How does a Feller Kiln work?
Feller kiln: brought contemporary design to wood firing by re-using unburnt gas from the chimney to heat intake air before it enters the firebox. This leads to an even shorter firing cycle and less wood consumption. This design requires external ventilation to prevent the in-chimney radiator from melting, being typically in metal. The result is a very efficient wood kiln firing one cubic metre of ceramics with one cubic meter of wood.
How is humidity removed from a kiln?
Humidity is removed by a system of vents, the specific layout of which are usually particular to a given manufacturer. In general, cool dry air is introduced at one end of the kiln while warm moist air is expelled at the other.
Did you know?
The word kiln was kindled in Old English as a bundle of c-y-l-n. Unlike many words that descend from Old English, however, kiln is not ultimately Germanic in origin but was borrowed from Latin culina, meaning "kitchen," an ancestor of the English word culinary, which has been a menu option in English since the 17th century. An ingredient in culina is coquere, meaning "to cook" in Latin.

What is hardware in a kiln?
Hardware is everything attached to the bands of your kiln except the controller. This includes the hinge, lid brace, handles, latches, and lid lifters. Most of these components are made of corrosion resistant metal or ceramic. It is extremely important to make sure these items are tightened occasionally. The lid brace is especially important on larger kilns because it supports the lid above your head while loading the kiln.
What is a peep plug?
Peep plugs were originally developed to plug the holes in the kiln that were used to “peep” into the kiln. A pyrometric cone was placed on one or more shelves in the kiln while it was firing. The kiln owner would pull the plug out when they thought the kiln was nearing the end of the firing and look to see if the cone had bent. When the cone bent to the right position, it signaled that the ware had received the proper amount of heatwork and the operator would manually shut down the kiln.
What is a kiln brick?
Kiln brick is made of refractory (high temperature) ceramic material that is designed to withstand temperatures up to 2350 F. It is formed by mixing the crushed material with wood pulp and then firing it to burn out the pulp, leaving tiny pockets of air. This makes the brick very light and, because air is the best insulator, able to contain the heat in the kiln. It is then precisely machined for the various shapes needed.
Why are brick bands important?
The bands that hold the brick together are generally made of stainless steel so they will resist corrosion. They are attached around the brick with worm screws so they can be tightened periodically to keep the brick from getting loose and shifting. It is important to keep the bands clean and dry. Even though they are made of stainless steel they will corrode if exposed to moisture and corrosive materials like salt and sulfur.

Why are car kilns called car kilns?
An alternative design is that the chamber of the kiln is static, and the base of the kiln moves. These kilns are called car kilns because the base of the kiln moves. And the ware travels through the kiln on a car.
What is a gas kiln?
Gas kilns use either natural gas or propane. The kiln consists of a chamber that is insulated with fire bricks. Heat is introduced to the chamber by burner ports at the base of the kiln. Burner ports are basically opening through which lit gas passes. Gas kilns are either have an updraft or a downdraft design.
Why is a downdraft kiln more efficient than an updraft kiln?
Because the heat has no way to escape out of the top, it is forced to circulate downwards again. The hot draft travels down into the kiln chamber and is effectively used to heat the ware twice. For this reason, downdraft kilns are considered to be more efficient than updraft kilns.
How is a kiln heated?
The first one is the way that the kiln is heated. Some kilns are heated by electricity . Other kilns are heated by burning fuel. These are known as fuel-burning kilns. The fuel used can range from natural gas, propane, wood, and sawdust. These are a few of the combustible materials used to heat a fuel-burning kiln.
How were climbing kilns built?

How to melt wax out of mold?
The easiest way to melt wax out of a small mold is in a microwave. Remove any metal clamps you might have added to your mold, then prop it up on clay supports over a small container underneath to collect the wax. Heat in short bursts in the microwave until all of the wax has dripped into the small container.
What is open face molding?
Open-faced molding. Open-faced molding is used when casting pieces where one side is flat, like when making a glass tile or a coaster. To make the mold, pour plaster around a clay pattern and let it set. Once the plaster has solidified, remove the clay and finish drying the plaster mold in the oven.

Pronunciation and etymology
According to the Oxford English Dictionary, kiln was derived from the words cyline, cylene, cyln(e) in Old English, in turn derived from Latin culina ("kitchen"). In Middle English the word is attested as kulne, kyllne, kilne, kiln, kylle, kyll, kil, kill, keele, kiele. For over 600 years, the final "n" in kiln was silent.
It wasn't until the late 20th century where the "n" began to be pronounced. This is due to a pheno…
Uses of kilns
Pit fired pottery was produced for thousands of years before the earliest known kiln, which dates to around 6000 BC, and was found at the Yarim Tepe site in modern Iraq. Neolithic kilns were able to produce temperatures greater than 900 °C (1652 °F). Uses include:
• Annealing, fusing and deforming glass, or fusing metallic oxide paints to the surface of glass
• Heat treatment for metallic workpieces
Ceramic kilns
Kilns are an essential part of the manufacture of all ceramics. Ceramics require high temperatures so chemical and physical reactions will occur to permanently alter the unfired body. In the case of pottery, clay materials are shaped, dried and then fired in a kiln. The final characteristics are determined by the composition and preparation of the clay body and the temperature at which it i…
Wood-drying kiln
Green wood coming straight from the felled tree has far too high a moisture content to be commercially useful and will rot, warp and split. Both hardwoods and softwood must be left to dry out until the moisture content is between 18% and 8%. This can be a long process unless accelerated by use of a kiln. A variety of kiln technologies exist today: conventional, dehumidification, solar, vacuum and radio frequency.
