Polarized Organic Potassium Salt

[houstontx]

Here are some pics of a potassium salt evaporated from a water solution. I really like this salt because you seem to get a variety of shapes and patterns. Its fun as it tends to form these clusters of trapezoid/hexagonal shapes too. 2x, 10x, and 20x objectives and 533nm tint plate used. Last two images are 5 image stacks.
