Dear Alex

    Heat the inner of the crucibles with a torchwhile holding it so that
    the flux glass can run out, help it out with a piece of steel rod or
    the like. I also learned from an old master goldsmith that putting
    half a teaspoon of common table salt makes the melted flux glass
    easier flowing, at least this little trick has helped me. 

Kind regards
