[Preparation method] Put the talcum powder into a flask, seal the bottle mouth, then bury it in a clay pot filled with fine sand, and slowly heat it to sublime. After sublimation is completed, take out the flask, break its upper part, and let it stand. The sublimates will naturally peel off when it cools down a little. Take the sublimate and grind it into powder in a mortar, then rinse it with water and alcohol on filter paper. Finally, warm it slightly and dry it to form a powder cream.

[Chemical composition] This is calomel prepared by the sublimation method, and its composition is mercurous chloride. The Pharmacopoeia stipulates that the content of mercurous chloride in calomel must not be less than 99%. When this product is exposed to light, part of it will turn into highly toxic mercuric chloride and metallic mercury and turn gray (originally colorless), so it must be kept in a sealed and light-proof place.
