The whole egg, yolk, or white may be used sometimes mixed with oil and/or resin. Egg white, or glair, has been used as a medium for illuminated manuscripts. It is also used as a size for attaching gold leaf. For the egg white protein that is used in the food industry and in photographic emulsions, use "albumen (egg white protein)." ]]></termNote><termCreatedDate>2026-03-30 20:26:25</termCreatedDate><relation><relationType>UF</relationType><termId>31320603</termId><termName>white, egg</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31306175</termId><termName>egg components as materials</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31340187</termId><termName>albumen</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31374324</termId><termName>glair</termName><termType>PT</termType></relation></term>  </Zthes>
