Hedef

Aşırı doygun bir çözeltiden büyük, şeffaf sekizyüzlü potasyum şap kristalleri büyütmek.

Arka Plan

Potassium alum (KAl(SO₄)₂·12H₂O) crystallizes in a beautiful octahedral habit. It is non-toxic, inexpensive, and easy to grow into large crystals. The octahedral shape reflects the cubic crystal system of alum.

Güvenlik Uyarıları

  • Use care with hot water
  • Alum is generally safe but avoid ingestion of large amounts

Beklenen Sonuçlar

Large, transparent, octahedral crystals up to 2-4 cm across after 1-2 weeks. The faces should be smooth and the crystal should be nearly colorless and transparent.

Temizlik

Alum solution can be saved for future crystal growing or disposed down the drain. Rinse beaker.
