Billy starts of with configuring the computer
interface.

You can see the flask gets its special coating
which is ground glass mixed with other materials that will be lasered into
the flask

The laser is set for the correct height. On
the right is a flask that Billy took a grinder to to see how easy it would
be to remove the engraving and as you can see it really was impossible to
remove it with anything like normal use. Even the grinder has problem
trying to remove this one

And that's the laser engraving done and then
when washed and polished the final product is ready |
