COMMUNITY ENGAGEMENT

Legacy Community Development Programs

When we began working in Colombia in the 1980s, many rural communities did not have reliable electricity and cooked their daily meals over an open fire. In many traditional communities, this method of cooking—balancing a pot over three stones placed above a wood fire—consumes large quantities of firewood and produces significant amounts of smoke. With repeated exposure, this smoke often irritates the eyes and lungs. For campesinos living in rural areas without electricity, open-fire cooking was the only available option.

Discovering the Binde

In an effort to reduce the amount of firewood consumed in daily cooking, our team began searching for alternatives. In this search, we learned about the binde, a small traditional cookstove originally made from termite mounds. Campesinos who used bindes reported that they burned far less fuel than an open fire.

However, the traditional method had drawbacks. Locating a termite mound required traveling into the forest, transporting the mound back to the village, and shaping it into a stove. Although this type of binde used less firewood, it often cracked and disintegrated with repeated use.

To overcome these challenges, the Proyecto Tití team set out to improve the design and create a more durable, efficient cookstove. Through this effort, we developed a method for making bindes from clay and sand—materials readily available in most rural communities.

Why Bindes Matter

Our studies have shown the significant benefits of using a binde:

  • A family of five typically uses 15 logs per day when cooking over an open fire.
  • With a binde, that same family uses only about 5 logs per day—a reduction of nearly 70%.
  • Bindes can burn a variety of materials beyond firewood, including corn husks, yucca tassels, and other agricultural residues.

This reduction in wood consumption helps conserve trees and reduces pressure on Colombia’s remaining forests.

Today, most rural communities in Colombia have access to electricity, and only a small number of farmers in remote areas continue to rely on open fires. While our bindes program is no longer active, we continue to share these instructions in case they are needed by individuals in isolated areas. This knowledge remains an important part of our Legacy Community Development Programs.

How to Make a Binde

Primary Materials

  • Clay (smooth, moist, and free of rocks, sticks, or roots)
  • Sand (fine, clean, and free of debris)
  • Water

Step-by-Step Instructions

1. Collect Clay

The color does not matter. What’s important is that the clay is smooth, moist, and malleable. Clay gathered near rivers is often cleaner.

2. Collect Sand

This will be mixed with the clay to make the material easier to work with.

3. Remove Debris from Clay

Eliminate sticks, stones, and roots to prevent cracking during firing.

4. Sift the Sand

Use a sifter to ensure the sand is free of stones and debris.

5. Mix Clay and Sand

Combine equal parts clay and sand. Mix thoroughly until the sand is no longer visible.

6. Add Water and Knead

Form a mound on a flat surface. Create an indentation in the center and pour in water so it doesn’t run off. Knead the mixture like bread dough, removing all air pockets. The mixture should be moist but firm enough to form coils.

7. Begin Forming Coils

If the clay is too sticky, add a little sand.
Tip: If your finger sticks when gently tapping the clay, more sand is needed

8. Shape the Coils

Continue rolling several coils until smooth. Coils should be approximately 5 cm wide and 30 cm long.

9. Prepare the Base

Use a heavy piece of plastic as your working surface so the binde can be removed easily. Shape the coils into circles, overlapping the edges and smoothing attachment points. Remove all air pockets.

9. Prepare the Base (continued)

Once the base is formed, begin adding coils to build upward in a conical shape.

10. Form an Inverted Cone

When the height reaches about 10 cm, begin setting the coils at a wider angle to form an inverted cone.

11. Smooth the Surface

Use a damp sponge or cloth to smooth and shape the binde, supporting the clay from the opposite side. Ensure all air pockets are removed.

12. Create Pot Supports

Attach three small clay pieces to the inner opening at the top—these will support the cooking pot while allowing smoke to escape.

Alternative: Cut three rectangular openings using fishing line, wire, or strong thread.

13. Create Wood Opening

Cut an opening at the bottom of the binde for placing wood. Push the clay outward from the inside and smooth the edges.

14. Final Dimensions
  • Height: 15 cm
  • Width at base: 30 cm
  • Width at top: 25 cm

These dimensions work well for most Colombian cooking pots, but the design can be scaled.

15. Dry the Binde

Let the binde dry in the shade for one week.

If not built on plastic, slide a fine wire beneath it to separate it from the surface.

Firing the Binde

16. Pre-Heat in the Sun

Allow the binde to sit in the sun for 2–3 hours to acclimate before firing.

17. Remove Carefully from the Kiln

Use tongs or sticks to lift the binde out and place it aside to cool.

18. Test for Proper Firing

Gently knock on the sides—like knocking on a door.

  • A properly fired binde sounds light and porcelain-like.
  • A heavy sound means it is under-fired and may crack during use.

19. Your Binde Is Ready!

To prolong its life:

  • Keep it away from water (avoid spilling hot water onto it).
  • Do not extinguish the fire with water. Instead, let it burn out naturally or remove the wood to extinguish separately.
