Abstract
The present invention presents a method for recycling a cathode ray tube bulb comprising a panel and a funnel fritted together with a frit glass. The panel and the funnel are separated by dissolving at least a portion of the frit glass with a solution of an organic acid, such as an aqueous carboxylic acid solution, and a cathode ray tube bulb is obtained using at least one of the panel and the funnel.
