this is my new favourite lamp, just incredible detail
it seems one swirl goes in one direction on outer part of the globe and the other swirl goes in the opposite direction on the inner part of the globe, would this make it like a helix?

I also read somewhere that some of the old hand-blown pieces sometimes have tiny pieces of charcoal inside them as that is what they used as fuel to make the glass hot, there are tiny areas in the globe with black residue.
it was a pendant when I bought it but might look better as a table lamp? I will set it up soon both ways with the lamp on to see.
it is about 10 x 10 inches (25 x 25 cm)
