    Cracks in sheet metal

    Thanks for your response. The cracks dont form on the side but all over the surface of the sheet and they dont tend to get deeper but remain even as i keep rolling. Im going to try annealing less often, particularly in the beginning

    Yes im trying this now - to keep going to atleast 60% reduction in thickness without annealing. Thank you

    Cracks in sheet metal

    Not annealing at all? But what about when it work hardens? I do keep the same side first in the rolling mill. Thanks for the tips about the quenching and the small rolls. Will try it. I dont have a photo at the moment but if/ when it cracks again i will take one and share

    Cracks in sheet metal

    Hi, I have been struggling with my sheet metal cracking while rolling for a long time now, and I can’t seem to find a solution that works for me. I have tried different annealing temperatures, rolling while reducing the pressure only slightly, quenching in water and alcohol. Once I melt it, I...

    Solder melting through silver

    I tried cleaning with abrasives and pickling. Yes the gold does have a chance to melt sooner but I even tried sweating the solder onto the silver and it still forms these holes

    Solder melting through silver

    Hey, I was making a piece which involved soldering 18k red gold wires to a Sterling silver dome. Most of them worked out fine, but for a couple of them the solder would burn through the silver and disappear rather than flow on top of it. I was using 18k red easy solder but layer tried with 18k...

    Gold turning greenish in pickle

    Thanks for your post ralf. I will try the abrasives first. Nitric acid might be even harder to get in India if its not available in Germany so will have to check on that. I do cover my piece with boric acid and alcohol but I think leaving it in the pickle results in cleaning that up plus...

    Gold turning greenish in pickle

    Hi, I made a piece in 18KY gold and the piece has got a greenish colour to it. I think it is caused by leaving it in the pickle (I use a citric acid pickle). From my understanding, it is caused by the copper leaching out of the surface of the metal into the solution. If I polish the surface...
