PureCrystal and Swarovski crystals can be heated to moderate temperatures, making them easy to integrate into polymer clay jewelry without damaging it, provided their specifications are respected. Non-leaf crystals can withstand temperatures of up to 350°C, while platinum-coated crystals can only withstand 160°C. For optimum results, always check the characteristics of your crystals before heating them.
When creating DIY costume jewelry, it's often advisable to fix the crystals after the polymer clay jewelry has been baked, to avoid damaging it.
However, leaving the crystal cabochon on the polymer clay during the baking process can be very useful. This allows for greater precision, maintaining the exact shape and desired imprint in the right place.
The solution? Some PureCrystal and Swarovski crystals can be heated at moderate temperatures for short periods. However, particular attention must be paid to crystal specifications to avoid damage.
| Cut crystal glass | Crystals with no unf oiled surface or translucency can withstand temperatures up to 350°C. |
| Platinum-foiled crystal | Crystals with platinum fo il (foiled) are more delicate. They can withstand temperatures of up to 160°C for a short time. Prolonged exposure can damage the protective lacquer. The protective function of the silvered mirror may alter the appearance of the crystal. |
| Crystal with surface effect or translucent | For crystals with surface effects and translucent crystals, it is not possible to specify a certain temperature, as the value differs greatly. The variation in effects and treatments applied to these crystals makes each piece unique in terms of heat tolerance. |
| Melting point of PureCrystal and Swarovski crystals | The melting point of PureCrystal or Swarovski crystals is around 1200°C, at which temperature glass becomes viscous. It is important to note that the crystal glass of these crystals is neither easily flammable nor a fire accelerant. Above the recommended temperatures, the materials do not burn, but the films and effects may be destroyed. |
You can therefore put PureCrystal or Swarovski cabochons in the oven for a short time to incorporate them into your DIY creations and make polymer clay jewelry. This simplifies the creation process, as there's no need to reposition or adjust the cabochon after firing. You can go straight to the finishing stage, such as gluing or setting.
This is the case for these original earrings or these fancy earrings.
