  • Arghhhh Casting grain nightmare!!!!

    Hi all,

    I recently brought some casting grains with a view to cuttlefish casting- this has turned into a bit of a nightmare. First of all I seem to be able to melt only a small amount of silver and then it wont pour out!!! It is glowing orange and spinning like mad before I try. I'm not sure if its my torch (a cooksons one) or the scorifier (only a small one which is made out of similar material to a soldering block) I am using. Does anyone have experience of using casting grains? Can you please advise and get me out of this casting grain nightmare!!

    I haven't done it myself but I think you have to add flux to the metal to make it flow. I'm sure someone who knows better will say if that's not so.
    Best wishes

            I'm not sure whether the cooksons torch has a big/hot enough flame.
            I have one of those torches myself and it is quite small.

            As well as adding flux, make sure you keep the flame on the molten silver as you pour to keep it flowing

                I know when I was doing my silver smithing course we tried it and we had two torches working on the silver. Maybe you need to stand it on another heat source like a gas ring?

                I am sure one of the jewellers here will be able to help
                Take care
