Here's a great idea for an attractive centerpiece for any special occasion or time of year. Floating candles are a great beginner project, and with a nice glass bowl and some clear or colored stones, you'll have a simple but elegant display.
When the wax cools to 180 degrees, carefully pour colored and fragranced wax into the tart molds. Try to pour right to the top because there will be a small amount of shrinkage when the wax cools.
Place a LX 12 wick assembly in the center of each mold. (Remember not to use a wick stickum because the candle will need to release from the mold when it cools.) You can use a bamboo skewer to re-center the wick if it moves. Let cool overnight and remove from molds.
Place clear or colored stones in the bottom of the glass bowl. Add water and floater candles. They will need room to move, so it's important not to add too many.
