A kiln where heat rises past the pots, causing smudges and tremendous heat loss.

Process where clay grains liquefy and weld together at high temperatures, making pots waterproof.

Early firing method using dung, rarely reaching 800°C and unable to achieve sintering.

Ceramic process involving oxidizing, reducing, and re-oxidizing phases to achieve distinct black and red colours.

Purposefully adding inclusions like flint or mica to clay for specific thermal properties.

The transformation of super-levigated clay slip into a glass-like skin during the reducing phase.

A double-skinned kiln where fire gases never directly touch the pots, preventing smudging.

A kiln that forces hot air downward to maintain uniform high temperatures for sintering.
