A method for making shell gold
Grind either skewings or leaf gold with a small amount of clear honey into a paste using a muller and slab. Work the muller slowly in a figure of eight until you have the mixture spread out thinly on the slab, gather up and begin grinding again. Continue this process for approx. 15 minutes or until you have broken down the gold into fine particles. Place the mixture into a glass and fill with hot water to flush out the honey.
When the gold has settled to the bottom of the glass decant the water.
Repeat approx. 5 or 6 times until all the honey is removed. De-ionised or distilled water is recommended for the last 2 stages. Allow the gold pigment to dry. Bind with gum Arabic and store the gold paint in a shell.
All pigments are bound in gum Arabic on W&N watercolour paper.
