A silvery-white metal with the chemical symbol Sn. Tin also refers to various metal containers used for food storage or preparation: lidded airtight storage containers made of tinplate or aluminium, open-topped metal containers used for baking (for example, cake tins), and sealed containers made from tinplate or aluminium used for preserving foods — in the UK, ‘tin‘ is often synonymous with cans. Tin‘s corrosion resistance and solderability made it the classic can coating, though acidic foods can dissolve tin, causing metallic off-flavours and elevated dietary intake; modern lacquers and limits on tin migration manage this.
