A thought that crossed my mind. After looking up what was used in Rayburn cookers and all I can find is a reference to a letter that asbestos was never used for loose fill.
Was rockwool around?
Was fibreglass around?

Confusing isn't it - asbestos insulation is produced from mineral found in rock - so I guess that this would class as rock mineral.
I was assured that asbestos had never been used for loose fill by the Rayburn people - back then Rayburn was still the company, not just an Aga brand name.
AFAIK they used rockwool style stuff - when I rebuilt my old Rayburn in the late 70s I managed to get some Rocksil.

Don't know when Rayburns were first built, but I presume rock fibre insulation is an old product.
Aha -
So logically rock mineral fibre can have been used as insulation since the first Rayburn was built.
Now off to do some real work :-)

Caustic soda?

It's on again, I'm sorry I haven't a clue started the latest series today. An earlier series is on Channel 7 -whatever that is.
Why is it £80 to watch free to view?
Vermiculite - how many times must I tell you :-).
Vermiculite ?
How do you spell that?
Seems like rockwool and fibreglass have been around a long time.
Rayburn (aga-rayburn) state that they have only ever used rockwool and fibreglass. I asked them about a 1960s rayburn Nr1.

Which, the hydrated phlogopite or the hydrated biotite one?
isn't that phlogophite?
I think that the real question here is whether the Makita hair-splitting tool is better than the PPPro one (with 3 year guarantee) or the Ferm equivalent.
Corded or battery.
Of course, eye protection and a mask shoudl always be worn...
