Detailed explanation of the whole process of making black plaster

The whole process of making black plaster was explained in detail: frying Huang Dan and refining; Dan on fire; Add the powder and coat it with plaster.

1, Huang Dan Refinery.

Stir-fried Huang Dan is also called Guangdan (generally available in larger Chinese medicine shops, the main ingredient of black plaster). Put Huang Dan in a clean iron pan and stir-fry with slow fire until the water in the lead is exhausted and loose. Urgent fire. Stir fry with a shovel.

When refining, put the sesame oil without alkali into a clean pot, boil it with strong fire, and then change it to slow fire. At first, the gas of oil and water will rise linearly, and after a while, it will rise to the pot. If you use bamboo chopsticks to drop oil into cold water, it will become beads and become a hidden worry of oil refining. Sesame oil is sesame oil (pure soybean oil can also be used to reduce costs). If the oil is mixed with alkali, not only will it overflow, but the plaster will not stick.

2, up and down the fire Dan.

At this time, continue to boil the oil with low fire, slowly put the fried Dan into the boiled oil, and use locust tree or wicker. Continue to stir clockwise, the oil will overflow bubbles and smoke. When the smoke is slightly exhausted, use bamboo chopsticks to drop three or four drops of oil on cold water. Don't let the beads come loose, use them to wipe the water. Rub it with dry hands as much as possible, so as not to tire your hands when sticking them.

3. Add medicinal plaster.

The oil is slightly cooled by heating. Powder is slowly added to it. Stir with a wooden stick. When the oil becomes flat. Then add expensive fine powder. I'm anxious to put on the plaster that hasn't cooled yet. Make a ball with bamboo chopsticks and point the center of the cloth with bamboo chopsticks according to the size of the cloth. Spread it clockwise for a week, then the plaster will become a concern; Cotton cloth should be put into the cooked and warm batter, and stirred and kneaded well while it is hot. Put it on a high place to dry. This is the pulp cloth.
