I love this half-and-half teardrop! It was the very last drop made from this glass, and I had attached the last of the Storm glass to another strip so that I could use every last bit. This last drop got a bit mixed where the two colors of glass were melted together. The bottom half is the swirling of Storm, but then it morphs into High Tide - which makes a lovely pairing with dark Teal.
Okay, maybe I should back up in my explanation. When I'm out melting glass into teardrops with focused sunlight and my giant magnifying glass, I use long strips of glass - either cut from the side of a bottle, or a sheet or rod of stained glass. I hold one end of the strip in my hand, and slowly melt drops off the other end, one by one.
When the strip has melted down to around 4 inches, my fingers start getting a bit toasty, and I have to stop. But I don't want to waste the rest of the glass! So, I get another strip of the same color, melt them end-to-end to make a single long strip of glass, and then I can keep going.
But, with limited edition colors, they're often limited edition simply because that's all the glass I have in that color. I still don't want to waste that last 4 inches of glass - in fact, I want to get every drop I can out of the glass I have! So instead I'll melt the tail end onto another color. (Sometimes this works, sometimes it just breaks apart at the join if the two types of glass have melting points or cooling rates that are too different. But I always try!)
This often results in one or two drops that are half and half. Sometimes they're gorgeous and impossible to replicate, and sometimes it just looks weird and gets thrown in the bag of one-off drops that may or may not ever get used in some later projects.
Personally, I think this one turned out gorgeous, and I love the pairing with tiny teal teardrops!
