How To Make Crystal [better] [VERIFIED]

| Mistake | Why | Fix | |--------|-----|-----| | No crystals | Solution not saturated | Add more solute until some remains undissolved | | Many small clumps | Too much dust / too fast cooling | Filter solution, cool slowly | | Crystals on jar walls | Vibration or rough glass | Move jar gently, clean glass well | | Cloudy crystals | Fast growth or impurities | Grow slowly, use distilled water |
