With the traditional mubakhar, it is hard to control the heat of the charcoal unless one uses ashes beneath and on top of the charcoal, but this can be laborious and is still too hot to give the chips longevity. With a good electric burner that gets hot enough to emit smoke from the chips but not hot enough to burn the chip completely, one will be able to enjoy the smoke for a lot longer up to 30-45 minutes easily. I have seen this happen on more than one occasion. unfortunately, i don't own a good electric burner that gets hot enough to emit smoke, instead i burn frankincense on the one i have because it gets hot enough to melt the resin and fill the air with a nice citrus aroma! I am still looking for an electric burner that will get to the right temperature.
