Both sprues and vents make up the “sprue system,” which circulates molten material from a pouring cup through a refractory mold and allows air and casting vapors such as steam to be released. In lost-wax casting, “sprue” is the term used for the solid wax rods (rarely reeds or terra-cotta pipes) used to create the channels in the mold. Sprues are also the solid metal that has filled the channels upon cooling, which is generally removed during fettling. ]]></LexicalValue></ScopeNote><NonPreferredTerm dc:identifier="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31485016" xml:lang="en">	<LexicalValue>sprue</LexicalValue>		<dcterms:created></dcterms:created>		<USE>http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31485015</USE></NonPreferredTerm><HasHierRelConcept Role="BT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31323370</HasHierRelConcept><HasRelatedConcept Role="RT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31421286</HasRelatedConcept></ThesaurusConcept></Thesaurus>
