How do I identify a celadon glaze?

A celadon glaze ranges from pale sea-green to deep olive, created by iron oxide fired in a reducing atmosphere. It possesses a characteristic depth that resembles polished jade. The surface often displays a subtle network of fine crackles beneath the smooth, glass-like finish, distinguishing it from standard modern green paints.

What is the difference between porcelain and earthenware?

Porcelain is fired at extremely high temperatures using fine kaolin clay, resulting in a dense, non-porous material that rings when struck and is frequently translucent. Earthenware utilises lower-fired clay that remains porous unless fully sealed by an opaque glaze like those seen on historic majolica or cabbage tureens.

How should I display an antique bowl?

Display these pieces on stable, flat surfaces away from direct sunlight to protect delicate enamel overglazes and gold leaf accents from fading over time. Use padded display stands if tilting the vessel to show base markings, ensuring the rim supports no undue weight.

Can I use these bowls for serving food?

Historic ceramic pieces, particularly those with historic glaze compositions or delicate overglaze enamels, are generally best reserved for display rather than daily culinary use. Microscopic fissures in older glazes can absorb liquids and harbour bacteria, making decorative placement the safer choice for preservation.

How do I date a Chinese green bowl?

Dating relies on examining the weight of the clay body, the tone of the celadon glaze, and the style of any carved floral or fish motifs present. Imperial marks on the base provide directional clues, though these must be cross-referenced with the potting style and firing characteristics of the specific era.
