Glass moulds are great for votive candles, but can be fragile
Glass moulds are a great option for creating votive candles, as the glass becomes part of the final product. They are easy to clean and reuse, and they showcase the candle's colour and layers. Glass moulds also allow you to see the candle as it forms, which can be aesthetically pleasing. They are made from laboratory-grade heatproof glass and produce flawless candles.
However, glass moulds can be fragile, and special care must be taken during the candle-making process. For instance, it is important to prepare the glass properly before pouring in the wax. Additionally, to remove the candle from the mould, it is recommended to rinse the mould with soapy water, shake off the excess drops, or spray it with silicone. Warm the mould gently with a fan heater, and ensure the wick is centred and supported a few centimetres above the mould.
When it comes to releasing the candle, leave it in the mould until it is quite cool, then gently pull on the wick. If the candle still won't come out, try placing the mould in the fridge for 20 minutes or running it under hot water to loosen the wax.
Glass moulds offer a unique and elegant way to create votive candles, but their fragile nature requires extra care and attention during the candle-making process to ensure successful results.
