Dupont Glass?

Do any of you know the significance of this Dupont Glass?

Looks rather insignificant to me.

I have a McDonald's glass, it's old school. Smaller than that.

Those numbers look random to me.. unless they are Barometric pressure (Hg) readings?

The man that owned the glass had a thirty year career in offshore oil exploration. I'm curious if the glass has something to do with oil exploration.

Nascar related? They were a huge sponsor years ago.

What is so special about this glass?

Is it bulletproof?
Shatterproof?
Clear crystal?
Exotic material?
Super lightweight?

What?

When you mentioned offshore oil exploration something clicked. Now I have no experience in this area whatsoever but notice the number scale. The larger number is at the bottom. Could this be a design replica of some kind of sonar screen that one would watch when exploring for oil?

It’s a interesting piece.
