Vermiculite cancerous????

Over here the fishing tackle shops use it to keep ragworm and lugworm
(Sea fishing bait) fresh.

I was wrong. Its asbestos that some vermiculite has in it. Vermiculite is not banned here in the US. But then we're pretty slow about banning toxic substances here. We usually wait till a few thousand have died firts.lol

There was one mine that had asbestos in the same vein as the vermiculite, but they closed that mine and it has not been a problem since, but it got so well-known in the gardening industry that it became almost an irrefutable truth that vermiculite is cancerous. You can buy it in large quantities at ulead.com

Kinda like asbestos, it does have useful applications but you should consider wearing a mask when handling the raw material... just in case.

Vermiculite is not going to harm you with or without a mask,as long as you add water to it before you mix with it. Just wear a mask either way !

Basically vermiculite has been mined before accidentally with a seams asbestos so therefore any vermiculite could potentially contain traces of asbestos fibre.

Although not all vermiculite contains asbestos, some products were made with vermiculite that contained asbestos until the early 1990s. Vermiculite mines throughout the world are now regularly tested for it and are supposed to sell products that contain no asbestos. The former vermiculite mine in Libby, Montana, did have tremolite asbestos as well at winchite and richterite (both fibrous amphiboles) â?? in fact, it was formed underground through essentially the same geologic processes as the contaminants. A vermiculite mine in Virginia has also been found to be contaminated by asbestos.[3]

Pure vermiculite does not contain asbestos and is non-toxic, but it can become contaminated over long periods if there is a presence of a secondary mineral called diopside. After millions of years of weatherization, the biotite turns into vermiculite and the diopside turns into asbestos.
