I bought this shelf for my Prometheus 7 kiln that I bought from Metal Clay (an excellent kiln by the way I haven't had a duff firing yet!) and have since bought another as I like to have a back up (my mother calls me Mrs Two Buy!), I think these kiln shelfs are well made they do the job required of them and are a very good price and as ever swiftly delivered by Metal Clay!
Ceramic fibre shelf perfectly sized for our larger PRO7 sized kilns.
Place your pieces to be fired on this to protect the floor of the kiln and to help you remove the fired pieces after firing. You can place the shelf directly onto the base of the kiln floor, but using kiln posts is a good idea to allow for air circulation. We recommend you use three posts (rather than four) to ensure the shelf is stable. Place on at the back centre of the shelf, and two at the front, one per corner.
The shelf will go brown on the first firing, this is normal and is the binder burning off - it will go back to an off-white colour once it has been fired at about 600-800C for a little while.
The shelf measures 205mm x 155mm x 10mm.
The shelf will have uneven, slightly rough, edges due to how it is made and compressed during its manufacture. Some may also have slight discolouration or marks due to the manufacturing process, but it will not affect its performance.
Choose to add a set of 3 kiln posts, small or large, and get a nearly £2 savings compared to buying the shelf and the posts individually.
Small kiln posts are: Approx. 20mm Diameter x 14.5mm H
Large kiln posts are: Approx. 17mm Diameter x 22mm H
