Pros : Van Gogh is a specialty glass to say the least. I used it for mosaic work as well as foil and solder. It produces a beautiful project either way especially with light behind it. It is also easy to cut. No matching due to the random pattern.
Cons : Lovely glass but takes a lot of extra work due to the thin backing. It is like working with mirror glass. The black backing chips and scratches badly when grinding. Must be sealed for lead or foil and solder work.
Other Thoughts : I will probably use Van Gogh again due to the uniqueness of the glass even though it is somewhat of a pain to work with.
