Etymology
The word 'overglaze' is a transparent English compound formed from the native Germanic adverb/preposition 'over' and the noun/verb 'glaze', which itself originates from the concept of 'glass'. In ceramics, a glaze is a glass-like coating fused to pottery. The prefix 'over-' directly indicates the application of a secondary, decorative layer on top of an existing, primary glaze. This compound term logically and literally describes the technical process and the resulting layer, maintaining a clear semantic link from its constituent parts to its specialized artistic meaning.
