Abstract
A method of making a mask support structure for a cathode ray tube includes the steps of slowly rotating a quantity of sdolder glass paste in a container continuously over an extended period of time so that its viscosity is significantly below an original value, permitting the rotated solder glass paste to stand substantially still until it returns near its original viscosity value, dispensing the solder glass paste in a metallic mask support rail having a generally hollow cross-section, and securing the rail to a CRT faceplate.
