Beautiful sepia gradation images were created by using albumen and silver chloride. Albumin is pronounced ; formed from Latin&colon; "albumen" "(egg) white; dried egg white". Common processes involved chemicals such as glycerin, magnesium nitrate, tannic acid and albumen. Ovotransferrin (conalbumin) is a glycoprotein of egg white albumen. The endosperm is also called the albumen of the seed. The product is dried and mixed with egg albumen, which acts as a binder. In a commercialized setting, dried albumen is used as opposed to fresh egg whites. Seeds are solitary with no albumen around the embryo. Egg albumen is expensive and only used for the lightest shades. Ovomucin is a glycoprotein which may contribute to the gel-like structure of thick albumen. The albumen print process first used more than years ago, produces brownish tones. Ovalbumin is the most abundant protein in albumen. Collodion printing was typically done on albumen paper. The white contains exterior albumen which sets at the highest temperature. Strands of albumen would often be fully ingested in as little as twenty minutes.
