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. ]]></LexicalValue></ScopeNote><NonPreferredTerm dc:identifier="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31318109" xml:lang="en">	<LexicalValue>guilloche engraving</LexicalValue>		<dcterms:created></dcterms:created>		<USE>http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31318108</USE></NonPreferredTerm><HasHierRelConcept Role="BT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31304960</HasHierRelConcept><HasRelatedConcept Role="RT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31311415</HasRelatedConcept></ThesaurusConcept></Thesaurus>
