Crystallization of copper sulfate pentahydrate

Copper sulfateCopper sulfate

During my first and second semesters at university, I had some extra time at the lab. With the lab assistants' blessing, I grew some copper sulfate crystals. My first crystals turned out somewhat pitiful, but after learning from my mistakes, my second attempt used a slow grow method that gave far better results. After coating the crystals with nail polish, I was able to take them home and decorate my room.
