Let's face it--crystals can be beautiful. Over the winter I have been working on the various "junk" microscopes I have and fixed up an old AO system with polarizing filters so that I could look at crystals under crossed polarizers. This is an image of urea (left over from the garden). I heated a glass slide and melted a small fragment of the urea and then placed a cover slip on the molten liquid. Rapid cooling seems to give the best crystals (IMHO). I am not sure what all I have around the house that will give results as good as this, but I figure I can start looking! For those interested, the total width of the image shown is about .7 mm.
