Price Term: FOB Package: *5kg/pcs *******************************************************************************- Common Glass Frosting Powder ST***1 can frost Sodium-Calcium-Silicon glass such as lamp glass, flat glass, bottles, arts ***** ST***1 is based on industrial grade Hydrochloric Acid. It is a new type environment-friendly powder that allows a better recycling . Stable and easy to use the powder makes your glass appears softer and white. Frosting Operation >> Preparation of the Frosting Solution ·Mature the Frosting solution at least *4 hours before use． ·The ratio of powder ST***1 to Hydrochloric Acid 　(≥*1) is 1:0.*0 ． ·Keep the powder in a plastic container, slowly pour Hydrochloric 　 Acid in, and keep stirring the solution evenly. Finally, cover 　 the container. ·Keep maturation over *4 hours before use (The longer, the better) ·The newly-prepared solution is too thick, and its temperature 　will fall down slowly, so don"t apply it until it comes back to 　be normal in temperature and thickness. Frosting Operation >>Frosting Process ·Constantly stir the matured solution to be even completely ． ·Dip the clean glass wares into the solution for ****0 seconds ． · Take out the etched glass to drop for ****0 seconds ． ·In the beginning, the solution is fairly thick. However the 　etching time should be longer when the solution becomes less 　thick　after etching for some time ．　 ·The frosting time varies with the temperature and chemical 　compositions． ·For dirty glass, use *5 Hydrochloric Acid to wash． Frosting Operation >>Wash Process & Dry 　· Rinse and wash the frosted glass wares under the running water · Dip the glass into the ***0 diluted Hydrochloric Acid for ****0 　seconds to make brasive parparticles on the glass easy to 　remove ． ·Rinse and wash the glass again under the running water 　and dry it with air for package． Etching Operation >>Treatment of Waste Water
