Who understands how lampe berger burner stones work or ceramics?

Question:I want to create a stone for a lampe berger type alcohol burner. I know it is made from ceramic (what type etc) and platinum but is it possible to make one at home?

If not where could I buy one that is larger and with more stone then the lampe berger ones. I have a project I am working on but I would like some options.

Thanks for any tips.
