How quickly will crystals grow?

You may see tiny crystals form within a few hours, with larger growth overnight. For the most dramatic change, allow 24 hours or more. Growth speed depends on temperature and how saturated your solution is.

Are these crystals edible?

Yes, when made with food-safe equipment and clean water, they are edible sugar. If you add non-food-safe colorants or craft materials, do not eat them. Always use clean tools if you plan to taste.

My crystals are sticky. What went wrong?

High humidity or insufficient drying causes stickiness. Place finished crystals in an airtight container with a dry packet if you have one, or dry gently in a low oven for a few minutes, watching carefully.

Can I reuse the solution?

You can dissolve the crystals back into warm water and start again, or filter and heat the syrup for a new batch. Reuse keeps the process gentle on resources.

Is boiling sugar dangerous?

Boiling sugar can burn skin. Always handle hot syrup with care. Use a long-handled spoon, keep children at a safe distance, and let an adult manage the heating steps.
