Practical tips for

growing crystals

Safety …

… is the number one priority. Before each experiment,

always read all of the instructions. Only use materials

specified in the manual. It is pointless and quite possibly

dangerous to experiment with unknown chemicals. Do not

bring the materials you are handling into contact with

your body, particularly with your eyes or mouth.

Always wear your safety goggles when handling

chemicals! Be particularly careful with hot burners, and

don’t forget to turn them off after use!

When handling plaster, follow these safety rules:

› Do not place the materials in the mouth.

› Do not inhale dust or powder.

› Do not apply to the body.
