Epsom salts, rock salt as seeds, and iododized salt and alum

At your local grocery or drug store, you can often find common salt compounds that can be used for growing crystals. Here are a few options:

1. Table Salt (Sodium Chloride): This is the most common type of salt that you can find in any grocery store. It consists of white crystals and is often used for cooking.

2. Epsom Salt (Magnesium Sulfate): Epsom salt is another popular option for crystal growing. It is commonly used in bath salts and for soothing sore muscles. It forms clear, needle-like crystals.

3. Borax (Sodium Borate): Borax is a white mineral compound that is commonly used as a cleaning agent and laundry booster. It can form beautiful, prismatic crystals.

These salt compounds can be found in the spice or baking aisle of your grocery store or in the health and wellness section of a drug store. You may also find them available online if you prefer to order them.
