Liquid precious metals are supplied ready for use. Further thinning is not recommended. The bottle should not be shaken deliberately and it is essential that bottle lips should be clean before pouring.
For most purposes, liquid precious metals are supplied to the correct viscosity, however, this increases on exposure to air, particularly under warm or dry conditions. It is inadvisable to pour out more liquid precious metal than is required for 30 minutes continuous work. This may vary depending on the atmospheric conditions in the decorating shop. When painting moulded surfaces such as figurines, it may be advantageous to allow the liquid precious metal to become rather more viscous than for lining or banding, otherwise it may tend to drain away from protruding areas and collect in the crevices. If through exposure to air, the liquid precious metal becomes too viscous and tacky, its original painting properties may be restored by working in very thoroughly, one or two drops of Lustre Thinners.
Good quality brushes should be used and these are available in various shapes and sizes according to use, either for lining, banding or tracing. Brushes used exclusively for liquid precious metals should be kept separate, clean and free from dust. After use they should be cleaned with Lustre Thinners. To prepare the brush for painting, it should be dipped into the liquid precious metal and worked on a smooth piece of glass or glazed ceramic tile until it is saturated. The brush should then be passed lightly over the surface in order to remove excess liquid precious metal and the hairs brought to a fine point in the case of a lining brush, or to a smooth edge for a banding brush.
Lustres fire at around 740 to 850oC over glazes to give beautiful metallic effects. Always ventilate the kiln carefully to allow fumes to escape. Fire at around 75-100oC/hr and cool slowly to avoid dunting cracks.
These products are ready-to-use and are generally of a gluey, dark brown liquid. Use a smooth brush. The pieces to be decorated must be well cleaned and bone dry. Gold, platinum and some lustres like copper and bronze do not need to be diluted. The brush must neither be too heavily-laden nor too little-laden and the layer applied must be uniform and fine. Too thick a layer causes burning or clouding during the firing. The other lustres can be diluted with an appropriate thinner at more or less 10%. The Mother of Pearl Iris lustre needs to be diluted at 15% at least (it burns more easily than the others if applied in thick layers. Burnt Iris results in a white powder and does not adhere). Precision scales are recommended when diluting in order to maintain the same fluidity and shade of colour.
