Question: can pva glue be used on glass?
Answer: Instruction: take a bit of PVA-glue (regular Casco "wood-glue") in a glass, add a bit of water (3x PVA amount). Whip around with a paint brush and then paint the glass. Will be tricky to get the watery glue float out, perhaps due to surface tension, I will try to add some detergent next time.. Let it dry.
