glue to repair clay wine cooler (wine brique)

Hello --

I have a porous clay pot which is used to keep a bottle of wine cool, once
the pot is soaked in water for a while. It looks like the same material as
the Romertopf clay pot cooker.

Sounds like terra cotta.

It needs gluing back together.

Can readers recommend the correct glue for this purpose?

That's a tough one. I've seen Liquid Nails recommended for gluing terra
cotta pots to each other for craft projects; I don't know how well it
would stand up to the water, though.

I just did a quick google for "glue terra cotta" and came up with
several possibilities, including this discussion:

Good luck! If you find something that works, report back to us, OK?

Look for "Gorilla Glue." I think it would probably work. A testimonial
on their site claims to have had success repairing clay pots:

My mother's house was held together with Gorilla Glue. :-)

My first thought is epoxy glue. I presume
you thought of that and rejected it
for some reason? Epoxy comes in a number
of formulations for varied uses and is
usually my first choice for 'difficult' repairs.

Thanks to all.

I will look into epoxy and gorilla glue.

Color matching is not too important.

Here is a web site with more than you could
possibly want to know about restoration and
conservation of "ceramic" objects:

http://www.antiqueresources.com/arti...icrestore.html

The information pertinent to the current
thread is excerpted he

Adhesives, particularly for use on porcelain,
have always been a problem due to their yellowing
and viscosity. There have been considerable advances
in the use of EPOXY RESINS for BONDING and more
importantly for matching "color fills". When properly
manipulated and applied these materials give the
restorer the ability to mimic depth, translucence
and color when filling voids, glaze loss, rivet holes
and chips specific to the areas of damage without
obscuring original surfaces. It can also be used to
imitate parian, jade and cloisonné. We are hopeful
that under the right conditions of after care we will
see these applications lasting decades rather than years.


However, this and all the other references I've found to gluing ceramics
with epoxy (or cyanoacrylate "super" glues, also often recommended)
refer to glazed ceramics; porcelain and other highly-fired ceramics have
more in common with glass than with terra cotta, which is highly porous
.. The fact that the item in question is intended to be soaked repeatedly
in water to cool down the wine bottle would, I think, have some bearing
on the adhesion.

It might be interesting to get an old terra cotta flower pot, break it
into several pieces and see which adhesive works best ...

The reason I referred people to the conservation
and restoration site is because it has information
dealing with ALL forms of fired clay, and porcelain.
And conservators/restorers have a particular concern
for getting it right the first time and for the
longevity of the repairs they make.

As for epoxy use, I mentioned that there are several
different formulations for epoxy. Some are considered
highly water resistant, others oil resistant, etc.

My personal preferrence for 'easy to find' epoxy is
the one sold as 'cold weld' - containing fine metal
particles. I have used this formula on some very
difficult repairs that had to hold water, and even
on pressurized containers where a solid seal was
essential to keeping the container pressurized AND
full of water. I'm not certain why the metal particles
make the epoxy work better - maybe the particles act
in the same way that aggragate does in concrete.
Whatever the reason, I opt to use the 'cold weld' stuff
in preference to clear epoxy whenever appearance is
not a big concern.

I glued a large italian terra cotta flower planter together with clear
silicone bathroom sealer about two years ago. Still working. Wipe very
carefully with recommended solvent, apply silicone, tie together with
stretchable string or old pieces of inner tube and let set, then
carefully shave off any hardened sealer that squeezed out of the crack.
If you try and wipe it will discolor the clay. There might be some
colored sealer available to match your clay color.
