Calcspar is commonly used in the production of cement and glass.
Calcspar is derived from the word 'calc' (from Latin 'calx', meaning lime) and 'spar' (from Old English 'spear', meaning a mineral or crystal). The term refers to a type of mineral that contains calcium carbonate, often found in crystalline form.
Think of 'lime' ('calx') as a key component of calcspar, which is a mineral that contains calcium.
