growing crystals

We did some crystal growing experiments. These crystals are Magnesium Sulphate (Epsom Salts) By mixing the packaged Magnesium Sulphate with water and allowing the solution to dry over a period of 2 weeks, we grew these crystals.This is another photo of the Magnesium Sulphate crystals.
We also used Sodium Chloride (table salt) to grow crystals. The next 2 photos demonstrate the growth of sodium chloride crystals. Notice the difference in texture!

These crystals grew in a different shape than the magnesium sulphate crystals. The sodium chloride crystals were smaller. They also were more defined. The magnesium sulphate crystals reminded me of the shape that quartz and amethyst grow in.
