Delias,

    You didn't mention if your are using any fire scale flux on your
    projects. From you post I assume you are not using an anti fire
    scale flux. If you are you would not be getting fire scale on your
    smaller project. If you use the the same size torch tip on heavier
    projects you will have to heat the metal longer. The amount of fire
    scale that forms on sterling will depend on how long you heat the
    metal. The longer heating period the heavier fire scale. 

    If you are using an anti fire scale flux and are still getting fire
    scale you may be heating the metal for too long a period of time
    which will cause the flux to break down. The anti fire scale flux
    will work for a period of time than it will start to break down and
    fire scale will start to form. The longer you heat sterling with out
    the protection of an anti fire scale flux the heavier the fire scale
    will be. 

    Prips flux will not work better than any of the commercial products. 

    Use a commercial anti fire scale flux,a bigger torch tip and heat
    for a shorter period of time. To prevent heating too long you may
    have to solder in steps. Be sure to coat all the metal, front and
    back, with the anti fire scale flux. 

    I do manufacture Cupronil. This post is not intended to be an
    advertisement for any commercial flux. What ever you do use some anti
    fire scale protection. With proper fluxing and heating we should be
    able to eliminate that $#%^ AT #)_*&% AT !^& cursed fire scale.
