Handmade Pottery and Ceramics: Body, Glaze, and Underglaze Painting
A guide to ceramic body, glaze, firing, underglaze painting, and the difference between functional tableware and decorative work.
Handmade pottery and ceramics are often sold under similar names, but a responsible product record should separate body, firing temperature, glaze type, decoration method, and intended use.
Underglaze painting means the motif is applied before the final glaze layer and then sealed under it during firing. This can improve durability, but it does not by itself guarantee that a vessel is food safe or suitable for daily use.
Body and firing
The body may be earthenware, stoneware, porcelain, or a mixed ceramic body. Weight, sound, color at the edge, and thickness can help with basic identification.
Underfiring, hairline cracks, or uneven walls may cause problems in daily use. For functional wares, the listing should clearly state food contact suitability and cleaning guidance.
Glaze and decoration
A glaze should not show peeling, unsafe sharp points, or defects that affect use. Minor variation is normal in handmade work, but functional defects should not be hidden as artistic features.
Underglaze decoration usually lasts better than surface painting, yet the color, firing, and glaze quality still need to be reviewed.
Questions before buying
Is the piece suitable for food? Can it be washed? What is the glaze type? Are cracks, chips, or edge irregularities shown in close images?
For online buying, photos of the back, rim, interior, and scale should appear beside the main beauty image.
