PURPOSE:To enable economical treatment in a large quantity by bringing a plate-shaped body of soda lime glass into contact reaction in the presence of a reactive gaseous body of sulfur or the compd. or chloride thereof and extracting away the sodium component on the glass surface. CONSTITUTION:A plate body P of soda lime glass for an electrode plate worked to a suitable size and thickness is fed into a treating furnace 10 in which the atmosphere of a reactive gaseous material of sulfur or the compd. or chloride thereof is formed. As the plate body is successively moved by a transfer conveyor 18 to the 3rd zone, 4th zone..., the reactive extraction of the sodium component on the glass surface is successively performed. Sulfur alone, gaseous sulfurous acid or liquefied gas of gaseous sulfurous anhydride, or ammonium sulfate, ammonium chloride, etc. are generally used as the reactive chemical.
