Green Sand: An Introduction to Its Use in Foundries

Green sand is a compound mixture used for casting of metals in foundry applications as a mould. It is 'green' not by colour, but takes the moniker due to the fact that it is not 'set' when the metal is poured into it, rather it is still in the 'green' or uncured state. The name derives from green wood, that is, wood still containing ...

What is Sand - Overview and Geology - Sandatlas

Sand is composed of sand grains which range in size from 1/16 to 2 mm (62.5.2000 micrometers). Sand grains are either mineral particles, rock fragments or biogenic in origin. Finer granular material than sand is referred to as silt. Coarser material is gravel. Majority of sand is dominantly composed of silicate minerals or silicate rock fragments.
