Sorry for the delay in responding. My wife an I have been communig with the fish (scuba) for the last 2 weeks.
The elements you see are made with my concoction of glass clay. They may or may not be freeze ‘n fused depending on the shape and configuration. I have basic information in my glass clay tutorial on my site. I do need to upgrade the tute for the elements. My object initially was to make very small elements with great detail I accomplished that, but in doing so I have found another fascinating way to create ad hoc (without molds) detailed elements. Once that is perfected I will rework my tute.
