pannikin

A durable cup or other vessel used for drinking made of metal and coated in enamel.

1852, Ellen Clacy (diarist), cited in Susan Lawrence, "Households on Australian goldfields" in Penelope M. Allison (ed.), The Archaeology of Household Activities, London: Routledge, 1999, ‘a block of wood forms a table, and this is the only furniture; many dispense with that. The bedding, which is laid on the ground, serves to sit upon. Tin plates and pannikins… compose the tea service.’

Scarcely had we got things fixed and supper under weigh, when a yell from Boteler, 'He's going to spout!' caused us to drop teapot and pannikin, and tumble out of the tent in half no time.

The contents of such a vessel.

“[…] Put the billy on the fire, Jimmy, and we’ll drink him a good voyage in half a pannikin of tea before we turn in.”
