Conas a chruaíonn copar dearg

The "red copper" that you say is industrial pure copper or commonly known red copper. The quality is soft and easy to process. The method to increase the hardness of copper is "work hardening". In industry, it is hardened by rolling, extruding and stretching, etc. Under home conditions, the popular practice is "knock" hard. The copper hardens naturally when you make it by hand. The next thing you will have is that the processed copper will become hard and brittle, not suitable for reprocessing. B: I'll tell you all at once. You should have annealed the processed copper parts by now. The annealing process specification is roughly; The temperature is higher than the recrystallization temperature of copper, simply speaking about 500 degrees Celsius; The heating time (after reaching the recrystallization temperature, the insulation time) depends on the thickness of the workpiece, and then heat through the insulation for more than half an hour; The cooling process has no special requirements, and can even be directly put into water for rapid cooling -- rest assured, it will not be "quenched" like steel parts! Of course, if it is thin wall complex parts easy to deformation, or not into the water cooling as well... Ok, now you can be a copper cold worker!
