Wicks | Cotton, Wood, Hemp | Container size, wax type, desired flame size |
Containers | Glass, Ceramic, Metal, Molds | Heat resistance, aesthetics, size, reusability |
Fragrances | Essential Oils, Fragrance Oils | Flash point, compatibility with wax, strength |
Dyes | Liquid, Block, Powder, Chips | Colorfastness, compatibility, intensity |
Additives | Vybar, Stearic Acid, UV Inhibitors | Specific benefits for opacity, hardness, etc. |
Pre-Making Calculations
Container Volume Calculation:
- For cylindrical containers: πr²h (r=radius, h=height)
- Remember to subtract 0.5-1 inch from height for safety margin
- Convert to ounces or grams based on wax density
Wax Amount Formula:
- Container volume × 0.86 (density factor for most waxes)
- Add 10% extra for spillage and testing
Fragrance Load Calculation:
- Soy wax: 6-10% of wax weight
- Paraffin: 8-12% of wax weight
- Beeswax: 3-6% of wax weight
Colorant Ratio:
- Liquid: 1-3 drops per pound of wax
- Block: 0.5-2 grams per pound of wax
- Start with less – you can always add more
Step-by-Step Candle Making Process
1. Workspace Setup
- Clean and clear all work surfaces
- Cover area with newspaper or craft paper
- Arrange all materials in order of use
- Ensure proper ventilation
- Keep fire extinguisher accessible
- Pre-heat containers if working in cool environment (optional)
2. Wick Preparation
- Select appropriate wick size for container diameter and wax type
- Cut wick 2 inches longer than container height
- Attach wick to metal sustainer (if not pre-tabbed)
- Secure wick to bottom of container using:
- Hot glue dot (wait until fully set)
- Wick sticker
- Double-sided tape
- Center wick using:
- Commercial wick centering device
- Wooden skewers and tape
- Clothespin balanced across container top
3. Wax Melting Process
- Measure exact wax amount using scale
- Break or cut wax into smaller pieces for faster melting
- Place wax in double boiler or melter
- Heat gradually, monitoring temperature constantly
- Heat to manufacturer’s recommended temperature:
- Paraffin: 180-185°F (82-85°C)
- Soy: 170-180°F (77-82°C)
- Beeswax: 160-165°F (71-74°C)
- Coconut: 150-160°F (65-71°C)
- Stir occasionally for even heating
- Remove from heat when fully melted
4. Adding Additives
- Allow wax to cool to additive-specific temperature
- Add any wax additives first (stearic acid, vybar, etc.)
- Follow manufacturer’s recommended percentages
- Stir thoroughly until completely dissolved
- Cool to fragrance-appropriate temperature:
- Paraffin: 180°F (82°C)
- Soy: 170-175°F (77-79°C)
- Beeswax: 155-160°F (68-71°C)
- Coconut: 145-150°F (63-65°C)
- Add pre-measured fragrance oil
- Stir continuously for 1-2 minutes (count 120 stirs)
- Cool to dye-appropriate temperature (usually 5-10°F cooler)
- Add colorant gradually until desired shade is achieved
- Test color by placing a drop on white paper
- Remember color will appear lighter when set
5. Pouring Technique
- Let wax cool to proper pouring temperature:
- Paraffin: 160-170°F (71-77°C)
- Soy: 120-140°F (49-60°C)
- Beeswax: 145-155°F (63-68°C)
- Coconut: 125-135°F (52-57°C)
- Pour slowly down the side of container or along wick
- Leave 1/4 inch space at top of container
- Tap sides gently to release air bubbles
- Readjust wick to center if shifted during pouring
- Cover with cardboard tent to slow cooling (optional)
- Move containers carefully to cooling area
6. Cooling Process
- Place candles in draft-free location
- Maintain room temperature between 70-75°F (21-24°C)
- Allow candles to cool completely undisturbed:
- Small containers: 4-6 hours minimum
- Medium containers: 8-12 hours
- Large containers: 24+ hours
- Resist the urge to touch or move during initial setting
- Look for even surface appearance and color
- Document cooling conditions and results
7. Second Pour (if needed)
- Check for sinkholes or uneven surface after initial cooling
- Reheat small amount of same wax mixture to pouring temperature
- Pour carefully into depressions or uneven areas
- Fill just to level of original pour
- Allow to cool completely (2-4 hours minimum)
8. Finishing Touches
- Trim wick to 1/4 inch before first burn
- Remove any wick centering devices
- Clean container exterior with alcohol wipe
- Fix minor surface imperfections with heat gun:
- Use lowest setting
- Hold 6-8 inches away
- Move continuously in circular motion
- Add labels and warning information
- Apply any decorative elements (dried flowers, twine, etc.)
- For container candles, secure lid if applicable
9. Curing
- Allow candles to cure before burning:
- Paraffin: 24-48 hours
- Soy: 3-7 days (minimum)
- Beeswax: 2-3 days
- Coconut: 3-5 days
- Store in cool, dry place during curing
- Keep away from direct sunlight
- Curing improves scent throw and burn quality
- Document cure time for quality control
Testing & Quality Assurance
Burn Test Protocol
- Conduct burn test after full cure time
- Light candle in draft-free location
- Allow to burn until melt pool reaches edge of container (1-4 hours)
- Observe and document:
- Flame height (ideal: 0.5-1 inch)
- Melt pool formation and depth
- Tunneling/mushrooming issues
- Scent throw quality
- Smoke production
- Burn time per hour of burning
- Extinguish and examine:
- Wick behavior
- Wax consumption pattern
- Container temperature
Troubleshooting Common Issues
Issue | Possible Cause | Solution |
---|---|---|
Sinkholes | Cooling too quickly | Preheat containers, cool more slowly |
Tunneling | Wick too small | Increase wick size |
Mushrooming | Wick too large | Decrease wick size or trim more frequently |
Poor scent throw | Incorrect oil %, wrong temperature | Adjust oil percentage, add at proper temp |
Frosting (white crystals) | Natural with soy wax | Add additives, adjust cooling temperature |
Uneven color | Inadequate mixing | Mix longer, add colorant at proper temperature |
Wet spots | Poor container adhesion | Preheat containers, add adhesion additive |
Cracking | Cooling too quickly | Slow cooling process, add flexible wax |
Advanced Techniques
Layered Candles
- Pour first layer and let cool until set but still slightly warm
- Create texture with fork or tool if desired
- Pour next layer at slightly lower temperature
- Repeat until all layers are complete
- Ensure each layer cools adequately between pours
Container Preparation for Adhesion
- Preheat glass containers to 100°F (38°C)
- Apply container adhesion additive for challenging containers
- Use hot glue gun for secure wick placement
- Clean containers with alcohol before pouring
Record Keeping for Replication
- Document exact measurements of all ingredients
- Record temperatures at each step
- Note ambient conditions (humidity, room temperature)
- Track cure time and burn performance
- Photograph results for reference
