Pros : This mold makes delightful little centers that really bring an added dimension to the flowers.
Cons : The molded glass is difficult to remove from the mold. I find I need to tap around the glass (sometimes quite vigorously) to release it, and eventually the molds break. Although I did get a dozen or so firings from them. The large cone doesn't seem to have this problem.
Other Thoughts : Perhaps if the mold material was thicker in the cone it wouldn't be as fragile.
