White stoneware is the most useful compromise on a pottery supplier's shelf: it fires hard and vitrified like any stoneware, it comes out white enough for glazes to read true, and it costs a fraction of porcelain while being far easier to use. Most studios keep one smooth and one grogged.
Why white stoneware rather than porcelain
Porcelain is whiter and can be translucent, and it is short, unforgiving and expensive. White stoneware gives most of the visual benefit with none of the difficulty: it centres and pulls like a normal body, tolerates thick sections and long working, and costs around a pound a kilogram at bag quantity rather than several. For functional ware where the glaze does the talking, it is the sensible default.
Smooth and grogged versions of the same body
Suppliers list both, usually under the same name with a G in the code. The grogged version reduces cracking on large or heavily worked pieces and adds a fine texture to the surface; the smooth version throws more finely and takes crisper detail. Buying a bag of each and using them for different work is more useful than trying to pick one.
What it costs
White stoneware sits with the general-purpose bodies at the cheaper end of a price list. The body priced across two suppliers in this index, Draycott White Stoneware, runs about 0.96 to 1.18 pounds per kilogram excluding tax for a 12.5 kg bag depending on where it is bought, with the manufacturer the dearer of the two on the day it was read.
Keeping it white in a shared studio
White bodies show every contamination and iron marks cannot be removed after firing. Separate boards, separate reclaim, washed tools and a wiped wheel head between bodies is the whole discipline. Where a studio runs both white and dark clays, working white first in a session and cleaning down afterwards saves most of the trouble.
Questions people ask about stoneware
Is white stoneware the same as porcelain?
No. Both fire high and white, and porcelain is finer, more translucent, harder to work and considerably more expensive.
Smooth or grogged white stoneware?
Smooth for fine thrown work, grogged for large or hand-built pieces. Most studios keep both because the bodies cost much the same.
What does white stoneware cost?
About 0.96 to 1.18 pounds a kilogram excluding tax for a 12.5 kg bag on the body this index prices at two suppliers, falling sharply with quantity.
