Clays are composed of hydrated aluminum silicates, such as Kaolinite, Illite, Palygorskite, Attapulgite, Bentonite, and Montmorillonite. Small amounts of other minerals can change the color (white, yellow, brown or red) and texture of the clays. Clays may include all earths that form a paste with water and harden when heated. ]]></LexicalValue></ScopeNote><NonPreferredTerm dc:identifier="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31320464" xml:lang="en">	<LexicalValue>clays</LexicalValue>		<dcterms:created></dcterms:created>		<USE>http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31320463</USE></NonPreferredTerm><HasHierRelConcept Role="BT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31306143</HasHierRelConcept><HasHierRelConcept Role="NT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31344436</HasHierRelConcept><HasHierRelConcept Role="NT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31344437</HasHierRelConcept><HasHierRelConcept Role="NT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31344438</HasHierRelConcept><HasRelatedConcept Role="RT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31319854</HasRelatedConcept><HasRelatedConcept Role="RT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31320230</HasRelatedConcept></ThesaurusConcept></Thesaurus>
