Porous ceramic disc

Hello we\\\'re a company in the Cannabis field and we produce a range of vaporisers here in Shenzhen and China. We currently are working on a disposable product, a coin size ceramic disc made out of porous ceramics. To better understand the material we would have the following questions:
- What kind of porous ceramics can you handle?
- What are the heat properties of each?
- What are the options when it comes to hole sizes and distribution?
- Regarding costs: we have a first drawing that I can send you. I would be interested to know your price point.
Best
Sebastian
