This lathe produces precise geometric patterns and creates incisions to the surface at an even depth, which maximises light refraction. Guilloché engraving is often enhanced with a thin layer of translucent enamels, which increases the luminous quality of the engraved patterns. This combination is referred to as guilloché enamelling, and became a common decorative feature of Fabergé’s output. ]]></termNote><termCreatedDate>2026-03-30 20:25:41</termCreatedDate><relation><relationType>UF</relationType><termId>31318109</termId><termName>guilloche engraving</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31304960</termId><termName>engraving</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31311415</termId><termName>guilloche</termName><termType>PT</termType></relation></term>  </Zthes>
