Do you glaze pottery before or after firing?

What are the different types of pottery?

The types of Pottery

There are three ba­sic cat­e­gories of pot­tery: earth­en­ware, stoneware and porce­lain. They vary ac­cord­ing to the clay used to make them, and the tem­per­a­ture needed to fire them.

This is the longest-es­tab­lished type of pot­tery, dat­ing back to the Stone Age. Al­though its com­po­si­tion can vary sig­nif­i­cantly, a generic com­po­si­tion of earth­en­ware clay is: 25 per­cent ball clay, 28 per­cent kaolin, 32 per­cent quartz, and 15 per­cent feldspar. It is the soft­est type, be­ing fired at the low­est tem­per­a­ture. It is porous (ab­sorbs wa­ter) and eas­ily scratched.


Called stoneware due to its dense, stone-like character after being fired, this type is impermeable (waterproof) and usually opaque. In its natural state stoneware clay is grey but the firing process turns it light-brown or buff colored, and different hues may then be applied in the form of glazes.


The distinction between porcelain and stoneware is rather vague. Chinese ceramicists define porcelain as any pottery item that gives off a ringing tone when tapped, whereas in the West it is distinguished from stoneware by its characteristic translucence when held to the light. According to the Combined Nomenclature of the European Communities, “Stoneware differs from porcelain because it is more opaque, and normally only partially vitrified.”

What is difference between ceramics and pottery?
With this you will definitely distinguish the difference between the two. Ceramics are not only made by clay but also other materials like glazes, while pottery is made up of only clay. Pottery is a form of ceramics. Ceramics is a broader aspect of molding certain materials into something artistic or something of use.
