Summary for metal embossing sheets Discussion
Metal embossing sheets for art project: Christine Winrow asked how to protect embossed brass, copper, and aluminum sheets from inevitable tarnish for a children’s charity wall hanging. The thread excerpt only shows a brief answer suggesting Incralac, described as a brass lacquer plus benzotriazole, as a possible protective coating. Because the excerpt is truncated, no further discussion, application method, or long-term performance details are available. The practical takeaway is that a clear protective lacquer specifically intended for brass and copper was recommended, but the source text does not provide enough information to confirm durability for years or whether it is suitable for all three metals in the project.
Q. I am a volunteer with a children’s chronic disease organization and we are creating an art project made by the children and auctioned at the yearly gala. Our project consists of brass, copper, and aluminum sheets (36 gauge) that have been embossed by the children. We plan to create a collage of these pieces, Mount and display them in a 3-D effect for a wall hanging. My question relates to the inevitable tarnishing of the brass and copper sheets. Is there any product we could spray, paint, or dip these sheets into (each sheet is about 6 x 8 inches)that would protect them for years?
