It is made from a beautiful teal glass with the metal wax warmer compartment on the top and the light is inserted in the bottom. The original light finally broke to I tried to replace it. I purchase at least four different bulbs and not one of the did the job. If the fit inside the voltage was too low to melt the wax. If the voltage was higher, the didn't fit inside the teal glass . This warner needs a 25 vt bulb the size of a christmas tree light.
