In an effort to one up those posting polarized chemicals with long names here is a contender: a mixture of a proprietary carboxylate salt, sodium phosphate, N,N-Diethyl-p-Phenylenediamine salt, and Ethylenediaminetetraacetic Acid Disodium Salt.

Polarized Organic Potassium Salt

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 ima...
