As for the method of blackening candles, it depends on whether it is a partial eclipse or a total solar eclipse. If it is a partial solar eclipse, smoke it until you put your fingers aside and see them from the other side. However, the landlord had better decide according to the specific situation of the day, but I don't recommend this method. Okay, the glass is burnt out. What about the explosion of inferior glass? And the degree of blackening is not easy to control.
