Handcraft finishing created by De Castelli for indoor and outdoor use. It consists in coloring copper, involving several phases: burnishing, manual brushing to get the ”scratched” effect and application of a protective, transparent varnish. The application of this finishing is not advisable on surfaces subject to daily wear and tear (ex: table tops and/or floors). Differences compared to the sample provided are not to be considered as a manufacturing defect, but as a feature of the manual processing, that may be susceptible to variances in color and homogeneity. If placed outside, the finishing can experience dissimilar color alteration, which should not be considered faults. For cleaning and maintenance only use a cotton cloth dampened with water or specific neutral products for varnished surfaces. Do not use abrasive cloths, solvents, alcohol or strong detergents. Dry the surface thoroughly in case of standing water.
