Moulds
The moulds used for pouring should be clean and at least at room temperature; it is advisable to preheat them.
Colourants
Most colourants work well with Kerawax 4600 paraffin. When using powder colourants, heat the wax to 80°C, add the dye, and mix until dissolved. Powder dyes can also be dissolved in fragrance and then added to the melted wax. For powder dyes dissolved in fragrance, liquid dyes, granules, or when not using dye, heat the wax to 70°C. If you want to make a darker candle, add a small amount of black dye to the colour you are using.
Fragrance
Kerawax 4600 can be used with almost any fragrance up to 10-12%. The size and depth of the burn pool greatly affect scent throw, so selecting the proper wick is essential.
Wick Selection
Kerawax 4600 may require larger wicks than traditional paraffin waxes. They tend to burn more downward than outward, allowing for longer burn periods. The fragrance, colour, and design of the candle significantly impact the best wick choice. A too-large wick can cause sooting and accelerated burn times. If you experience poor flame quality or stability, try a different type of wick. Test burn after the candle has rested for 48 hours post-pouring.
Melting
Heat the wax to 70°C. When using powder dyes, heat the wax to 90°C, add the dye, and mix until dissolved. Undissolved powder dyes will appear as dark specks at the bottom of the mixing container. Temporary high temperatures such as 90°C have no adverse effect as long as the wax is quickly cooled back down. Higher temperatures may cause the wax to discolour. Let the wax cool to your desired pouring temperature, add the fragrance, and mix well. Ensure you stir the wax regularly while melting. Avoid using containers containing copper and zinc as these can accelerate discolouration; stainless steel is the best choice. Digital thermometers are also helpful tools that make the candle-making process easier.
Pouring
The appropriate pouring temperature can vary depending on the mould type and size, as well as the fragrance and dye used. It is advisable to pour the wax into preheated moulds.
Double-Pour
When using Kerawax 4600, two pours are required for larger candles, such as 8-10 cm pillars. Perform the first pour at 65°C, filling the mould to the top, and let it cool until it is still warm but solidified in the centre, with no liquid. If the top of the mould (the bottom of the candle) has hardened and left a cavity, poke two holes near the wick and pour a second time at 60°C.
Cooling and Releasing Candles from Moulds
Cool the candles undisturbed at room temperature (about 25°C). The moulds should not be too close to each other to allow air circulation for even cooling. Kerawax 4600 wax is easy to remove from the moulds, but if the candle is difficult to remove, place it in the refrigerator for a few minutes and then try again. Let the candles rest undisturbed for 48 hours before burning.
