Will the crystals grow faster if I put the jar in the sun?

Sunlight can warm the jar and sometimes speed growth a little. But warmth also creates air currents that disturb the surface. I recommend a steady, room-temperature spot for the most even crystals.

Why did my crystals become cloudy or misshapen?

Tiny impurities, too much movement, or disturbances from opening the jar can create cloudiness. Use clean tools, avoid stirring after you set up, and choose a calm spot to help crystals keep clear faces.

Are these crystals safe to taste?

They are made from sugar and are non-toxic. I avoid eating them after adding food coloring or flavor extracts. If children are involved, supervise tasting gently to avoid too much sugar.

How long will it take for large crystals to form?

Growth varies with temperature and saturation. Small crystals appear in a day or two. Larger, clear specimens may take one to two weeks. Patience rewards you with better-formed crystals.

Can I make shapes instead of straight strings?

Yes. Use a mold or a shaped support, such as a paperclip or a small twig frame, and allow crystals to form around it. They will take on the shape of the support and create more sculptural pieces.

Instructions

Warm the water slowly until it feels comfortably hot.
Stir in sugar a little at a time until the solution stays glossy and clear.
Keep adding sugar until no more dissolves and the liquid looks syrupy.
Let the mixture cool slightly, then pour it into a clean glass jar, avoiding air bubbles.
Tie a short length of string to a pencil or stick and dip the string in the solution, optionally rolling it in damp sugar for seed crystals.
Suspend the string in the middle of the jar without touching the sides and secure it.
Place the jar somewhere undisturbed at room temperature.
Watch for tiny crystal points forming each day, adding color with food coloring if desired.
After several days to a week, lift the string and admire your crystals.
Store in a dry place if keeping.

Notes

Store crystals in a dry box to prevent moisture; they can be reused for displays.
