After opening the lead box containing the mineral samples, Richard's expression beneath the protective suit's mask became serious, and he quickly got to work.
First, he took a sample and placed it in a large blue container, adding prepared alkaline solution to it. Letting it react to remove impurities and obtain a relatively pure sample. Then he added various liquids in turn, allowing them to react until a white precipitate formed in the light green liquid, at which point he stopped.
Afterward, Richard took another sample, this time placing it in a large green container, adding prepared acid liquid to it to react and remove impurities. Then the product was filtered, crystallized, and reacted with various liquids until a brown flocculent was produced before stopping.
