How To Make A Coal Garden

Coal Garden After 4 Hours

Colorful Coal Garden

A Coal Garden is easy to do, and no two will be the same. They are similar to those little crystals that you dropped in water and they grew into colorful spiked creations.


One lump or several chips and pieces of coal

A shallow pan or plate with a ridge

2 to 3 good sized lumps of coal

A small amount of water for the bottom of the holder


6 Tablespoons of salt

6 Tablespoons of bluing (you can get it in your grocery store)

6 Tablespoons Water

1 Tablespoon ammonia

Slowly pour the bluing, water, and ammonia mixture over the coals.

If there are any bare spots, sprinkle ammonia on them.

Add drops of different food coloring here and there.

Add a little water to the pan if it becomes dry.

Adding twigs found outside in your yard or garden can make your coal garden have a touch of nature.

NOTE: Do not let children do this by themselves. Ammonia is very strong and can burn nostrils and lungs, so be sure there is adequate ventilation or do this outside.

Look like fun.

Question: "6 tablespoons of 'sale'"--does that mean "6 tablespoons of 'salt?'"

Yes, you are right - it should be "salt" instead of "sale." I'm sorry - that will be corrected! Thanks for pointing that out to my attention.

Great activity for grandparents and grandkids! Brings back memories of when I was a kid....except coal was much easier to find back then! What properties in the coal make it grow? Would any other rocks or minerals work?
