- Creating high quality candles requires controlled and consistent wax temperature for both the first and second pours. Uneven wax temperature and inferior control causes blending and sinking issues.
- Do not get any water in the wax as it causes wicks to flicker, sputter, and spatter and will cause pits in the candle surface.
- Consistently applying uniform even heat to the wax is essential. A water jacket melter depends on maintaining the water level for even heating and requires constant monitoring. When the water level drops during operation, it no longer heats evenly.
- The heating element in a water jacket will burn out and fail when the water level is too low to protect it.
- Water jacket melters are not insulated, which increases energy costs (For example, if the water heater in homes was not insulated the energy costs would nearly double).
- Wax takes on a chemical fuel-like smell if over-heated and no fragrance will cover up the foul odor. Overheating also causes discoloration, cracking, poor fragrance throw, poor glass adhesion, frosting, rough tops, and weakens the finished product.
- Look for a waterless insulated solution that will apply a reliable uniform blanket of controlled heat to the wax to consistently produce high quality candles.
Select heating equipment that provides an even distribution of heat with tight temperature control to prevent overheating, which oxidizes some of the raw materials used in pattern waxes, causing the wax to be brittle or rubbery. The appearance of the wax in its molten state can indicate when the wax is overheated. Some indicators include:
- Color change
- Black specs within the molten wax, and on the bottom of the tank and walls
- A translucent look to filled wax, showing signs of filler fallout
- Smoke or vapors emitted from the wax
Four Ways to Prevent Paraffin in Crude Oil:
- Wax build-up occurs as crude passes through cold pipes and conduits. Control these arterial blockage problems by finding an insulated heated product that can be wrapped around the pipe.
- As the wax thickness increases, pressure drop across the pipe needs to be increased to maintain a constant flow rate. Keep your power requirements low and stable by keeping the pipe temperature above the cloud point with a product that will both heat and insulate.
- Avoid excessive pigging and hot oiling costs by finding a solution that prevents wax build up by evenly heating the entire outer surface area of the pipe.
- Eliminate production shutdowns and extensive workovers by finding a reliable heating solution that prevents wax blockages
