Resin incense has been used since Biblical days - pure and natural gums & resins straight from the plant and presented in solid, dried pellet form to be heated as incense. The term 'resin incense' also often refers to botanicals, herbs and plant matter like leaves, barks, flowers and wood pieces, which are burned in a similar way; the phrase 'charcoal incense' is also occasionally used as most types are usually burned over a charcoal bead or tablet.
The typical way to burn your resins is over a charcoal tablet, which is much like a bbq heat bead: once lit it stays alight for a period and provides the heat to warm your resins and allow them to give off their aromatic smoke. Resins can also be warmed using purpose made incense warmers, or even over coals or embers by a fire - but if you're new to resins, the simplest method is with self-igniting charcoal tablets, which are inexpensive and easy to use
