Manufacturing process of wick: 1. Find clean medical cotton. Find some matches or unopened toothpicks. 3. Wrap a match or toothpick with cotton. Generally speaking, it is covered with three layers of cotton. 4. The cotton at the top of the wick is thinner, and the root of the wick can be thicker. 5. Insert the wick into the butter lamp and put it away. Boil the butter. Buy a new small pot instead of the usual one. 2. Scrape off the hard butter with a special spoon (new) and put it directly into the pot. Don't add water, remember never to add water. 3. After the ghee melts, pour the ghee into the oil lamp that has just inserted the wick. 4. Let the ghee in the oil lamp slowly cool and solidify. All right, it's done. When you want to express your love, take out the butter lamp and light it.
