Why This Skill Matters in an Emergency or Survival Situation

Creating DIY emergency candles using Altoids tins and sawdust is a valuable skill for power outages or survival situations. These candles offer a reliable source of light and warmth, and the materials are easily accessible and inexpensive. They can be made quickly and stored for long periods without deteriorating.

What You Need

Materials

  • Altoids tin or any metal tin with a lid
  • Sawdust (preferably hardwood)
  • Paraffin wax or old candle wax
  • Wick (candle wick or string)
  • Wick holder (optional)

Tools

  • Double boiler or a makeshift one using two pots
  • Spoon or stick for stirring
  • Scissors or knife
  • Pliers (optional)
  • Heat source (stove or campfire)

Step-by-Step Instructions

  1. Prepare the Sawdust: Collect sawdust from hardwood sources like oak, maple, or birch. Avoid softwoods like pine as they can produce more smoke. Crush the sawdust into a fine powder using a mortar and pestle or a blender.
  2. Melt the Wax: Set up your double boiler. If you don’t have one, use two pots, one inside the other, with water in the outer pot. Melt paraffin wax or old candle wax in the inner pot. Ensure the wax is completely melted and free of debris.
  3. Mix the Sawdust and Wax: Once the wax is melted, add sawdust gradually, stirring continuously. The ideal ratio is about 1 part sawdust to 2 parts wax. Keep stirring until the mixture is well combined and the sawdust is thoroughly saturated.
  4. Prepare the Altoids Tin: Clean the Altoids tin thoroughly. Remove the lid and place it aside. If you have a wick holder, attach it to the bottom of the tin. Otherwise, you can create a small hole in the center of the tin lid and insert the wick through it.
  5. Pour the Mixture: Carefully pour the wax-sawdust mixture into the Altoids tin. Ensure the wick is centered and submerged in the mixture. Allow the candle to cool and solidify completely.
  6. Trim the Wick: Once the candle is set, trim the wick to about 1/4 inch above the surface. This ensures a clean burn and prevents the flame from being too large.

Common Mistakes and How to Avoid Them

  • Overheating the Wax: Avoid overheating the wax as it can degrade its quality and make it harder to work with. Keep the temperature below 200°F (93°C).
  • Incorrect Ratio of Sawdust to Wax: Too much sawdust can make the candle too brittle, while too much wax can make it too soft. Stick to the recommended ratio.
  • Not Stirring Enough: Ensure the sawdust is evenly distributed in the wax. Stirring thoroughly helps in achieving a consistent texture.
  • Improper Wick Placement: A poorly placed wick can cause the candle to burn unevenly. Centering the wick is crucial for a steady flame.

Variations, Tips, and Related Techniques

  • Additives: You can add essential oils or dyes to the wax-sawdust mixture for fragrance or color. However, be cautious with the amount to avoid affecting the candle’s burn quality.
  • Alternative Wick Holders: If you don’t have a wick holder, you can use a small metal washer or a paperclip bent into a loop to hold the wick in place.
  • Multiple Wick Candles: For larger candles, consider using multiple wicks. Space them evenly apart to ensure a consistent burn.
  • Storage: Store your candles in a dry place to prevent moisture from affecting their quality. A sealed container or plastic bag can help.

TLDR

DIY emergency candles using Altoids tins and sawdust offer a reliable light source during power outages. Follow the steps carefully to ensure a consistent burn and avoid common mistakes. Additives can enhance the candles, but use them sparingly. Store candles properly to maintain their quality.
