[Jewelry making - Article 00012] - [Orchid] A different Argentium problem

Hello everyone -

    I am writing with a slightly different argentium problem. I have
    been using 24ga argentium sheet (from Stuller) to make hydraulically
    formed cuff bracelets with a rolled line fold in the middle. 

    I anneal after hammering the line fold but before opening the fold. 
    Next, I roll the fold, then I solder the rolled line fold shut with
    Rio's medium sheet solder (Melting pt - 1275F, flow point 1360F). 
    Finally I do the forming. 

    Initially, I was having problems during annealing.  I was very
    careful not to over heat the metal but I did quench it hot, at which
    point sections broke off and cracks developed. Assuming my technique
    was at fault, I let the metal cool and successfully annealed. 

    Recently, I am finding that touching the piece during the soldering
    operation, has caused sections to break off. Basically, I attenpted
    to move the bracelet into a better position while heating. I used dry
    room temperature forceps. Bad move - I broke off a whole flat section
    about 1cm square. 

    So, is Rio medium solder too "hot" for what I am attempting? Should I
    hold out for the dedicated Argentium solders now available? Finally,
    is it bad to quench my regular sterling hot? 

Inquiring minds want to know -
Debby
