When you need some shattered blue glass for something you are working on:

1. Real hammer. The nut hammer will not work. 
2. Wear safety glasses, gloves. 
3. Try to remember to do it outside in a rusty old bucket with leftover dried sunflower dream petals in the bottom.  

 

 This is where this creation is so far. I need some glue. Gorilla glue will do, I think.

 

Yup, gorilla glue is what I need now.
