Creating a 300-hour emergency candle requires selecting the right wick, choosing suitable fats or oils, and using a sturdy container to ensure safety and efficiency.

Choosing the Right Wick

The wick is a crucial part of an emergency candle. Cotton string is an excellent choice due to its effectiveness in burning steadily and safely.

Wick Types:

  • Store-bought wicks: These are pre-waxed and ready to use.
  • Homemade cotton string wicks: These can be easily made by soaking cotton string in salt and boric acid solution.

The wick's thickness should match the candle's size. A thicker candle needs a thicker wick to burn correctly. Avoid wicks that are too thin, as they might not burn through the entire candle.

Selecting the Correct Fat or Oil

The fuel for the candle can be various types of fats or oils found in many homes.

Common choices:

  • Crisco (vegetable shortening): Popular for its long-lasting burn.
  • Vegetable oil: A common household item that can serve as fuel.

Other options:

  • Animal fats like lard or tallow can also be used but may not be as readily available or convenient.

Ensure the fat or oil is evenly distributed around the wick. This balance helps to achieve a consistent burn rate and extends the life of the candle.

The Role of a Sturdy Container

The container is essential for the safety and stability of the candle.

Suitable containers:

  3. Tie a small weight to one end of the wick, ensuring it stays submerged.

You want the wick to extend above the shortening or oil by about half an inch.

Securing the Wick in Place

Securing the wick prevents it from moving around while you’re pouring the fuel. Tape the top of the wick to a stick or pencil, resting it across the top of the container.

Here’s how:

  1. Place the stick/pencil horizontally across the container's opening.
  2. Position the wick in the center, taped to the stick/pencil.
  3. Ensure the wick stays straight and centered.

This setup helps the wick stay upright once the shortening is added.

Filling the Container with Shortening or Oil

Next, prepare the container with the fuel. Crisco shortening is a popular choice because it is solid at room temperature and burns well.

Steps to follow:

  1. Spoon Crisco shortening into the container, packing it down tightly.
  2. Ensure the wick remains centered.
  3. Fill the container up to about an inch below the rim.

Alternatively, you can use liquid oils, but they must be solidified by placing the container in the refrigerator after filling.

Finalizing the Construction

Once the container is filled and the wick is secure, it's time to finalize the construction. Let the shortening or oil firm up if it’s not solid yet.

Final Steps:

  • Adjust the wick so only half an inch protrudes above the surface.
  • Ensure the fuel around the wick is smooth and even.
  • If necessary, place the container in a cool place to solidify the fuel fully.

After this, your 300-hour candle is ready for use. It’s a convenient, long-lasting light source perfect for emergencies or long-term usage.
