Firing pottery is a process that nearly every potter must go through and is often the first step to becoming a professional potter. However, firing pottery at home can be difficult and time-consuming, and without the proper equipment, it can be dangerous. This article will help you get your pottery back from the kiln safely.

Whether making pottery dolls, mugs, plates, or bowls, if you’re planning to churn out pottery on the regular, you will need a kiln. Firing clay in a kiln is also necessary if you plan on selling your art, as firing in a kiln ensures you properly dried your pottery and that your glazes didn’t crack during firing. However, a kiln is an expensive tool often out of most people’s reach. Luckily, you don’t need a kiln to make pottery. You can fire pottery using the microwave and an oven. Just follow these easy steps to fire pottery in a microwave and oven.

Fire Pottery Safely

Fire pottery is arguably the most exciting but also the riskiest form of pottery making. From clay to firing, there’s a lot that can go wrong. So, how can you create beautiful pottery safe to perform?

Here are some tips.

Fire pottery is a fun hobby for people of all ages, but there are a few things to be aware of regarding safety. Using your pottery kiln safely is a must. This quick guide will help with anything you need to know in order to fire your pottery safely.

Primitive kilns

Kilns are ovens that are highly programmable and adjustable. These ovens can be used for a variety of items, including ceramics, pottery, glass, and metal clay. Because of the way kilns work, you can have complete control over the temperature and environment, allowing more flexibility in your creations. In this piece, we will take a look at a few primitive kilns, highlighting their use for ceramics, pottery, and metal clay.

The Outdoor Firing Process

Primary fire

Primary fire is a devastating situation that happens when the fire starts in a basement, attic, or other areas above the main floor of the home. The fire can quickly spread through the upper floor, especially if there are combustible plants, curtains, or furniture, such as mattresses or beds, that are exposed. The most commonly shared story of its kind is the 32-year-old woman who was burned to death after a fire that started in a carport flat above her garage spread to the upper floor of her home.

Kiln Setting

“Kiln settings” is a term used to describe the clay used for pottery, particularly pottery for firing in a kiln. “Kiln” is actually short for “kiln firing,” which is the process used to harden pottery. A potter will use specific types of clay and firing temperatures to create different types of pottery.

Secondary fire

Secondary fire is a fire in clay. It results in a fire that spreads through the surface layers of clay. If the clay is used for building, it can cause destruction of the structure.

Secondary fire from a clay kiln is fairly normal. The secondary fire is the extension of the firing cycle. The kiln needs to be cooled down from the firing before a second firing can occur, so first, a cooling period is incorporated into the firing cycle. The melted glass is heavy and can now fall from the melt pool. The kiln is fed with sand, and because of this, our kiln never goes out of operation. The whole firing cycle takes 8 to 12 hours.

Cool down

“Cool down” is the term used to describe the process of reducing the body temperature, and it’s caused by sweating. Cool down occurs when the body starts losing heat after exercise.

Take an ice-cold shower and cool down. That is unless you are a very serious exerciser, in which case you may have to pace yourself. Another surefire way to cool down is to drink some water. Although consuming large amounts of water can make you feel bloated, drinking water regularly during the day puts you in the habit of taking small sips throughout the day, which can help avoid dehydration.

Firing pottery without a kiln is possible by using materials that fire at high temperatures. However, firing pottery without a kiln is not recommended.
