Hi friendly pottery community! I am in the process of building a raku kiln from an oil drum, and I have been scouring various sources online and in books to try and answer some questions but have had no luck! I thought it might be easier to just ask. 1. What kind of burner should I buy? The raku burner kits from pottery suppliers seem prohibitively expensive, and I wondered if they are putting a big mark up on something which could be bought cheaper from a builders merchant or similar. However, as I am new to this and don't really know much about burners, I don't want to cut costs and get the wrong thing. I gather from my various sources that the best fuel to go for is propane. 2. Fire bricks - what do I need to go for? I think I need to get some to build up a 'combustion zone' at the bottom of the drum, which a kiln shelf will sit on top of, and the burner will be aimed between them to build up heat. The options I see on the supplier I am currently browsing (Vitcas) are refractory and insulation. Are these the equivalent of hard and soft, as I have seen them referenced elsewhere? And how many should i need? It is a 55 gallon oil drum. 3. Am I right in thinking that the hole for the burner to enter the drum should be approx 2 x the size of the burner, and that the vent at the top of the drum should be double the size of the burner hole? 4. Should I get fire bricks for the oil drum to sit on? Or will it be ok just on concrete floor? I expect I'll have more questions as I progress with the build, but thats it for now! Antonia
From the album: kilnsThis is my expanded kiln shed holding all 7 of my kilns and a soldier mixer on wheels. 3 various sized electric including the huge oval in the center, plus 4 various sized raku kilns that I use for obvara, saggar including soluble salts, raku and foil saggar. The pulley kiln is open with the chamber raised. This shed will provide shelter for firing in the winter as well as compliance with open burning during forest fire season. Very much relieved to have this .
