Lanthanum :: Lanthanum (n.) A rare element of the group of the earth metals, allied to aluminium. It occurs in certain rare minerals, as cerite, gadolinite, orthite, etc., and was so named from the difficulty of separating it from cerium, didymium, and other rare elements with which it is usually associated.

Clay :: Clay (n.) A soft earth, which is plastic, or may be molded with the hands, consisting of hydrous silicate of aluminium. It is the result of the wearing down and decomposition, in part, of rocks containing aluminous minerals, as granite. Lime, magnesia, oxide of iron, and other ingredients, are often present as impurities..

Roscoelite :: Roscoelite (n.) A green micaceous mineral occurring in minute scales. It is essentially a silicate of aluminia and potash containing vanadium.

Sodium :: Sodium (n.) A common metallic element of the alkali group, in nature always occuring combined, as in common salt, in albite, etc. It is isolated as a soft, waxy, white, unstable metal, so readily oxidized that it combines violently with water, and to be preserved must be kept under petroleum or some similar liquid. Sodium is used combined in many salts, in the free state as a reducer, and as a means of obtaining other metals (as magnesium and aluminium) is an important commercial product. Symbol

Lazuli :: Lazuli (n.) A mineral of a fine azure-blue color, usually in small rounded masses. It is essentially a silicate of alumina, lime, and soda, with some sodium sulphide, is often marked by yellow spots or veins of sulphide of iron, and is much valued for ornamental work. Called also lapis lazuli, and Armenian stone..

Glucinum :: Glucinum (n.) A rare metallic element, of a silver white color, and low specific gravity (2.1), resembling magnesium. It never occurs naturally in the free state, but is always combined, usually with silica or alumina, or both; as in the minerals phenacite, chrysoberyl, beryl or emerald, euclase, and danalite. It was named from its oxide glucina, which was known long before the element was isolated. Symbol Gl. Atomic weight 9.1. Called also beryllium..
