Bloom On Float Glass

Bloom is an interference pattern of optical wave caused by the wrinkling surface of heat treated float glass. Bloom parameter is discussed in this paper and the following results were obtained by experiments and calculations: The bloom parameter is a good description of the light or heavy level of the glass bloom. The smaller the parameter, the heavier the bloom; The parameter is approximately proportional to the total amount of tin in the glass; It decreases by exponential law as the treatment temperature increases; No definite relation exists between it and the tin concentration on the glass surface.
