Really being a beginner should not deter you from trying different surfaces on pot calls. You will have to learn anyone you choose, even though some are easier to master, slate is a good choice, because of its ability to create friction very quickly, and glass is good if it is conditioned right. Ceramic would be a great choice if you are looking for a less maintenance pot, all you need there is a good striker and some alcohol wipes. But with any pot, it takes practice, watch a lot of internet guru's run theirs or if you are close to someone who has some watch them.
