How To Make A Raku Kiln Out Of An Old Electric Kiln

How To Make A Raku Kiln Out Of An Old Electric Kiln

I’m doing a Raku Workshop this coming weekend.  Pretty exciting, as it is the first one I’ve done at my studio.

I’ve had an old kiln that we bought years ago and, in transport, was damaged past repairability – it’s been just sitting around.  So to make sure that everyone gets a lot of firing time in at the workshop, we have converted it into a raku kiln!

Here are some pics of the process:

Here is the old kiln that we used for the conversion to a raku kiln.

The kiln was badly damaged in transport- irrepairable – all the bricks were severely cracked.

The kiln was placed on a wooden base with wheels and a sheet of concrete wall board was placed between the wood and the kiln floor.

The front of the kiln had a hole where the thermacouplar was, perfect place to insert a pyrometer.

A hole was cut through the metal and brick of the kiln wall with a right angle grinder to provide a hole to insert the burner.

A fibre sheet and hog wire were used to construct a lid for the kiln.

High temperature wire and ceramic buttons ( easily made) are used to secure the fibre to the hog wire.

The ceramic buttons are threaded with the high temperature wire.

The button is threaded through the fibre.

Once the button has been pushed through the fibre, pliers are used to twist the wires.

Here she is – firing away!

    Thank you for this post. I have a kiln which I have been saving to do raku in & now I know how. You are a genius

      Great! I forgot to say that we cut an eight inch hole in the middle of the fibre lid to act as a flu. During firing, I cover it half with a piece of fibre. Good luck!

What do you think?
