Peter Peterson wrote:In one of your posts at Permies you say: “... a round ceramic fibre tube one. The bricks are there only to fix this tube in place.” Can you tell me (us) a little more about this tube? Where to buy it? I am in Germany this days.

Every now and then this video and/or the pictures in it are passing by, leaving me grinning like a Cheshire cat...

This is made from ceramic fibre, the same stuff as superwool. The tube is made using vacuum with an added binder and is used in industrial processes such as steel melting. It is highly heat resistant, insulating and very little mass, ideal for a heat riser. Try googling "ceramic fibre tube", I've heard of one supplier in Belgium but there should be suppliers all over the world.

The ones I had from Belgium are bought from Joris Pouls, who's building his own version of batch boxes nowadays. He's the one who started to use those superwool risers some years ago. See his website.
