The shape of your crystal depends on what type of salt you used. Coat the surface of the crystal with a lacquer. To protect the crystal from being destroyed by exposure to moisture, cover the crystal with a coat of lacquer. Use a brush to apply an even coat over the entire surface.You can also try coating the surface with a layer of nail polish to protect it.
But using my setup, it’s very rare for the solution to evaporate so quickly, so there’s a high chance you won’t need to add any solution at all. The purpose of the water is to bring the saturation down and to dissolve any tiny particles in the solution. Once no more tiny crystals are present, as you leave it to evaporate, bigger crystals should form.
Growing Epsom salt crystals
Pour in about ¼–½ cup (60–120mL) of your salt and stir until the water is clear. If you don't see any salt grains in the water, stir in another spoonful. Keep stirring in more salt until you see salt grains that won't dissolve when you stir.You've just made a supersaturated solution. This means the solution contains more salt than water can usually hold! When you heated the solution , the molecules sped up, creating space between them that allowed more of the solute to be absorbed than usual.
You might be able to serve some ketchup in them. Once, I tried to pick up a pyramid with my tweezers, but by accident, it fell back into the solution. Instead of sinking, it continued to float – but with the tip of the pyramid facing up, and the base facing down.

Although sodium chloride theoretically crystallizes as cubes, the crystals grown with my procedure look a little flatter on the side facing up. This is a limitation to growing them on the bottom of the container, because each crystal face grows at a different rate. Hopper salt crystal pyramids that I managed to grow. These are very different from the crystals that are the subject of this guide. Now, transfer a little solution to the container of your choice, making sure it is dry beforehand. With a pair of tweezers, very gently transfer the seed crystal from the dish to your new container.
If you’re already familiar with MAP, then we’re sure that you’ll already be well aware that it is more of a salt than a powder. For that reason, you’re going to find that it will be able to dissolve extremely easily when it is placed in water. These crystals are surprisingly tough for home grown crystals. The bottom one, which is similar in size, took just 2 days to grow. As a result, its crystal structure contains lots of defects, causing it to be less transparent.
How to make pyramid salt crystals
Crystals made from plain table salt were the least successful for us. Apparently the iodine in table salt can prevent the crystals from growing properly. Here are some important terms that you need to know before understanding the science behind salt crystals. Now we need to place the plates in sunlight. The entire process of salt crystal formation will take about 3 to 4 days, depending upon the room temperature and availability of sunlight. Since we targeted to create crystals to make Christmas ornaments – we made a Christmas tree, star, and snowman.
If salt crystals won't grow, try refrigerating the salt water. Another "trick" is adding a few grains of salt to the liquid too get the action started. But, if these grains immediately dissolve, the solution just is not saturated.
The key is to add an ingredient called potassium alum. Alum calms the surface and helps the pyramids form. It is normally used in baking and pickling.
But you can actually grow them much faster. By now, the weight of the crystal should start to strain the fishing line. Don’t remove them from solution too often to take a look – the line might snap or slip out of the crystal. This happened to two of my crystals, and I had to stop growing them early. At this point, lots of smaller crystals will have formed at the bottom of the jar.
Sit the jar on your counter overnight to allow time for the crystals to grow. While small crystals will grow within a few hours, large crystals will take longer. Great, my stepsons are over this weekend and I haven’t anything got anything handy for us to do as a team. Your step by step process will make crystal growing our family time.
They cannot be moved – attempting it will cause salt dust to form, failing the run. So it must form, grow and be harvested from the same container. During crystal growth, the weather might suddenly get very hot – or it might rain a lot.
Use your scoop to break up lumps before using, or shake the jar often. If you do not own Epsom salt, then use sea salt as a replacement. Making DIY crystals at home is an excellent way to introduce your children to the incredible possibilities of science. Experiments like this one can spark their curiosity and make them eager to learn about the world around them.
Make sure you use a disposable one, since the food coloring and alum can change the color of the container. I have been trying to grow pyramid salt crystals for a very long time, and I’m glad to share what I’ve learnt with you. Before you remove the second pyramid, dip the tweezers in a cup of water. This step ensures that there are no powdery salt grains sticking to your tweezers – which will cause thousands of tiny crystals to form in the dish. Now, it’s easy to make regular salt crystals at home.
