Bowl of Sulfuric Acid is an ingredient used to craft a Daniell Cell.
Find a piece of Niter in the Desert and add to a Bowl of Water. Use this niter solution on Ashes, then add a piece of Blank Paper. Use on another Clay Bowl and discard the Dirty Filter Paper. After 30 seconds, the solution will turn into Saltpeter. Combine this with a Bowl of Sulfur, and add to Hot Coals. Within 30 seconds, you must use a bowl of water to extinguish the coals, or the ingredients will be lost. You can then take the Bowl of Sulfuric Acid.
