Embodiments of the present invention are directed toward systems, methods and devices for improving information access to and device control in a home automation environment. Further, the invention provides a method for increasing efficiency of a fermentation reaction. Removal of lead from the bulk of the lead-containing glass, as opposed to the surface and areas closely adjacent to the surface of the lead-containing glass, can allow for the production of recycled glass that includes substantially no lead within its boundaries. Steps on the conductor plug can be reduced.
