An ion removal arrangement includes a filter having a filter material made of synthetic or naturally occurring crystalline hydrated aluminum silicates having a framework structure, which contain alkaline or alkaline earth ions. The filter is formed as a double pipe cartridge having an inner pipe and an outer pipe. The filter material is filled in the annular space between the inner pipe and the outer pipe. The filter is installed in the cast iron gutter pipe of a gutter system.

By applying a reaction solution containing an aqueous solution of copper salts and salts of inorganic acids, to a pre-oxidized or partially already patinated copper surface, it is possible to produce a patina layer on copper objects, either directly at the construction site or also at the factory. The reaction solution is particularly well-suited for pre-oxidized or partially already patinated copper surfaces. Copper surfaces, which have not been completely green-patinated, or have been damaged, also obtain a uniform patina layer when the reaction solution is used. The reaction solution can be changed in its consistency and adapted to the conditions of use in each case by adding wetting agents or thickeners. The reaction solution can be applied using a brush, roller or spraying device, and can be stored and processed at ambient temperature.
