[Jewelry making - Article 01277] - [Orchid] Dissolving Superglue Problem

Hi all,

    One of the large alabaster bowls I sent to Tucson broke in shipping
    and in order to show it I glued it with superglue. The bowl in
    question is back at home now and I need to gently undo those joints
    to restore it properly. 

    The technical challenge is that the bowl is big, about the size of a
    half beachball, and the superglue joints are not tight. Even if I
    were to swaddle it in aluminum foil and fill it with acetone this
    would quickly leak out. The prospect of having two gallons of acetone
    leak onto my floor is not an appealing one and Canadian winter makes
    it problematical to do this - or anything else - outdoors. 

    I understand that water will weaken a cyanoacrylate bond and hence
    have the bowl submerged. However after 24 hours nothing useful has
    yet happened. 

    Is there perhaps a non-volatile dissolving agent I can paint onto
    the joints? Or a reagent I can add to the water (maybe sodium
    hydroxide?) that will reliably attack the cyanoacrylate? Any
    experience-based recommendations will be seriously welcome. 

Cheers,
Hans Durstling
Moncton, Canada
