Using your torch and reducing flame headset at medium heat, begin heating up both of the metal pieces at their joint point until they reach about 600 degrees Fahrenheit (be sure not to exceed 900 degrees F). At this temperature range, it should take about 4 minutes for everything to get nice and hot—which is ideal for silver soldering mild steel!

afaik any silver solder will work for brass and copper. Sil fos doesn't need a flux for copper but does for copper alloys. Easyflo is a common and works well. I does contain cadmium though, so should never be used for anything food related and really you don't want to breathing the fumes all day long.

Place your silver sheet to one side and apply a small amount of flux to the top side of your copper sheet. Make sure the area that is covered is roughly the same as the size of your silver sheet. Once the flux is applied you can place the silver sheet on top of the copper sheet, ensuring that the solder is face down on the copper sheet.
