This is a post I have written in my blog. The link is at the bottom here.
The best way to understand what etched glass looks like is to etch glass samples with different chems and in different ways. Then when you clean a window and reveal an etched surface, you will know what you are working with. And can explain it to your customer. The first time I was able to immitate an etched window that I was called into I was amazed. Since then I have been able to duplicate every type of etch. And I know what chems and circumstances can be used to create them. I have even etched glass for insurance companies and lawyers. Have always thought this would make for a winning demo for general contractors. Just waste it right in front of their face. Should I write an article on this?
