent such as zinc oxide. This should be mixed atapproximatelytwo
parts colour to one part matting agent.
Metals and lustres:
When working with anymetals or lustres, we recommend you use a
brush dedicated to those products. Do not wash your brush with soap and water, as thismay cause faults on your next application. Rinse used
brushes in the appropriate essence and thenwrap the bristlein
aluminium foil. If necessary, soften your brush with essence before
working
