Answer 2

The process of making herbal incense without the use of salt peter, or even charcoal is actually quite easy. However, perfecting the art is another matter. Perhaps the easiest way is by using a binder commonly called Makko. Makko not only serves as a water soluble binder, but as a burning agent as well. Makko is a natural tree bark from an evergreen tree and contains no synthetic chemicals, charcoal, or salt peter.
To make incense, simply mix the desired ingredients, in powdered form, with makko, and add some warm water. Knead the incense-dough thoroughly and form into cones or sticks and let them dry slowly. Japanese makers have ways to control the drying time. About a week in the summer and ten days in the winter.
Sandalwood is common to almost every incense formula, and serves as a wonderful base aroma as well as a burning agent of its own right. If you were making an incense of sandalwood alone, the amount of makko required may be a little as 10%. However, resins like Frankincense are more difficult to burn and must be used in much lower percentages to burning agents such as sandalwood or makko. Otherwise, your incense won't burn properly, and may me too smoky or keep going out.
Makko really just means "Incense Powder," but when we refer to Makko we are talking about a specific incense powder called Tabu no ki. It is the bark of a tree that grows in Southeast Asia, the Machillus Thunbergii tree. Makko comes in four grades, and the the higher grades have less aroma than the lower ones. What makes this powder so special is its water soluble adhesive properties, an almost odorless characteristic that seems to be entirely lost when mixed with other ingredients, and its abilities to burn smoothly and evenly.
