Leviticus 11:33-35

³³and any earthen vessel, into the midst of which any one of them falleth, all that is in its midst is unclean, and it ye do break.

³⁴'Of all the food which is eaten, that on which cometh such water, is unclean, and all drink which is drunk in any such vessel is unclean;

³⁵and anything on which any of their carcase falleth is unclean (oven or double pots), it is broken down, unclean they are, yea, unclean they are to you.
