Hi All

Being  half-way  through  a  massive  professional   photo-shoot  of my  entire   collection  (@ US$20 / hour   -  just  for    studio  time   -  of  more   which later )  I have  faced  the  inevitable  problem  of  broken  stoppers ,  of  which  domestic    Chinese   glues    dry  out  with  age

I have  come to the   following  conclusions,  unless   someone can  enlighten me  to  the  better :

a)  a  loose   stopper   is  by  far better  than  a  tight    stopper

b)    a  little  bit  of  vaseline    can  convert  a  tight    stopper  into a  freely-opened   stopper
   


THAT's a  highly  controversial  point  !  But  Vaseline,  having  a  low  vapor  pressure  and  - I assume -  being  compatible   with  oil-based  paints  -  should  have  minimal  effect  on  the   painting  inside  ??!!

c)  Super-glue ( e.g.  Aron-Alpha )   is   the  best remedy  for   broken  stoppers  ....  but  DO  leave  time  for  the   Super -glue  to    dry

Any better   suggestions    welcome !

Cheers
Peter

Dear Peter,
I suggest you to strictly avoid oily/grease substances. I donít know what kind of paint they use for IP bottles, but either watercolor or acrylic will be irreversibly affected by the oil. If by oil-based paints do you mean the same type that used for oil paintings on canvas (I would be very surprised if they use such paints on IP bottles) then too the contact with a further oil is dangerous. The oils of oil paints do dry in a frame time of a bit more than 100 years, after that they are resistant to thinners. A further oil will result in spots of enhanced colors.
I agree with you that a bit loose is better than a bit too tight. I do not care so much about glues that detach in time. Simply matter of gluing back the parts again, in my opinion that is not a problem.

Hi Peter,

I agree with Giovanni that vaseline is potentially damaging to the painting medium. Depending on what type of glue is used to hold the cork onto the stopper it may also react with the compounds in the glue itself. Apart from that, cork expands with moisture. While the amount of moisture the cork is able to absorb from the vaseline may be minimal, it's possible that any advantage of slipperiness is countered by a slight expansion.

Never tried it, so these are just thoughts...
