    The following has just gone out with the JPM email newsheet 

    .. and I'd love to hear of any personal experiences using laser
    welding on antique pieces. 

    LASER WELD REPAIRS TO ANTIQUE JEWELLERY. 

    Laser welding is now commonplace in jewellery manufacturing and
    repair. The technique, which affects only microscopic areas and uses
    very localised heat, is increasingly being used to make almost
    imperceptible repairs on antique gold jewellery. Those involved with
    antique jewellery in any capacity should recognise the characteristic
    weld marks (for examples on a Victorian locket hinge see
    http://www.jpm-international.com/JPMGallery/Laserweldjpg.html ). A
    use of laser welding in the restoration of a seventeenth century
    enamelled gold and silver monstrance has recently been published (C.
    Innocenti, G. Pieri, M. Yanagishita, R. Pini, S. Siano and A. Zanini.
    Application of laser welding to the restoration of the ostensory of
    the martyr St. Ignatius from Palermo. Journal of Cultural Heritage,
    4, no. Supplement 1 (2003) 362-366 - first reported at a conference
    on Lasers in the Conservation of Artworks (LACONA) held in Paris in
    2001). The authors believe that this is first application of laser
    welding in the conservation of a work of art. The 'non-reversibility'
    of the joining process will attract some criticism from within the
    conservation community. 

    By the way if any of you would like a copy of the whole newssheet by
    email (topics range from recently excavated ancient jewellery to  De
    Beers talk's with the US Justice Department) just send an email to
    info AT jpm-international.com and put 'sample' in the subject line. 
    The newsheet goes out two or three times a month and it's free to
    sign up.
