How long do the crystals take to form?

Most pieces show visible growth within 12 to 48 hours. Full drying and firming may take several days. Patience rewards with denser crystals and clearer colors.

Are the crystals safe to touch or handle?

The crystals feel dry and slightly grainy when mature. They contain no harmful chemicals in normal household use, but do not eat them. Keep them out of reach of small children and pets to avoid accidental tasting.

What if the solution does not form crystals?

Try a slightly warmer water and add a bit more baking soda until the solution thickens. Ensure the jar sits still and evaporation can proceed. If you still see little change, try a test with a small amount of Epsom salt to compare growth.

Can I use liquid watercolors instead of food coloring?

Yes, liquid watercolors work well and often disperse more evenly. They give clear hues without affecting the solution much. Start with a drop or two; a little color goes a long way.

How do I clean up spills or stains from food coloring?

Act quickly with warm water and a mild detergent. Blot rather than rub to lift dye from porous surfaces. Wear an apron if you prefer and lay down paper towels on your workspace.
