The materials you require

The latest talk about the electric kiln, this device’s most widely used variation. Mainly for this, you will need everything for a circuit, the main base and heating element, bolts and nuts to fit it all together, soft fire bricks for insulation, angel iron, ICS controller, hand router, Kaowool, tin snips, and other small to big helping tools.

Understanding the purpose of every material and how you can use them is a lot more important while making these devices than it is following any list step by step. You will find a wide range of different methods by which you can make a pottery kiln across the internet. Make sure to read through them all and do your research before you start the process.

First, start with the structure

The structure of this device mainly refers to the channels and the bricks. These channels are where you will put the heating element for your device. Using a hand router is better than a drill for this step. Two of your bricks will have identical groves, and one will have two horizontal groves.

These groups are essential to fit your heating element, so if your heating element is of a different shape, your groves will follow that.

Adding the heating element

You can use a coiled element to heat your pottery during baking. Remember to secure your heating element properly by drilling two holes in the back of the groves. Properly securing your heating element is important because it will show movement when you run electricity through it.

Use many pins for this step.

Making the frame

Remember, insulation is so important while making a pottery kiln. Making the frame is where the insulation part comes in. For this, you would want to make a frame of metal, preferably steel. The design of the frame can be and should be very simple. You will have to add two more bricks on the top.

Your frame should suit your purpose as to how big your device is supposed to be and how much pottery you hope to insert into it simultaneously. It should also fit well around your heating element. It should be secure and insulated.


Making the door

The kiln’s door is the last step to a secure and safe device. You can use aluminum sheets for this purpose. Your door should at least be one inch thick in the center. Insulation is something that cannot be forgotten yet. Make sure your door fits nicely into the opening at the front of your kiln.

You can attach the door using a simple hinge. You need to cut the Kaowool fiber in a shape that matches the door and wrap it around it. If you are a sucker for details, you cannot afford to forget the handle.

Completing the circuit

Your coiled heating element must be attached to a safe and secure circuit. Make sure to use proper wiring, a working switch, and resistors if required. Use a power cord that serves your needs. Make sure the connection fits securely around your device; you can use a nut and bolt for this.

Now plug the device into the ICS controller and the controller into the socket. You switch on the power input after you are absolutely certain that your circuit is safe and insulated.

At this stage, do not forget to give your pottery kiln some test runs in a controlled atmosphere and make all the necessary changes. It might be that your device needs a different setting than the one you started out with. If your device needs these changes, allow it to cool before you lay your hands on it.

A few things to remember while making your pottery kiln

Some pottery makers use the additional step of baking their pottery once after applying decorations to it. Know your needs before you go on to make a kiln.
