UNIVERSAL MEDIA (WATER)

Universal water based medium, glycerine based open medium. 
Does not need hardening on suitable for underglaze or on-glaze. 


Tips for on-glaze painting: 
Cadmium reds andyellow: These warm coloursneed 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. 

Transparent colours: 
Any on-glaze or glass paint can be made transparent by the addition of clear flux. 
Products available from Potterycrafts are: 
R5925 - Mixing flux forlow 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 for glass 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 soft pencil or fine marker pen. For a more permanent result,a pale brown or grey on-glaze colour can be usedwith afine brush or pen. Thiscan then be firedto give an outline which will not be lost after the first firing. 
Outlines are best done on ware that has been degreased with turpentine and dried.
