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
