What does asbestos look like?

It can look different depending on the material.

It doesn't look like just one thing. Was manufactured in products like old linoleum, siding, fireplace backs, furnace linings, etc. Anything newer than 1968, probably doesn't have it. If older it could.

Raw asbestos looks like small fibers. It was mixed into compounds to manufacture different products because of it's fireproof properties. It can't be seen in the finished item. There are test kits for testing if something contains asbestos. Anything prior to 1978 claimed to be fireproof or fire resistant more likely has asbestos in it. Hard vinyl tiles, pipe insulation, fake fiber brick siding, etc. Vermiculite insulation from certain quarries had asbestos in it.

Materials containing asbestos were used in commercial buildings, domestic properties and outbuildings. Asbestos containing materials (ACMs) can be found both inside and on the outside of buildings, with some being more easy to identify than others.

It should be pointed out that although asbestos can be presumed from a visual inspection, its presence can only be confirmed by taking a sample and having it analysed in a laboratory

here are pictures you can see the fibers in almost all the products it was put in especially older products that were made with it, with newer products made in later years the asbestos was finer smaller threadlike structures harder to detect by eye. http://www.asbestosnews.com/asbestos/pictures/ some more http://www.merryhillenvirotec.com/what-does-asbestos-look-like/

Thank you all so much for your explanations and for taking the time to answer my question. I appreciate it. I have a friend who's house was built in 1960 and it has a tile floor, wondering if could have asbestos underneath. Thank you again.
