Thanks. That one is about 12" tall. I called them the Ribbon series. The ribbons are made from a bundle of glass "overlay canes". I normally used 7 canes in the bundle, heated it up and would twist & stretch the bundle as I randomly draped it around the main colored core. There's a thin layer of silver foil under the ribbon which I'd wrinkle & overlap the sheets to add depth & visual texture, the silver sheets are 4x4" square that are turned diagonally so the corners create tips, which look like mountain tops behind the ribbons.
It's similar to how paperweights have decorations applied in layers, so they appear to float. The "trick" is to coat all the colors with a layer of clear, so none of the colors actually touch each other.
The "overlay canes" are made in a similar way. First I coat a core of clear glass with a layer of opaque white glass, then add a layer of gold glass, and finally a layer of clear glass. Then that gets stretched out, like taffy, into a long "cane". After the cane cools I cut it up into short lengths, about 3" long, and reheat 7 of them together to make the ribbon. The opaque white inside gets super thin so it becomes translucent.
After applying the decorations, I dip the piece into the furnace of glass again to encase the decorations, and while the last gather is still molten I pull it down towards the base so the base has an extra thick layer of clear glass.
Here's a cobalt one. It's about 15" tall.
