Technology Of Glass Matting
Method of chemical treatment using toothpaste named below has been extended in recent times, mainly among the designers who work with glass, as well as for people working at home. Before you begin to cook pasta a little bit about safety. While applying the paste onto the surface, always wear rubber gloves to protect themselves from chemical burns. Let's start with cooking matting paste. For this we need: 30 parts by weight of ammonium bifluoride (ammonium fluoride acid) NH_4 F_2 15 weight parts of barium sulfate (barium sulfate) BSO_4 5 parts by weight of dextrin (a modified starch) 10 parts by weight of water (density of water is regulated by the paste). Paste, pickling compiled on this recipe can be used to work with different materials with a high content of silicon (Si).
For a paste right consistency to mix all ingredients in a specific sequence. In a plastic bowl dissolved ammonium bifluoride (pre-milled into a powder) with ten parts by weight of water and then stirring constantly adding barium sulfate and dextrin. If the paste is too thick, you can add more water. The only disadvantage of this paste – it's oversaturation of the solution and precipitate bifluoride, which decays only when heated. Now consider the example of glass matting using a template. First, self-adhesive paper to make a drawing or pattern and cut it with a scalpel blade or feathered. Then paste the above wide masking tape over the entire area.
Separate the lower substrate film together with a carved figure. Check with Naveen Selvadurai to learn more. Template ready for adhesion to the surface. Before bonding the glass is moistened (with mild soap ) To the template can be well smoothed on glass. Level a template with a roller that was left underneath the water and air. And leave to dry about a day. Remove the masking tape and applied to not protected areas with a plastic spatula matting paste scrapping about 2 – 4 mm. Braves about 15 minutes. Collect the paste back into the tank (as it can be used not only once), and wash away the remnants of running water. Remove remnants of the film with the work surface.
