What if it flakes off? How structurally stable is it? If a wide variety of things start using it, will it increase the risk of silicosis ( http://en.wikipedia.org/wiki/Silicosis ) when using these products?

Concerns of breathing in this silicate have been popping up a lot in this discussion (especially concerns about silicosis). I’d just like to point out that we’re discussing very small quantities; nano-coatings of ~100nm, only 15-30 molecules high as mentioned in the articles. Wikipedia states that the silicate clusters ascribed to silicosis each have a diameter of ~10 microns; each clusters is 100 times larger than t…

They say a coating lasts about a year, which is what is prompting this type of questions. What happens to it after a year? Does it stick to various things that come in contact with the coating? Does it break off and fall to the floor?

Saying the coating lasts a year may imply that within a year the coating sustains enough damage to render it less effective. For instance 99% of the coating may be intact while a small portion has fragmented off due to imperfections in the formation of the initial layer. Additionally many surfaces, especially countertops, are themselves damaged at the micron scale in regular use. If a layer of the initial surface fragments off it will leave an uncoated surface behind.

There additionally may be other mechanisms by which the coating is rendered less effective within a year, but I highly doubt a significant portion of the coating detaches from the surface within a year.

Huh? Asbestos has been known to be harmful for a long time. http://en.wikipedia.org/wiki/Asbestos#History_of_health_conc...

Cigarettes, DDT, Agent Orange, radium, hormone-leaching plastics, certain pharmaceuticals, antibiotic-laced meat. All were known to be harmful and were subject to a cover up to promote consumption. You can debate his example, but his point stands.

I can agree with all of those except 'antibiotic-laced meat'.

And some things, like 'certain pharmaceuticals' (whatever they are) and most certainly DDT still are very useful.

We can trace our bedbug epidemic to the stoppage of DDT. Nothing else is as effective.

This seems like the kind of report they'd show as a flashback in a post-apocalyptic film :)

In my mind, especially because of this:

>[Neil McClelland] said soon almost every product you purchase will be coated with liquid glass.

Because such things are probably good for you, right?

I wonder if using the word "glass" is a good idea. I could see some public outcry when people hear that their hamburger and catheter has a "thin glass coating". Perhaps it will have a brand name later ...

The nonstick coating wore off your pan? Nonstick coat your food!
