AL'U-DEL, n. [a and lutum, without lute. Lunier.]

In chimistry, aludels are earthern pots without bottoms, that they may be exactly fitted into each other, and used in sublimations. At the bottom of the furnace is a pot containing the matter to be sublimed, and at the top a head to receive the volatile matter. – Quincy. Encyc.
