Albert Barnes Commentary Leviticus 11:35

"And every thing whereupon [any part] of their carcass falleth shall be unclean; whether oven, or range for pots, it shall be broken in pieces: they are unclean, and shall be unclean unto you." — Leviticus 11:35 (ASV)

See Leviticus 2:4. The word rendered “ranges for pots” has been conjectured to mean either an excavated fireplace, fitted to receive a pair of ovens, or a support like a pair of andirons.
