In my review of Ortur Laser Master (15W) I tried to engrave some metal, but without success. Then two comments suggested to me to use mustard on the surface. First, I thought it is a joke, but then I found an interesting article, where somebody successfully used mustard and vinegar for stainless steel engraving (or better word is etching). I am also trying again the marker provided with the laser, since this is recommended in the manual.
