[Stoves] Chart of breathable particles

[Kobus]

Fascinating topic.  I remember Tom Reed mentioning a few years back how 
he still has a bit of a cough having worked with fibrous materials on a 
project (in the 70's?).  It made me re-think using riser tubes / vacuum 
formed ceramic fibre and I've gone away from it now (indoor use), having 
developed low density insulated fire bricks with the help of our local 
university.  Don't play with peoples lives, especially when arriving at 
the conclusion that no one really knows what the real dangers are.  The 
less dense the ceramic in question - the more prone it is to wearing out 
- and the eroded material must have gone somewhere??  The higher the 
density of the ceramic the more durable it is, but flame quality 
suffers.  The trick is to find a mid-point and replicate it exactly 
every time.
