50. Burnt ceruss.) Put powdered ceruss into a deep vessel; set it on the fire, stirring it with a ferula, till it has the colour of sandaracha, (red arsenick). Dioscorides also mentions a toasted or roasted ceruss, but the process is of the same nature, and only stopped, when the ceruss acquires a lemon colour. Dioscorid. lib. v. c. 877.
