Etymology
Clinker for the hard mass left after burning comes from the same old word klinker, meaning a hard, fused piece like a small tile; after coal or wood burns, it can leave hard lumps that look like tiny burned bricks. A helpful way to remember is to think of these lumps as 'burned bricks', which is why a clinker is the hard, incombustible mass left after a fire.
