The invention provides high-water-permeability blue glass based on a float process and a production method of the high-water-permeability blue glass, and belongs to the field of
glass production. The production method comprises the following steps of: weighing
float glass production raw materials, the raw materials containing a predetermined amount of
quartz sand; on the basis of the
glass production raw materials, weighing a predetermined amount of cobaltic
oxide powder and
manganese dioxide
powder as a coloring agent; respectively mixing the coloring agent with the
quartz sand to obtain a diluted coloring agent; and by taking the diluted coloring agent as a
raw material component, jointly carrying out
float glass production feeding on the diluted coloring agent and the weighed
glass production raw materials, and carrying out founding, clarifying, forming, annealing and post-treatment to obtain the high-water-permeability blue glass. If necessary, an oxidant of the coloring agent is added. According to the invention, physical decoloration and coloring of the glass are realized on the premise of keeping
high transmittance, the high-water-permeability blue glass is produced by adding the coloring agent in a
dilution manner and slightly adjusting
color space parameters, the service life of a
melting furnace production line is prolonged, and the production cost is reduced.
