English: The verse could be read as sanctifying anything that touches the altar, even something unfit for it. Chazal limit this: as an offering must be fit, so the object sanctified by the altar must be fit for it.
On the daf / in context: See the cited source for the full section.
Derash on the verse.
The altar sanctifies an item that is fit for the altar, not every object indiscriminately placed upon it.
