There is a derelict huge brickworks kiln that looks like this Hoffman kiln in Newtown, Sydney, N.S.W. I saw it 4 months ago when I was down there visiting my daughter. I thought it would be a wonderful place for a potters' community facility. It had a separate building that could be used as a gallery. Imagine if possibly a govt.grant could be used to revive it, if not entirely as a working kiln, but as studio space, etc.

In Britain there are deposits of clay containing a small amount of oil. By use of a series of ovens arranged in a loop similar to the Hoffmann scheme it is possible to fire the bricks using no external fuel with the heat from the adjacent oven bringing each new batch up to the ignition temperature of the oil. This type of brick is called a Fletton or London brick and is still in wide spread production. It is estimated there are five million houses in Britain built of them.

Thank you for this gold-mine of knowledge of brick-production. In Fredrikstad, Norway we are a small group digging out the remains of the last brickwork, planning to use the site for outdoor concerts and plays. During the winter we make fires and serve hot chocolate to strollers. At the moment the homepage is down, but try itlater www.ettertid.no og www.narnte.no

We live a mile from the Richmond Brickworks, on the north San Francisco bay. Pretty spectacular. Excellent article, well written!

If you are in Berlin/Germany you can visit the "Ziegeleimuseum Glindow" (40km drive from Berlin) which has a working Hoffmann kiln. The have walk-throughs and since the kiln is still in use, you can get a nice feeling for the temperature in these places :-)

Can someone explain me the principle of coal firing from kiln top in a Hoffman kiln and the consequent dumper opening and closing orders and timings while the fire is moving inside the kiln loaded with green bricks @ 1.2 meter/hour. Any appropriate books that explains the above phenomenon in step by stem would also be helpful.
