Hi forum member,
Just a little technical info.....
I just wanted to make members aware that Ceramic Fibre Blanket/Boards or CF Blanket/Boards as it can be known are classed as carcinogenic products. We wouldn't advise the use of it in wood oven construction or for use by anyone other than professional installers, based on current knowledge.
There are alternative products to Ceramic Fibre, that work in an extremely similar manner such as LBP HT blanket (which is a bio soluble product) though a little dearer (£10 a roll, more expensive approximately, than CF blanket), though far safer to use and calcium silicate boards as an alternative to CF Boards.
CF products are generally used in the Steel mills and Glass works and are installed by professionals and as such its surprising, with the current information we have on the product it is still available for sale through outlets on eBay.
I do not feel this will continue for much longer though as I believe tougher EU/UK legislation on CF products will come into force shortly, which will require licences possibly to buy/sell these goods, and as such only the large furnace builders may continue to use these products. Who knows?
If anyone wishes to discuss alternatives we would be pleased to assist (info@kilnlinings.co.uk), or you can purchase the more user friendly alternatives 24/7 through our website Kilnlinings.co.uk
All the best
Liam

Many thanks for the update/info.......I didn't know the difference myself, but as I always buy my products from you for my personal enterprise then I know I have always used the correct products for the oven's I have built for family, friends, communities and private customers.

I bought most of my material from kilnlinings - opted for the CF board/blanket as the biosoluble alternative, being bio-soluble meant that it pretty much disintegrated when wet.
My oven is outdoors, and as I'm a (very) slow builder, it took me about a year before I got it suitably protected from moisture.
I did know about the carcinogenic properties, so I bought a set of disposable overalls on eBay (£1), plastic gloves from a petrol station, and a respirator/gas mask (£10 or so for a 3M thing with replaceable canister filters - perfect for when the dog farts). I dampened everything after working with the board, took it off and ditched it before having a nice long shower.
Cutting the board was my biggest concern - I sprayed it a little with water to reduce dust then cut it by pressing a sharp knife downwards (no saws or other things that flake bits).
Is this the right way? No idea... give me another 40 years and I'll let you know if I have lung cancer... but I reckon a single exposure, with the precautions I took, shouldn't be too bad.

Yeah, I also am interested in this.
For the majority of people who build themselves a wfo, they will only come into contact with CF board and CF blanket once in their lives. How hazardous is it to handle and cut these materials in that situation? Providing simple sensible actions are taken, i.e any cutting to be done outdoors, wearing a mask etc.
Also, on my oven, I am at the stage where I have wrapped the dome in CF blanket, but it will be spring before I get it covered with a render. Its an outdoor oven, would I need to cover the CF blanket over with a tarp or is it fine as it is?

Oh yeah, definitely cover it all up Allan, but try to do it in a way to allow free passage of air around it all. Some sort of strung roof, or very well pinned down gazebo.

Yeah it is covered with a well anchored gazebo Danno.
Im not sure if I should be concerned about the fibre blanket being carcinogenic and being exposed?
i.e will any fibres be blown about etc?
I have chicken wired the blanket now, so anything at all would be really limited.

Can't comment on the blanket - but make sure the gazebo is well anchored... My neighbors were not impressed when my gazebo (held down by the 4 strings it came with) decided to change back yards...
