Step 1: Necessary supplies
Also, collected some fresh flower petals from the garden, which I will use to embed in the shells.
Then, the wax - here I used semi-refined paraffin wax for the base and the shells. No additives.
Step 2: The base
Melt the paraffin wax in a double boiler. Do not add any additives which will make the candle opaque. Though the plain wax looks like white, it is colorless and transparent.
The mold needs a releasing agent. You can use a Silicone spray, if available, otherwise applying a coat of coconut oil mixed with paint thinner will do the same and make it easier to take out the cooled wax cast from the mold.
Pour the melted wax in the mold and allow it to cool. Make relief holes and re-pour if required
Take out cooled wax base from the mold and keep aside.
Step 3: The Shells: Flower Petal Embedded Luminaries
Apply mold release in the mold.
Melt the wax in a Double Boiler, and pour a thin layer in the mold. You can rotate the molten wax in the mold. to form a thin layer of equal thickness.
Lay the flower petals over this thin layer. Press the petals lightly with your fingers to make them stick to the wax.
Pour molten wax over the flower petals and slowly rotate the mold with your hand to form a uniform layer completely covering the petals. pour out the extra wax.
When the shell is cooled, take out from the mold. Make three numbers of these shells.
