Abstract
Systems and methods are described for forming wax shells for use with electric lighting devices. A template can comprise a sleeve that defines an interior space with a removable core at least partially disposed within the interior space. A modular top can be coupled to the sleeve, depending on the desired upper surface of the wax shell.
