Book 27, Question 50
What are the secrets to growing a great crystal?
Use clean containers, pure ingredients, and a good seed.
Keep the setup still, away from drafts and bumps. Make changes slowly, such as letting water evaporate over days. Be patient, because rushing leads to cloudy clumps. Take notes on what you tried and how it looked. Like any science project, trying the same thing again with one small change teaches the most.
