The first commercially available acrylic paint. It was prepared from pigments suspended in a solution of n-butyl methacrylate resin and solvent, developed by Leonard Bocour and Sam Golden in the mid-1940s. Magna could be diluted with turpentine or mineral spirits, had a fast drying time. and could be combined with oil paints. It dried to a hard, matte film. Manufacture of this paint ended in the 1970s.

Organic compound used as a catalyst and as an ingredient in consolidant in stone conservation.

A water-soluble compound created by bubbling carbon dioxide through a suspension of magnesium carbonate in water. In conservation, magnesium bicarbonate solutions are used for deacidifcation of paper.

White crystalline salt that occurs in nature as the mineral magnesite and may be prepared artificially by precipitation. It is used in pigments, inks, glass, ceramic glazes, and dentifrice. Magnesium carbonate has also been used as a sorbent powder for water-free (dry) cleaning of jewelry, doll hair, and other items. Aqueous solutions of magnesium carbonate are used for neutralization and alkalization of paper.

Inert pigment made primarily of the white crystalline salt, magnesium carbonate.

A white salt used medicinally as a laxative and anticonvulsant. In conservation science it is encountered as a salt weathering deposit on stone.

The magnesium salt of magnesium sulfite in sulfurous acid appearing as colorless crystals or white, crystalline powder. It oxidizes to sulfate on exposure to air and loses all its water at 200 degrees fahrenheit. It is used as an adsorbent and absorbent, as an agricultural chemical, in the manufacture of paper pulp, as a wastewater treatment, and etc.
