According to the Hindu alchemists, there are four kinds of the ash (*bhasma*) of mercury, namely black (*kajjali*, p. 61), red (vermilion), white and yellow.¹ The white variety is often spoken of as rasakapūra or camphor of mercury; it is often found to be almost pure calomel and sometimes a mixture in indefinite proportions of calomel and corrosive sublimate.
