Washed in Industrial methylated spirits (ethanol,methanol) Stabilized by consolidative electrolytic reduction in a 5% aqueous solution of sodium carbonate electrolyte using stainless steel anodes, for 40 hours. The reduced lead was rinsed in tap water then neutralised in dilute sulphuric acid and finally washed in gently running tap water for 4 hours, until the pH of the water remained unchanged. It was dried through Industrial methylated spirits (ethanol, methanol) and gently brushed with a soft glass bristle brush to enhance the legends. Consolidated using 10% Paraloid B72, ethyl methacrylate copolymer, in acetone, applied using brush.
