Warm Glass AES Fibre Paper, 6mm

Fibre Paper is great for lining the base of your kiln. This versatile product is also ideal for lining box castings and for bas relief designs known as kilncarving. It can be used a number of times if it is left in the kiln.

Fibre Paper is excellent for kilncarving, simply cut the fibre using a craft knife and place between the glass and the shelf to add texture to your glass designs. See the Kilncarving Tipsheet for more information. We do not recommend firing the fibre above 804C (for kilncarving) unless you are planning to do some coldworking.

This 6mm thickness is extremely versatile, as well as kilncarving you can also use it to form low profile dams when making pieces using frit or when used with fibre hardener you can create rigid moulds that can withstand more than one firing.

Warm Glass AES fibre paper is a safe alternative to Ceramic Fibre. Our AES range is made from Alkaline-earth Silicate Wool (AES) which does not contain harmful Refractory Ceramic Fibre (which we have never sold). AES is bio-soluble and does not accumulate in the lungs, but it can be an irritant and we recommend wearing gloves and an FFP3 mask when handling, especially after firing.


This is an excellent alternative to ceramic fibre but it will not withstand the higher temperatures required for processes such as pot melts.

Please note: This fibre does not give as smooth a finish as Thinfire Paper. Opal glasses tend to stick to fibre papers more than clear and transparent coloured glasses, for this reason we do not recommend fibre paper is used as a shelf separator unless it is used in combination with another separator such as Thinfire Paper.

Customer Questions
Can fibre paper be used in more than 1 firing?

This fibre paper is designed for one time use, but you may get two firings in some applications at lower firings. This is because our fibre paper does not contain harmful ceramic fibre. For more than one firing, try SilkeMat Fibre Blanket which we also stock.
