TimberSIL employs sodium silicate, a mixture of sand and soda ash used
since the 1800s in detergents and as an egg preservative. Lumber soaks
in it under pressure, then bakes until an insoluble matrix of amorphous
glass hardens throughout the wood. No amount of rain or wear will
remove it-bugs can look, but they can't touch. $4.50 per 8-foot 2x4

Did they happen to mention how one cuts this "glass filled" lumber and
the nature of the dust?

Best guess without an MSDS - silica dust and wood dust. Long-term exposure
to silica dust = silicosis.
