    The composition of standard IT solder is by weight:- fine silver
    80%, copper 16%, zinc 4%. 

    If the square bead seam is a close fit and any surplus solder around
    the seam has been abraded back to a fine silver surface there should
    not be enough solder exposed in the narrow seam to cause enamelling
    difficulties. A method of avoiding the problem if it persisted is to
    form fine silver foil to cover the seam area, stick it to the bead
    surface, covering the seam, with a solution of gum Arabic or klyre
    fire, ensure that the glued surface is completely dry before placing
    the enamel or there is a possibility that the foil will lift as the
    enamel fires. 

Kind regards
Don Iorns
