Brass and bronze are copper alloys used for a number of decorative and functional objects. Depending on the type and content of other elements in the alloy and the conditions in which the object is located, the surface oxidizes, forming layers where there is no clear boundary between the desired patina and when it is already undesirable contamination. Objects are often affected by previous repair and renovation processes, especially various coatings. Sometimes the requirement is to remove all impurities down to the metal itself, while other times the customer considers a certain patina to be a desirable added value of a historical object. Using a laser, it is possible to relatively quickly and effectively remove impurities such as dust, old coatings and oxidation layers, and then, depending on the method of mechanical cleaning, the surface can be renovated according to the customer's wishes. We always take care not to disturb the original surface structure characteristic, for example, of the production method, such as casting, forging, machining, etc.www.lsrservices.cz
