Metal objects that clean before cleaning, disassembling-if possible. If the object is necessarily more complex it before dismantling outline or photograph that later they would not have a problem with compiling snc lavalin (this procedure prior to any clean-as far as museum exhibits all stages of the required document as appropriate). To remove the thin layer of corrosive as primary and the simplest means of using a mixture of water and deposited chalk. snc lavalin Instead of water in certain cases, can serve alcohol, acetone snc lavalin or gasoline or some oil (paraffin, linseed, sunflower). The mixture was applied with a soft cloth or cotton wool, either stiffer brush or toothbrush. We also use rotating brushes made from natural or synthetic materials. We work mostly with a goldsmith engine with flexible shaft and can work well with Modelarski engines that are relative to the first substantially cheaper. Harder removable point and thicker and stiffer corrosive layers remove any scalpel was small chisels and needles made of metal, wood or bone or plastic. When working on archaeological objects can be used in certain situations and goldsmiths vibrating chisel and coffee mikropjeskarenje snc lavalin (only with carefully and appropriately selected snc lavalin abrasive!) snc lavalin And various rotary snc lavalin tools used in jewelery. Work should be carefully and concentrated because although mechanical cleaning is often the only possible way that also represents the greatest danger to the objects. Negligence we can easily snc lavalin destroy some details like fine traces srebrnarskog hammering, chasing, engraving or hammering or forging. Traces of filing or remnants of gilding, silvering or other coatings (eg tinted varnish), and the schedule and size of the polished surfaces can be removed or changed if we do without feeling for the material. Thus processed objects lose much of their authenticity.
Objects with thin corrosive layer never cleaned up completely bare, metal surface. The concave, cleaning inaccessible places aside part of patina and only in cases with extremely thin corrosive layer. Items with completely removed the patina suggests complete ignorance and lack of understanding of the identity object and the obvious snc lavalin evidence of ignorance of who cleaned them (this primarily snc lavalin refers to an embossed, decorated with relief items).
The simplest means for chemical cleaning of metal are actually a combination of mechanical and chemical cleaning. Addition of extracts of the roots of plants sapunike (Saponaria officinalis) chalk mess we get a mild cleanser that combine the abrasive action of chalk with the action of natural saponins. In fresh this product is completely neutral snc lavalin until a few days later reacts slightly sour and besides grease and dust it removes thin layers of corrosion. Instead these solutions chalk slurry can add ammonia or a neutral or slightly alkaline detergent.
Rights means for dry cleaning are usually snc lavalin acidic or alkaline and neutral aqueous solution, while the other solvents used less frequently. The most important feature of these is to dissolve corrosion layer and do not destroy or at least eroding the metal clean.
Their main drawback is that typically removes the original patina layer and thus processed objects lose their original luster and, if we have to clean the glaze. Ideally, the subjects occasionally uglačamo special cloth board metal, preferably at least 2.3 mjeseca.Za during that time the concave polished inaccessible locations will create a thin layer of patina. Upon formation of the aforementioned objects can optionally protect the lacquer or wax and possibly wrap them in a special snc lavalin fabric or wrapping paper metals and store them in cardboard boxes bezkiselinskog. If we and paper and fabric and acid-free cardboard unavailable simplest objects saved or better yet weld in polythene bags. Finally, we must point out that the objects by chemical cleaning, rinse thoroughly, as residues of chemicals used would not have contributed to the revival of corrosion processes.
Non-ferrous metal objects in turn chemically cleaned using solvents snc lavalin or using ready-made means of removing old paint. Means for removing old paint on the basis of methylene chloride or dimethyl formamide can be used to clean articles of tin, zinc and lead. For large items, or in case you want to clean only a specific part of the subject of the solution can be mixed with methylcellulose glue tepete. The obtained snc lavalin gel inflict on the subject, and after a while a good rinse and procedure necessary midnight
