Pros : These will save me time and effort when I need to make a bunch of uniform items or my upcoming workshop with several inexperienced glass artists who will be decorating with frit and accessory glass or enamel painting.
Cons : I wish they had 3 inch, these are heavy and large for my planned ornaments.
Other Thoughts : I have concerns about the edges being cloudy when fired, while not sharp, they aren't exactly smooth.
