Which chemical looks like broken glass crystals?

Explanation:
Polyphosphate compounds often crystallize as glassy, broken fragments rather than neat, well-defined crystals. Sodium hexametaphosphate is a polyphosphate that forms long metaphosphate chains, which gives it a glassy, translucent appearance when it crystallizes. That glass-like habit helps it look like broken glass crystals. In contrast, the other salts—sodium zinc phosphate, zinc orthophosphate, and orthophosphate crystals—tend to form regular, conventional crystal shapes rather than the glassy, broken-crystal look. So the chemical that looks like broken glass crystals is sodium hexametaphosphate.
