One of my bonsai pots, that was bisque fired, had a crack at the foot edge
and a small chip came off upon closer examination. It is a nice small pot and
one of the first; I wish to save it.
I mixed some Elmer's white glue with the original clay in slip form and
reattached it. I am hoping that when it is glaze fired it will fuse together
(during vitrification). The glue is for attaching before firing and will burn
off in the kiln. Is this a reasonable procedure, or did I just make up total
nonsense ;-) ? (being a Newbie this is not inconceivable ;-)
Grinding it with a Dremel is not an option due the chip's location and form.
Any thoughts on this or any other procedure that has been tried andt tested?

Luis,
Glueing the chip on and then glaze firing will work, provided the chip is
secure in its position. If gravity would cause it to fall off without the
glue, then it will fall or slip during the glaze firing. Also, despite
replacing the chip, you will probably have a crack at the chip's location.
You may be better off to simply apply glaze over the chipped area. It will
be imperfect, but not as noticeable as a chip-shaped crack, or, worse, a
chip which has slid out of its intended location.

Hi Luis,
I have one small suggestion. When you use the slip from the
original clay, instead of water, use Miracle Water. The recipe is in the
archives. It is Lana Wilson's recipe. Then, if you have any bisque of the
original clay, grind a little bit to powder with a mortar and pestle and
add that to the slip. I have found this makes a much better join. I got
this information either from Clayart or from a book, sorry, I can't
remember who should be credited for the idea.
Good luck, and if you cannot find the recipe for Miracle Water, let
me know and I will hunt for it and send it to you.

Thank you all for the helpful suggestions!
I have tracked down the miraculous 'Miracle Water' in the archives ;-) For a
moment I thought I might have to make a pilgrimage to some distant exotic
land for this 'Miracle Water' ;-)
I've also noted that vinegar alone and mixed with slip is good for attaching
elements, not to mention 'Spooge'! ;-)

Attaching stoneware use vinegar, and according to John Gill, for porcelain
use Karo syrup.
Also Aardvark Ceramic supply in Santa Ana, Ca has stuff they call TENAX,
which you can use on greenware or bisque ware to attach. I'm pretty sure it
contains sodium silicate. It just leaves a grey line that glazes will not
adhere. Otherwise it works well.
