Glass Fracking...
Glass -
Fracking [
frak-ing ] Noun; Laser educed molecular
hydraulic surface fracturing.
A simplified definition:
Glass is primarily a
collection of silicon molecules. But that is not all. There is also
water molecules trapped between them (among other things). Infra red
laser light passes clean through silicone, but water absorbs the
light. In doing so, the water molecule absorbs the energy from the
laser and expands. When this happens, the surface silicone fractures
giving an etched texture to the surface.
So, why does it only
happen on the surface? Silicone below the surface does not fracture
because it has more silicone molecules surrounding it thereby
strengthening the bond. Strength in numbers prevents the fracture.
Why does the laser light
not also fracture the glass on the exit side? Because it has been
defused (defocused) as it passes through the glass by the silicone
itself and its impurities.
This will not ware
off like printing as it is actually in the glass, not paint on the
surface.
This is my contribution to an auction basket for a school
fundraiser. Ya, a freebee, but for a friend.
I can frack logo's into mixer glasses as shown above for $5
each (glass included) in low quantities. Case quantities can be
negotiated.
The coasters are made of laminated felt. They are
$4 per pack of 9. Again, higher quantities can be negotiated.
