Does one need tevilas keilim on a glass table? And are there any sources for such a din?
Answer:
A table does not require tevilas keilim, because it is not a utensil used for eating on, but rather for putting plates on. Even if one occassionally eats directly from the table, there is no obligation of tevillah, because this is not the general purpose.
As a technical detail, it would probably also be hard to immerse the table in the mikvah, but as noted, there is no obligation at all to do so.
Best wishes.
