☕ - The hot beverage that powers the world!
Coffee gadgets - It's always great to learn about new gadgets. Please share your favorite hardware or full setups. It might inspire newcomers to experiment!
Local businesses - Please promote your local businesses. If you are not the owner of the business you are promoting, kindly ask the owner if it's okay. It would be great if the business has a physical store to include an exterior or interior shot.

One of the advantages of plastic is it's really low thermal conductivity compared to even glass. You're right about glass vs ceramic. Ceramic is about 100x more thermally conductive than glass. Ranked by least thermally conductive to most it's plastic, glass, stainless steel, and ceramic. Each is roughly an order of magnitude greater than the previous.
Of course you can overcome this with anything by warming it before use.
