ABSTRACT:
The inner surface of a cathode ray tube is roughened by blasting the surface with a suspension which comprises radiation particles, the inner surface being irradiated in such a manner that it satisfies the inequalities 0.05 .mu.m<R.sub.a <0.5 .mu.m and R.sub.z <4 .mu.m and, preferably, 0.1 .mu.m<R.sub.a <0.2 .mu.m. The reflection at such a surface is comparable to the reflection at an etched surface. The method in accordance with the invention is safer and less harmful to the environment.
