High temperature ceramic electric kiln

Types of High Temperature Ceramic Electric Kilns

A high temperature ceramic electric kiln is a type of electric kiln that reaches very high temperatures. High-temperature kilns are used for ceramics that require more robust firing processes, such as stoneware pottery and porcelains. High-fire ceramics can withstand harsher environments, making them ideal for kitchenware and other items that need to stand the test of time. Besides, the clay bodies used for high-fire ceramics are often denser and less porous, and they are also typically balanced with low-expansion glass, making them more durable, making them suitable for such products.

High-temperature electric kilns can be classified into the following types based on features and designs:

• Top-Loading High-Temperature Ceramic Electric Kilns

  Top-loading kilns are often donut-shaped and have a dual wall of insulating material. The kiln's lid is the only entry point. To load the kiln, the potter removes the lid, which is hinged or detached, and places the item inside. These kilns require more strenuous firing because they perform so well when fired vertically. The heat rises and surrounds the item from above.

• Front-Loading High-Temperature Ceramic Electric Kilns

  Front-loading kilns have doors that open like an oven to place products inside. A front-loading electric kiln is similar to a large oven except that it fires items at extremely high temperatures to harden and dry them. The ceramic electric kiln can be square or rectangular, and some may even have two levels. A metal door protects the kiln.

• Walking Stick High-Temperature Ceramic Electric Kilns

  The pottery sticks, also known as dowels or props, are placed perpendicular to the floor of the kiln in rows, and the pottery is placed on top of them. This arrangement creates a grid-like pattern in which the supporting sticks act to stabilize and hold up the pottery during firing. The configuration of the supporting sticks is similar to that used for loading lumber in a sawmill. Loading pottery into a “walking stick kiln” requires some skill and involves a “poke and hope” approach, as there may not be much room for error.

• Glass Fusing High-Temperature Ceramic Electric Kilnss

  Glass fusing is the process of heating glass to a temperature at which it will soften and fuse together to form new shapes and permanent combinations. A high-temperature glass-fusing electric kiln can melt or fuse metals, including gold, copper, silver, and bronze, to make jewelry. These kilns usually have a digital controller for scheduling firing and cooling cycles. The instrument can also be used to program the kiln to hold at various temperatures for extended periods; thus, making it ideal for glass artists and jewelers.
