(54) Flash dressing for use in foundry practice


(57) This invention relates to flash dressing compositions for use in foundries comprising a mixture of diacetone alcohol and a C1,-C4 monohydric alcohol. These mixtures have a flash point above 90°F which meets the safety requirements against fire hazards. In spite of this they are not difficult to ignite or burn-off completely from the castings on which they are applied. They are also less expensive than dressings commercially available hitherto.
