I bought a variety of clay pots--some have black paint on the inside to protect the decorative exterior from minerals and fertilizer from leaching through and, some do not--What is that black material that is painted on the inside of the pot? And can I buy it at Home Depot?

It could be several things from a black asphalt based material to some type of paint. Ask in the paint department for something that will coat and seal a Terra Cotta pot and they can suggest some good options.

Thanks for the question. Please stop in again soon!

I purchased a couple clay pots with the black coating inside of them. Is it safe to grow vegetables in these pots? Thanks for Your time and help.

I think it's some sort of protective coating, and it's meant to prevent the water from leaking and keep the pot in good condition. I'm sure the guys from Home Depot will understand what you are talking about. For example, I got protective floor coating Jacksonville to protect my garage floors from humidity and all the possible damages and somehow I think it's similar to your question. I think that pots that don't have that protective layer on the inside are not meant for gardening or in general for plants because they will fall apart in time.
