9 x 9 VAT asbestos question

What kind of asbestos was used to augment those notorious 9 x 9 vinyl tiles? White (Chrysotile), Brown, or Blue?

Dark vinyl-asbestos tiles used, for example, a mixture of 40 parts asphalt or gilsonite, 60 parts asbestos floats, 30 parts powdered limestone, and pigments (parts by weight). Another typical mixture cited by Rosato contained 70% asbestos fiber.
Originally, asphalt floor tile was produced by mixing heavy asphalt solutions with a high percentage of asbestos fiber, hardening the tile by evaporation of the solvent. This procedure produced very dark floor tiles,. To obtain brown or intermediate colors, Gilsonite was used, dissolved in naphtha.
"Modern" asphalt tile (1950 and later) contained little or no asphalt. Rather than using asphalt or gilsonite binders, this later product used synthetic organic resins and additives or plasticizers based on petroleum
Rosato cites another flooring material from the 1950's called asbetic flooring which was a mixture of ground mother rock and the shortest, otherwise unusable asbestos fibers.

Other sources such as the Rotterdam Convention PIC archive, [citation needed] note that while vinyl-asbestos floor tile ingredient mixes varied by manufacturer, typically vinyl-asbestos floor tiles contained:
  • Asbestos - 5 - 25%
  • Binder - 15 - 20%
  • Limestone - 53 - 73% [note that some products used asbestos powder as filler]
  • Plasticizer - 5%
  • Stabilizer - 1 - 2%
  • Pigment - 0.5 - 5%
Short or vegetable pitches. But asbestos fillers remained the main ingredient in "asphalt" tile. - Rosato.

Wow, that was exhaustive. Thanks.

Any idea of the hazard this stuff poses? Our tile guy scraped up about 20 feet of this stuff in our entry way using heat and a putty knife. The tiles weren't coming up whole (breaking into 5 or 6 pieces), but there wasn't really any dust. No precautions were taken.

Also, can you explain what asbestos being "part of the matrix" actually means?
