greenglazed

Greenglazed is a ceramic glaze category defined by a glossy green surface. It encompasses a range of formulations that yield hues from pale seafoam to deep emerald, all with a glassy finish. The term is used by potters and glaze catalogs to distinguish green glazes from other color families such as blue, brown, or transparent glazes.

Most greenglazed finishes use copper as the primary colorant, sometimes combined with iron or tin to adjust tone and opacity. A standard base includes silica, fluxes (such as feldspar or other lead-free fluxes), and a suitable clay body. Copper-based greens are sensitive to kiln atmosphere: reducing environments typically produce vivid greens, while oxidation can shift toward blue-green or olive.

Applications vary: greenglazed glazes can be transparent over slip to reveal body color or semi-opaque to mute the underlying clay. Layering with a clear glaze can enhance luminosity, while celadon-inspired greens rely on iron interactions. Surface effects such as pooling or gloss variation depend on glaze viscosity, application technique, and firing range.

Historically associated with East Asian celadon ware, green glazes have been adopted by contemporary ceramists worldwide. Today greenglazed finishes are common on functional wares, decorative objects, and sculpture, valued for their tonal versatility and glossy, glass-like aesthetic.
