Mica chips have been used for hundreds of years in the traditional Japanese incense ceremony, the Koh-do, and by incense enthusiasts around the world.
Tiny sheets of mica, a translucent silica mineral, are encased in a thin wire and are used as a heat buffer, in combination with rice ash, to reduce heat from an incense charcoal (buried just below a mound of rice ash). This allows the aroma of the fragrant wood or incense material to slowly release without becoming too hot and giving off an undesirable charred aroma.
*This item is one Mica Chip. Mica Chips measure to approximately 7/8″ x 7/8″.
To use, combine with rich ash and an incense charcoal block or use in koh-do style ceremony. See Koh-do utensil set description here for more details.
