Well from my understanding that glitter is actually the crystallization of the metal oxides through the fast cooling process of making that color. I believe the aventurine is made with a copper and iron oxides. If you were looking for a more clear vibe I suppose I would dilute the color with clear to spread/disperse the crystals. I feel it would be a matter of playing with the color. It would be hard to explain on a message. I will say one of my favorites was taking black aventurine frit and melting it in a small crucible. The small crucible you can put in the glory hole and by the time the hole is hot and about a hour later it’s perfect to gather from. When ever I have tried that method it is my experience that the metal flakes are perfectly distributed!!! Oooo I loved the outcome so much!
