Abstract
A destructible moulded pattern for the lost-wax process of casting metals consists of a mixture of 30 to 85 per cent polyethylene and ozokerite. The mixture may be moulded by injection at high or low pressure or by top casting. In an example a mixture of equal parts of polyethylene (M.W. 30,000), and ozokerite is used.
