Unfortunately we are limited by the colour of the bottles we receive. As yet we are unable to create streaked or mottled glass using the various colours as it requires the glass to be co-efficient which most bottle glass is not. However, we will soon be aquiring a piece of equipment that will allow us to test co-efficiency and make some really interesting sheet glass.
Very pleased to discover you! Can you tell me or show me your complete colour range for sheet glass? Is it just the blue, grees, brown and clear shown on the website? have you tried running them together to make 'streaked' or mottled sheets?
