Able to be shaped or formed by pouring liquid metal or other material into a mold.
From Middle English 'casten' (to throw, shape) via Old Norse 'kasta,' combined with the suffix '-able' meaning capable of.
Any material that's 'castable' has a special property: it must flow when hot or liquid but solidify into your desired shape—this is why bronze was so revolutionary for ancient civilizations.
