Michael, I tint madel glass all the time with the Tamiya clear acrylics. Here's how I do it,,
Mist on your clear color coats. This will leave the clear part looking foggy. It won't look very good at first.
Then after the clear color is completely dry, give it a couple coats of regular acrylic clear. It will look better but not perfect.
Wet sand the clear with about 6000 or 8000 grit being careful not to sand through the clear to the color coats and give it another couple coats of clear.
When dry, wet sand and polish like any other clear coated paintjob.
This has worked for me for over a decade now.
Here's a pic of some I did a few years ago. As you can see they're in a "factory shade" of tint but completely clear. [I do them a bit darker now as it doesn't show up as dark in the pics as they actually are.]
