Use liquid food coloring to dye your solution. Note that Borax takes color very well, while Alum crystals often stay clear with just a tint of color on the surface.
Here is everything you need to know about the science, the methods, and the best recipes for making stunning homemade crystals. The Science: How It Works home made crystals
Tie the seed to a fine nylon fishing line (cotton string acts as a wick, creating false nucleation). Prepare a fresh, filtered supersaturated solution in a clean jar. Hang the seed so it is fully submerged but not touching the sides or bottom. Cover the jar with a coffee filter (to keep out dust, which acts as false nuclei) and place it somewhere vibration-free. As solvent evaporates, the seed will grow—sometimes by millimeters per day. Use liquid food coloring to dye your solution
So boil a pot of water. Stir in a cup of borax. And wait. The geometry is already there, hidden in the liquid, waiting to remember itself. The Science: How It Works Tie the seed
Make a fresh batch of supersaturated alum solution. Let it cool slightly, then submerge your seed crystal. Over the next few days, the seed will "pull" the alum from the water, growing into a large, transparent geometric diamond shape. Method 3: Sugar Crystals (Rock Candy)
Heat the water and sugar until the solution is completely clear and syrupy.
