I noticed, in the cheap instant coffee, there are some rare crystals of the instant powder that have sharp, glassy attributes.
I assume that, in the manufacture conditions of the instant powder, there are a subset of conditions that produce these other crystals. How about changing the conditions to
produce the coffee powder as all of these crystals. A glassy heaped teaspoon, caffeine hit.
There is probably going to be problems with dissolving speed so won't be for the boil, splash and dash market. This could possibly made into cubes for hotel breakfast tables next to the hot water jug.
One lump or two? Just another tiny choice on the path to the point of infinite choice.

So the small number shiny crystals must be a subset of that freezing process, too many water molecules, crystallized on a spray nozzle, as none of the coffee substances shown have a glassy substance. Probably not the desired so chosen against, but could be. |

Chucking another variable at it, I wonder, if spray drying in a strong, cold, magnetic field would make glassy crystal caffeine. Good to drink but Xray quality. |

I've noticed a fine powdery sediment (as found
when you
make fresh coffee the way I do, but somewhat finer & a lot
less of it) in
some brands of instant coffee of late that didn't use to be
there before, I'm guessing they're
throwing a little bit of ordinary ground coffee bean in with
the instant product for flavour or something, might your
little
glassy
bits be anything to do with that? |

^Don't imagine so. The glassy bits seem to be still instant coffee, a bit like the difference between Obsidian and Granite. |
