Not Scandinavian high tech, but it's cheap and you can build this in a couple of days.</span><o:p></o:p></p><p><span style='font-family:"Liberation Sans",serif'>Because I have no idea of what brick sizes may be available from recycling, I can only present the kiln concept, bearing in mind that it can be round if that better suits the materials obtained. The key to using gas like we intend to use, is that it needs the refractory surfaces to create the radiative heating. </span><o:p></o:p></p><p><span style='font-family:"Liberation Sans",serif'>1. The gas enters the combustion chamber right low to the floor layer of brick, and blasts onto a target brick/s to split the flow around the central core and stack of test tiles. </span><o:p></o:p></p><p><span style='font-family:"Liberation Sans",serif'>2. Bricks standing on end in the combustion chamber have a layer of brick on top, set out to form a grill/grid lattice on which the test tile stack is supported. (we don't know if the base of the tile stack needs a blank flat area).</span><o:p></o:p></p><p><span style='font-family:"Liberation Sans",serif'>3. The gas exits at the top through the centre of a removable cover, the hole can be reduced if necessary by placing a brick over part of the hole.</span><o:p></o:p></p><p><span style='font-family:"Liberation Sans",serif'>4. The lid cover might have to be made from refractory cement, or a metal clamp band be used to hold bricks together. That could end up quite heavy.<br><br>See how that fits in with what you can do without many $$.<br>Doug W.</span><o:p></o:p></p><p style='margin-bottom:12.0pt'><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>On 09/01/17 03:10, Paul Anderson wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal style='margin-bottom:12.0pt'>Rolf, <br><br>Good update.
