Abstract
The invention relates to a method of aluminizing the inside of the panel of a television picture tube. When aluminizing the inside of the panel, blisters caused by the vaporizing lacquer, are likely to develop in the layer of aluminum, especially on the side walls of the panel portion. When taking care in accordance with the invention, that the coat of lacquer is roughened prior to the performance of the aluminizing process, these blisters are avoided.
