brand charcoal is imported from Holland. It is self-lighting, which means the charcoal will fully ignite if brought into contact with a small flame, such as the flame of a candle. Each briquette is silver-dollar size and made to fit most church censers. For home use, these may be broken into smaller sizes. This charcoal is very dependable and will not emit any offensive odor to conflict with the fragrance of incense.
