In the rendering process, the slumgum is separated from clean wax. Slumgum is slightly heavier than wax and sticks to the bottom of the wax cake. It is brown to black in color, and burns readily. Melted slumgum can be poured over pine cones to make fire starters.
Lumps of slumgum are very attractive to bees, especially when heated by the sun. They can be used to attract bee swarms. Slumgum is also called "bee bread" or "pain d'abeilles" or "Pastura" in Romanian. It considered to be medicinally valuable by some practitioners of apitherapy.
