The Gold and Silver Galaxy series is made by adding 99.99% pure gold, silver and platinum to hot Borosilicate (hard) glass. At just the right temperature, these precious metals transform into a gas resulting in bright and vibrant colors. Each uniquely handcrafted Internal Fire Glass marble is a visual escape in the palm of your hand.
