Get purple alum crystal: https://www.etsy.com/listing/4319881335/home-grown-purple-alum-crystal I spent over 7 months growing this purple crystal, and it's one of the nicest I've ever grown. It's made of a combination of potassium alum, which is white, and chrome alum which gives it its characteristic purple color. The higher the ratio of chrome alum to potassium alum, the darker the crystal. --- MATERIALS I bought my materials in Malaysia, but the items below are similar ones available on Amazon — they work just as well if you’d like to try this experiment yourself. • Regular alum: https://amzn.to/47WEog4 • Chrome alum: https://www.sciencecompany.com/Chromium-Potassium-Sulfate-100g-P16503 • Electric burner: https://amzn.to/47MeHi8 • Nylon fishing line (clear, 0.14 mm): https://amzn.to/3XlgZjo • 600 mL beaker: https://amzn.to/4qUgH0l • Plastic petri dish (90 × 15 mm): https://amzn.to/4r05jjS • Plastic funnel: https://amzn.to/43oCcMQ • Filter papers: https://amzn.to/49gpymY • Precision tweezers: https://amzn.to/47AS0yB • Digital scale: https://amzn.to/4olYTsy These are Amazon affiliate links — I may earn a small commission if you purchase through them, at no extra cost to you.
