Candle making involves hot liquids, chemicals, and open flames. Please read this disclaimer carefully before using our calculator or following any of our guides.
1. Estimates Only
All calculator results are estimates based on average wax density values and standard formulas. Actual results vary by wax brand, batch, ambient temperature, and other factors. Always weigh your ingredients with a digital scale accurate to 0.1g rather than relying solely on calculated values.
2. Not Professional Advice
The content on this website is for educational purposes only. It does not constitute professional, scientific, chemical, or safety advice. We are candle making enthusiasts sharing our experience, not certified chemists or safety engineers.
3. Follow Manufacturer Guidelines
Always follow the manufacturer's instructions for your specific wax, fragrance oils, dyes, and wicks. Recommended pouring temperatures, maximum fragrance loads, and wick sizes vary by product. Manufacturer data sheets take precedence over any general guidance on this site.
4. Chemical Safety
Fragrance oils and other candle making additives are chemicals that require careful handling:
- Flash points: Every fragrance oil has a flash point — the temperature at which it can ignite. Never heat fragrance oil above its flash point. Check the Safety Data Sheet (SDS) for each product you use.
- Temperature control: Add fragrance at the temperature recommended by your wax manufacturer (typically 180-185°F / 82-85°C for most soy waxes). Too hot and the fragrance evaporates or degrades; too cool and it won't bind.
- Skin contact: Some fragrance oils can cause skin irritation. Avoid direct skin contact with concentrated fragrance oils.
5. Ventilation & PPE
Always work in a well-ventilated area when melting wax and adding fragrance. Wear appropriate personal protective equipment (PPE): heat-resistant gloves when handling hot wax, and consider eye protection when working with fragrance oils.
6. Fire Safety
Candles are open flames. Basic fire safety rules apply at all times:
- Never leave a burning candle unattended
- Keep candles away from flammable materials, children, and pets
- Place candles on stable, heat-resistant surfaces
- Do not burn candles for more than 4 hours at a time
- Keep a fire extinguisher accessible in your workspace
- Never use water to extinguish a wax fire — use a fire extinguisher or smother with a lid
7. Regulatory Compliance
If you sell candles, you must comply with applicable regulations. In the United States, this includes ASTM F2417 (Standard Specification for Fire Safety for Candles) and Consumer Product Safety Commission (CPSC) requirements. Requirements vary by country and jurisdiction. It is your responsibility to research and follow all applicable laws.
8. Parental Supervision
Candle making should only be performed by adults or under direct adult supervision. The hot wax, open flames, and chemical materials involved make this an activity unsuitable for unsupervised minors under 18.
9. Limitation of Liability
CandleCalc and its contributors shall not be liable for any damages, injuries, losses, or expenses arising from the use of our calculator, articles, or any information on this website. You use all information at your own risk. By using this website, you acknowledge that candle making carries inherent risks and accept full responsibility for your actions.
