Calcium is a silvery white metal which is obtained by the electrolysis of molten calcium chloride. It is one of the most abundant metal elements on Earth (41000 ppm), but it never occurs as the pure element, the main deposits being limestone (CaCO 3 ), Dolomite (CaCO 3 .MgCO 3 ) and Gypsum (CaSO 4 .2H 2 O).

Pointing - Farrow & Ball

A warm and delie white. This fresh and uncomplied white is named after the colour of lime pointing used in traditional brickwork. One of our Red Based Neutrals, Pointing has a warm undertone to it which creates the prettiest of spaces when used on walls and always softens the feel of a room alongside strong, traditional colours.

Calcium Metal - an overview | ScienceDirect Topics

Smelting to give the metals involves metallothermic reduction of fluorides or oxides, or electrochemical methods. Metal oxides are converted to fluorides by HF/Ar and purified by melting in an HF/Ar atmosphere. The fluorides are then reduced by the more electropositive calcium metal. …
