Storing candle molds

Avoiding Deformations

Deformations occur in two cases.

1) Due to Rubber Rings
Cut-open molds are sealed with rubber rings for pouring. The rubber rings should only be slipped over the mold during pouring.
Otherwise, the rubber rings will press into the mold (Figure 1). This is especially true for long storage periods.
Under certain circumstances, the rings may even be visible as indentations on the candles later during pouring. In this case, the mold has become unusable.

2) Due to incorrect storage.
The molds should be stored in such a way that the silicone does not deform. Therefore, they should be stored upright on a flat surface. Stacking them on top of each other will also lead to deformation after a long period of time.

Storage recommendations:
Basically, there are two types of molds: flat molds and tall, round molds. Flat molds should be stored on a flat surface so that they are fully supported (correct: Image 2, incorrect: Image 3).

Round candles should be stored upright. If the opening is at the bottom, dust cannot enter (correct storage in Image 4). If round candles are stored lying down for an extended period, they will become oval. A cast candle will then no longer be round (incorrect storage in Image 5).

If molds are not needed for months, they should be stored in a cool (no risk of frost), dry place. It is recommended to pack the molds in a dust-free manner.
We wrap the cleaned molds in paper towels (Images 6 and 7). The paper towels can be secured with adhesive strips. Using a waterproof pen, you can now write on the adhesive strips and label the wrapped mold (Image 7). Alternatively, you can also attach labels. Molds should not be stored in foil or plastic bags.
