Terumos 10:3

If a person takes warm chullin bread from the oven and places it over the mouth of a barrel of terumah wine, Rabbi Meir prohibits the bread to non-kohanim and Rabbi Yehudah permits it. Rabbi Yosi allows it with wheat bread but not with barley bread because barley is especially absorbent.

Terumos 10:4

If a person heated an oven seasoned with cumin of terumah, bread that is baked in it is permitted to non-kohanim because it only absorbs the aroma of the cumin, not the taste.
