According to the glaze material for the Jun red glaze and the process for preparing the Jun porcelain by utilizing the glaze material, spodumene and zirconium silicate are added in the glaze material for the Jun red glaze, so that the fired Jun red glaze Jun porcelain is bright in color, mild and smooth in glaze surface, and uniform in cracking, and breaks through the condition that the general Jun red glaze Jun porcelain is dim in color and nonuniform in cracking; the Jun porcelain is taken as the specialty of China, and represents the advanced level of the manufacture process of China, and the social value of the Jun porcelain is improved.

A process is provided of providing glyoxylated polymer additives to a paper making process which brings about improvements in drainage properties of a cellulosic pulp material along with the ability to increase the dry strength of a resulting paper product. The process uses concentrated glyoxal to generate a working solution of a glyoxylated polymer additive which can be generated on site in a paper mill and used within a 24 to 48 hour interval. The ability to glyoxylate polymers in a working solution concentration provides for a more active additive and which can be supplied in a more economical fashion than conventional glyoxylated polymers.
