How to make alum
Where alum is made, use bauxite as the main thing. First take pure soil, put it in a large kettle, soak it in water, stir it well. When it precipitates, take its supernatant liquid, which contains aluminum.
Then, prepare an urn and add an appropriate amount of sulfuric acid. Those with sulfuric acid are strong and good. Pour the aluminum-containing liquid slowly into the urn containing sulfuric acid, and stir it slowly with a wooden spoon. The two are combined, and the state is like boiling, and the smoke is slightly rising. This is a chemical change.
Wait for the reaction to slow down a little, and let it stand for a long time. Then, move the mixed liquid to a shallow pool and simmer slowly. In the meantime, the water vapor gradually dissipates and the alum is gradually thickened. Boil to the right time, and you can see that alum crystals are gradually precipitating out of the liquid.
Scoop the liquid containing crystals into a fine sieve and drain the excess liquid. The resulting alum crystals are white and clear, which is called aluminum alum. With precise method, you can get 1M Solution Aluminum Sulfate. This liquid is of great benefit to many uses, either adding color to the dyeing workshop or purifying water. Its wonders are countless.
