Tetka thicker than 3MM

[susanmozingo]

I can score and break 3mm Tetka without a problem. I break using either the Morton button or running pliers. If the piece of Tetka is thicker than 3MM I can't break the score. Do I need to press harder when I am scoring? Thanks.

Don't score any harder.
You will need slightly more breaking pressure for the 4mm and considerably more for the 6mm.
Get yourself these for the 6mm: http://shop.bullseyeglass.com/tools-sup ... liers.html
I'm not sure about other (cheaper) sources for those, you'll have to do some research.
