If a boiling hot but clean fleishig pot lid was placed on a clean milchig place mat by mistake does the lid and/or the place mat become treif?
Answer:
No, if the lid was clean, then the fact that it was placed while hot on a dairy surface does not affect either the lid or the surface - the place mat.
This is because one utensil does not absorb from another, even when hot.
This should not be done, however, if the lid is wet (with a parev liquid; this will get into the issue of nat bar nat) - though the lid and place mat will nonetheless not change their status.
Best wishes.
