Abstract

This invention relates to a smoke-producing composition containing a dye 1,4,- benzenedicarboxylic acid. The acid is useful for purging slag and solid clinker while lowering the steady state burning temperature of the composition. The coloring agent used by the composition does not degrade. The acid is an efficient coolant for the composition and takes advantage of sublimation reactions to produce the properties enumerated here.
