The Ceramic Manufacturing Guide
How ceramic mugs and tableware are actually made — from clay preparation and glaze chemistry to firing, fettling and quality gates, explained for buyers who need to specify rather than supervise.

Curated from the Storiware knowledge base and organised by the decisions you actually make — specification, sampling, inspection, packaging and freight. New guides are added as the library grows.

Firing, kiln and setting
Whether a piece is fired once or twice before decoration is a process decision with visible consequences — on price, on…
The shelf a piece sits on, the support under its base and the position in the kiln decide more of the finished quality t…
How the manufacturing floor is changing for 2027: automation in forming and glazing, digital kiln control, energy-effici…
How big ceramic buyers understand the firing stage: single-fire vs double-fire, oxidation vs reduction, temperature and…
Decoration and finishing
Seam lines, uneven foot rings and sharp rims are all decided at the finishing station, by hand, with almost no records k…
Most custom ceramic problems are decided before the kiln — in the files and conversations that translate a design intent…
A container of tableware is read by machines and strangers — warehouse scanners, customs officers, stock clerks. This gu…
When a proven design needs a new look, the change is not free and it is not random — each depth of change touches a diff…
