Acid; acidic oxides
In pottery, acids are used in slips and glazes.

In chemistry it is a compound usually having a sour taste and capable of neutralizing alkalis and reddening blue litmus paper, also containing hydrogen that can be replaced by a metal or an electropositive group to form a salt, or containing an atom that can accept a pair of electrons from a base. Acids are proton donors that yield hydronium ions in water solutions, or electron-pair acceptors that combine with electron-pair donors or bases.
