Nice crystals

Post by Robert Berdan »

Nice crystals. I have played with Urea as melts and from solutions and my samples looked very different. It is amazing how small changes to the solvent, drying condition or additions to the solution can change the shape of the crystals. Even in a single batch I see a lot of variation.

Nice photos.
