How can you vitrify your clay creations if you do not haveA couple of inventors have sucessfully used a. A Rocket Oven uses little fuel yet is capable of maintaining temperatures up to 1200F (and greater) degrees.There is little smoke and your clay creations will become durable. (You could probably make this by lining clay in a bbq that has a hole in the bottom).Watch below for how you can make a. (Notice that the inventors placed a deflector plate between the flame from the rocket stove below inside the cooking chamber to prevent scorching food).A New Zealand Potter (named Peter) built seven different wood-fired kilns before finding success with design number seven. The first reached over 1000 degrees celsius within two hours, exploding all his pyrometric cones with the rapid firing.Another option if clay which some might like to try is the Rocket Barrel Bread Oven which can easily be used instead as a kiln. The materials include a metal rocket stove below a metal barrel and a chimmeny. It combines the Institutional Rocket Stove chamber which uses very little wood to reach 1100 degrees celsius - hot enough for a glaze and bisque fire.
