this is the best way for making copper oxide Get some copper and grind it up as small as possible. Once the filings are small enough, place them on a flat backing tray type thing (I found something which is use for cakes, it only needs to be flat and the size of a frying pan) Then go to the kitchen and find the biggest element on the stove, turn it up to full and place you pan thingy with the filings on it. After a few minutes you will start to see the filings change color, every now and then you will want to give the filings a toss and shake. You will want to keep the filings on the heat until they stop changing color. I did this with copper filings (the copper filings were half oxidized in the oven, which took hours. When I put them on the element it was done in about 10minutes! It may take a bit longer as my filings were half oxidized, but they were larger filings so this could take about the same time)
