This work seeks to contribute to the technological alternatives for the reuse and recycling of glass, which can offer a number of advantages for the environment, and reducing the costs of collection and manufacture of the product, using the glassy residue of fluorescent lamp as a flux in production of white ceramic. The disposal of fluorescent lamps cause irreparable harm both humans and the environment. Therefore, it becomes of paramount importance to this study. The research characterizing porcelains formulated without waste glass and waste glass partially replacing feldspar in the proportions of 5%, 10%, 15% and 20% were then molded specimens was performed at 1000°C and burned, 1100ºC, 1150ºC, 1200°C and 1250ºC. These specimens, physical and mechanical tests were performed, such as: X-Ray Diffraction; morphological characterization and flexural of ceramic bodies. The results indicated the feasibility of using this waste in partial replacement of feldspar before his potential as a flux for this type of application since, in general all the samples showed results within the recommended specifications for the ceramic industry white.
