How it's made (PDI)
Untempered regular glass is coated in three runs in a chemical bath (sorry, but I won't share recipes). The glass is coated using a diving process and each bath is different.
At this stage preferences in regard of light transmission, glare and contrast are set.
After the glass has been coated it has to be cut to the right size with corners and edges sanded.
The tempering process is the last in the line.
Here the reflection color of the glass changes and the final product is finished.
Jack shows comparison pictures on his website where his glass has a greenish reflection and PDI is bluish. The reflective color (green, blue, purple, grey..) can be designed to the customer needs.
Jack never said that his glass is better than PDI, he only stated that it looks better to him.
As soon as the first WOZECLE's are in Germany, we will test Invisiglass in the lab.
That means that we will be able to exactly specify the reflection and transmission in % and won't use phrases like better, newer, more beautiful, sexy, modern, less expensive, stronger a.s.o.
Furthermore we should be able to tell who made it. Beside that I think Invisiglass is made in Germany too,´cause there are not many companies left who know how to coat and who own the machines.
The coating technology is not new, so there is nothing to develop for months...
just to make that clear.
