    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

    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

    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...

    Omega clip broke in half

    Hi, I soldered an omega clip to a pair of earrings, I dropped the earring, and as you can see from the photos, the clip broke in half (not from the solder I joint). I did heat treat it- 600 degrees C for 30 min and then quench in water, followed 300 degrees for 1 hour and air cool. Both the clip...

    Surface cracks in sheet metal

    Hi, quite often I get these little areas on my sheet metal that are kind of cracks but they dont run deep. While engraving, or in this case doming, they come apart like you see in the image. In this case you can also see the metal cracking along those horizontal lines. This metal is 18k yellow...

    18KY gold when filed becomes red

    Hi, This is made from 18KY gold, but when I used emery paper on it I saw that those sections are more red (sorry its a bit hard to capture in a photo). I think its because of something to do with the heating of the metal. Does anyone know the precise cause/ how i can prevent it? Thanks

I'm open to going abroad too. Looking to learn/ improve on things like fabrication, soldering, understanding how gold...

    Hi, Ive been trying to melt my own gold ingots and roll them out into sheets but they keep cracking. Sometimes in the middle of the surface, sometimes from the sides, sometimes both. They are 20k gold, and I’ve tried three batches- two from bits of older sheets (that were made by someone else)...

    Do wider gravers make shinier cuts?

    This may seem like a very silly question, but do wider v- point gravers make shinier cuts than narrower v- point gravers? Because i even removed the high polish face and heel of my 120 degree and the cuts it made were still shinier than my high polish 90 degree graver. Edit- I just took the...
