Interesting physics to know.

Most of the places that care about the clear ice around where I live purchase pre-frozen cubes or spheres.

They come from the vendor with each one individually vacuum sealed in a long strip. Cut one off the strip, open it, and slip it into the glass.

Probably not worth the labor to produce the cubes themselves when there is a simple, deliverable, solution available.

Pretty great video about a company that makes ice for bars in NYC
