0.9mm to 1.4mm K-A1 Kiln Furnace Resistance Wire. The wire is sent in one continuous piece, let me know if you need a custom length and I will try my best to accommodate. 

The sample pack includes 0.5m of every diameter of wire if you prefer to test before you buy a longer length. 

Perfect for homemade electric kilns or replacing the element on an existing kiln. It is chunky enough to last a considerable length of time at high temperature without being so thick as to be difficult to work with. The AWG stated are approximate, the mm diameter values are the accurate measurement.
