Barium Carbonate is also known as witherite and used in applications such as bricks, ceramics, glazes, cement, the chemical industry and as a flux. The formula is BaC0₃ and other names include carbonic acid, barium salt and barium monocarbonate. It is manufactured from barite (barium sulfate) and is a white powder that comes in several variations of grain sizes.

Strontium Carbonate is a safe, white powder not to be reacted with acids except under proper supervision. It is a flux and is not very soluble in water. The ceramic industry uses it in making glazes. Many magnet manufacturers use strontium as a major key ingredient. Steel producers are a user industry too. Strontium carbonate is a weak base and is reacted with many acids to produce unique products. The most fascinating application is strontium salts used to create a bright red color in fireworks and flares.

Wollastonite is a calcium inosilicate mineral (CaSiO₃) with a theoretical makeup of approximately 48% calcium oxide and 52% silicon dioxide. Wollastonite is usually white in color. It may contain small amounts of iron, magnesium, and manganese which can give it a gray, red, or brown tint. Wollastonite is an industrially important mineral. It is well known for its good fluorescence. It also has low moisture and absorption properties.
