AIM Kiln 1413
|Host Area||Small Metals|
A kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Kilns have been used for millennia to turn objects made from clay into pottery, tiles and bricks.
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)
There are many different Types of kilns, developed by numerous cultures all over the planet. kilns operated by electricity were developed in the 20th century, primarily for smaller scale use such as in schools, universities, and hobby centers. The atmosphere in most designs of electric kiln is rich in oxygen, as there is no open flame to consume oxygen molecules.
plugging it in Each section of the Aim kiln has its own plug. Each plug pulls 120v on High. In the small metals corner each outlet is its own 220v circuit. Thus, if you plug two sections into the same outlet it will trip the breaker. For proper firing each section in use must lead to its own outlet giving it serous octopus vibes.
Loading For biscuit firing, green were can stack and tough each other but cannot touch the interior walls of the kiln or coils. For a glost(glaze) firing, glazed surfaces will melt and adhere to anything they come in contact with, so, make sure your wares have space between them, a couple millimetres will do. Use kiln furniture, shelves and posts to utilize space effectively. Stack shelves wash side up. note, things can shift slightly in firing.
