I have made some corrections to the page in terms of common errors and misconceptions that were listed in the previous version. For those who are interested, I refer you to my article on the topic, which was previously published in the Construction Specifier, a trade magazine published by Construction Specifications Canada : http://www.geocities.com/astximw/mmmf.html --Achim 04:35, 25 April 2006 (UTC)
Mineral wool -> Stone wool?
The term Stone wool is re-directed to this article which is about the production of stone wool. To the best of my knowledge, mineral wool is the super-type of stone wool and glass wool. I think that this article should be renamed to Stone wool and then a new page Mineral wool should be created to point at the two sub-types stone and glass wool. - VicVal 18:06, 7 August 2006 (UTC)
That would be splitting hairs. Stone is made of minerals, which is metal oxides. All mineral wool is made of that, regardless which of the three types you look at. The main constituents in these wools, you will all find in abundance in our lithosphere. I know, as My dad sold it starting in the sixties and I have lived near the stuff for decades, in one form or another. If you do some digging on the net, you will come to the same conclusion. Each of the three types are made of metal oxides (just in different combinations and hence the different melting points and cost variation), which is the same as stone. So there is no point splitting hairs about it. If it walks like a duck and it quacks like a duck...its probably a duck.--Achim 02:27, 15 August 2006 (UTC)
- I agree with the original poster. The article does not explain what rockwool or stonewool is, but talks about it as if it were defined in another article. More explanation needs to be added (rather than expecting to reader to google elsewhere). —Pengo talk · contribs 02:04, 16 September 2006 (UTC)
Sometimes it is asbestos wool, who knows what is in that rock, mineral or ceramic wool. PrinssiFO 22:58, 29 September 2007 (UTC)
So, what is it?
The article says: “Stone wool is a furnace product of molten stone”. That strikes me as bloody imprecise for an encyclopedia article. There are thousands of substances that “stone” can refer to; most of them can be melted. Freederick 01:44, 5 August 2007 (UTC)
It is made from stone, and very usable for insulation. A lot of stone types are available. What type of stone isn't very important when it is stone wool. I bet they don't use gemstones. PrinssiFO 23:09, 29 September 2007 (UTC)
The rockwool factory Pencoed wales told me (2012) that they used basalt from Ireland but different rocks and blends were used for different products. They aslo said it was first noticed in Hawaii where lava was blown by the wind into fibres. I do know they add an 'oil' to make the fibres more waterproof in the final product.Offbeam (talk) 22:23, 15 March 2012 (UTC)
I found an article about "synthetic mineral fibre", and I found it jenerally inferior to this article, so I sujested a merger. Considering it for a minute, I think I'll just boldly insert the redirection. I don't think many people care for safety assessments in the passive voice, which seems to be what "smf" is all about.

Ceramic versus Stone
Isn't ceramic basically igneous and typically porous stone? So, how do you compare them, as in rating ceramic above stone? BrewJay 08:02, 24 October 2007 (UTC)
