Next we mixed up a dry blend of herbs with some Gum Tragacanth which we dissolved in warm water. Gum Tragacanth acts like the "glue" to then form incense cones. The other important ingredient is a cautious amount of salt petre which is what helps the cone incense burn slowly and consistently. Too much and it burns too quickly. Too much and it goes boom! The above bowl was 3 T. allspice, 3 T. powdered roses, 3 T. dragons blood resin and 1 scant T. salt petre. Essentiallly, the salt petre is about 10% of the recipe by volume.
These dry mixes were slowly blended with the Gum Tragacanth water and then everyone got their hands dirty and made incense cones.
