 The first crystals, that we are growing are copper sulfate crystals. They give an intense blue color and are quite easy to grow. For this, we need to acquire [[https://www.laborladen.de/Kupfersulfat-Pentahydrat-fein-KupferII-sulfat-CuSO4|Copper(II)-sulfate pentahydrate]]. The chemical formula is: $\ce{ CuSO4 * 5 H2O }$ The first crystals, that we are growing are copper sulfate crystals. They give an intense blue color and are quite easy to grow.
