Question
Is it true that a glass table does not need “place-mats” to differentiate between dairy and meat?
Answer
The custom is to be lenient and allow glass (which is not used in the oven or other similar place) to be used for both meat and dairy. One needs to make sure, though, that it is perfectly clean. In fact, many are careful not to use it for both meat and dairy, even when clean.
All the best,
