![]() ![]() ![]() The amount of potash can be varied in a very wide range to produce different densities of black. 50 grams Sulphurated potash (Liver of sulphur) Young gives this patina in his book, Contemporary Patination (pp 69-70), where he recommends different application techniques than ours, and suggests ways of getting many different color variations. Reapply gently, so as not to disturb the first layer, which will be powdery. Brush or sponge the patina all over the metal's surface, leaving it puddled all over the piece. They are to be used at your own risk.Īdd the chemicals to the water and stir with a nonreactive implement. This process has not been tested on copper yet.NOTE: read all safety information and take appropriate precautions before mixing or using these formulas. We tend to let the parts sit for at least a day after beadblasting before we ship them to give the patina a chance to start uniformly. After you complete this process, you may consider storing the razor for about 24 hours to allow the first bit of patina to form without interference. Remember, resetting the patina with chemicals (and beadblasting) brings the brass back to it's virgin state and it will be susceptible to stains. Fingerprints created during the process, like mine, may take more effort to remove. In picture 12, you can see my oily fingerprints from touching the part, especially along the left edge near the top of the picture. Do not add tape unless you want to prevent cleaning in an area.Īlso, I'm not wearing gloves in the pictures to illustrate what your finger's natural oils can do. Please note, the electricians tape was added to show the contrast between the untouched areas and the cleaned areas. The labels indicate the total dip time to that point. Each dip in vinegar lasts about 1 minute. The images below are provided as an overview of the process. Isopropyl alcohol is very helpful for drying a razor because it will displace all water and is safe to use regularly (we clean with IPA during the manufacturing process).You will likely need to disassemble your razor and dry each piece individually. Rinsing your razor and shaking it off after your shave is usually not enough. One of the best ways to ensure that your razor forms a consistent patina is to ensure that your razor remains dry between uses.If a portion of the part is above the surface of the vinegar, accelerated corrosion may form at the surface of the vinegar (because you've created an electrolytic cell with atmosphere). Immersion in the vinegar needs to be complete.And long exposures, like leaving it overnight, will likely lead to undesirable and irreversible results. It is impossible to revert the process if you have go too far, other than by letting the patina form naturally. ![]()
