Pros : Loved the bright colors and patterns. Especially liked in the tie die funky. Made some fantastic pendants with it. I wanted to rush out and purchase more after I saw how vibrant the colors were when I took them out of the kiln. I think they are even brighter then other dirchoic glass.
Cons : The only bad thing I have to say and it really isn't bad is that the glass was unpredictable in the kiln. I had to increase the temperature & length of the soak to make it fuse with the 90 base glass. Also, some of the coatings crinkled a lot and others not so much. Overall you will find it crinkles a lot more than other dichro. I preferred not capping the glass with clear.
Other Thoughts : Would definitely recommend this sample pack if you are bored working with other dichro out there and you want to try something new in your jewellery pieces. You can make a lot out of the 12 pcs. you receive.
