Are these crystals safe to handle?

Handle them with care. When fully dry and sealed they feel stable, but loose fragments can flake. Keep them away from children who might put small pieces in their mouths.

How long does crystal growth take?

You will see initial formation within a few hours. For fuller coverage you may need to wait 12 to 48 hours. The exact time varies with temperature and concentration.

Can I dye the crystals bright colors?

You can add dye, but bright colors sometimes mask the delicate crystalline light. I prefer pale washes for a softer, more luminous look.

Can I reuse the solution to grow more hearts?

You can sometimes use the leftover solution once, but its effectiveness decreases. Fresh, hot solution gives more predictable results.

What happens if my crystals crack or fall off?

Crystals can chip if bumped. If pieces fall, you can re-melt and re-grow on the same frame or conserve the fragments in a shadow box. Treat breakage as part of the object's living history.

Borax powder (or another crystal-growing agent)
Hot water (just off-boil)
Small glass jars or heatproof bowls
Heart-shaped pipe cleaners or small cookie cutters (optional)
String or thin twine for suspending shapes

Cook Mode Prevent your screen from going dark

Instructions

Prepare a calm workspace and set out a soft towel.
Keep water nearby and ensure good ventilation.
Heat water until very warm but not actively boiling.
Measure borax and stir into the hot water slowly (about three tablespoons per cup).
Shape your hearts with pipe cleaners or cookie cutters.
Tie a length of string to each heart for suspending.
Pour the hot borax solution into jars until they are half full.
Suspend the hearts in the jars without touching the sides.
Cover the jars with a soft cloth to keep dust out.
Check periodically and watch how crystals gather.
When crystals reach the desired size, remove the hearts carefully.
Rinse the finished hearts with cool water to remove residue.
Optionally seal the hearts with a light spray of clear sealant.
Label the date and note any color or scent.

Notes

Borax dissolves well and encourages visible crystal formation. Handle with care, especially around children and pets. Consider alternative recipes if preferred.
