Help Identify Insulation

[John Doem]

Hello,

Recently started doing some renovations in the bathroom of our home, and came across this insulation in the walls. House was built in the 1920's, 1923 I believe. It looks like cotton, I looked at it under 20x maginification and it looks fibrous, almost hairlike. Seems to have been blown in as it comes away loose. Could this pose any asbestos threat? From the look, it seems like mineral wool, but I want to be sure.

Thanks.

Looks like Rock Wool

Thanks for the correction. I knew that. Fat fingers.

No problem Michael, just don't want to confuse the recipient, if you know what I mean.

Who is he? What kind of data collection does he have? Is it accessible by the general public (meaning me)?

Kenton...try: www.inspect-ny.com . That's where the photo in post #2 came from and is Daniel's site. You'll recognize it when you see it.
