One who takes out wood [is liable if he takes out] enough to cook an easily cooked egg; condiments, enough to season an easily seasoned egg; and they may be combined with one another. Nutshells, pomegranate shells, woad, or madder, enough to dye the smallest cloth in a headdress. Urine, niter, soap, saltwort, or eshlag, enough to launder with them the smallest cloth in a headdress. R’ Yehudah says: Enough to pass over a stain.
