Review on Novacan Old Masters Flux Oz by Chris Wheeler

This is a review of NOVOCAN BLACK PATINA, not flux (which is sub-par - get Glastar). It would be very nice to know that Novocan Black Patina will spoil/eat the color of the rainbow on the stained glass windows. It is not listed anywhere on the bottle and I have not been able to find this information anywhere on the internet except for a specialized site that lists it in the product information. I had to search for information. Why? Because I spent over 40 hours with the stained glass pane, applying the patina like I would any other item, washing it and noting that the edges of every single piece of iridescent glass had turned a dull silver color. My work, which I spent a tedious week of my life creating, was spoiled in 15 minutes. THANK YOU FOR NOTHING, NOVOKAN. Please put such important information on the packaging!
