I have a Tenmoku glazed stoneware jug (pitcher) that the handle was damaged.
The breaks are fairly clean and the handle is in three pieces. I'm looking
for suggestions on the best way to repair something like this.
- What epoxy is best?
- What is the best way to match the glaze and fill the seams where the breaks
occured.
Any input would be appreciated.
Thank you,
Stephen

Stephen Sell,
I resently did some repair work on the spartan sculpture for Michigan
State. I used a combination of West system boat epoxy and color kits
from East valley epoxy for my room temperature glaze and East valley
epoxy putty and calcined clays to fill cracks the stuff is amazing!
Good luck
Curt

Dear Stephen,
clear epoxy resin is best, it used to be made by a Swedish firm "Plastic
Padding" but has now been taken over by an American Company, so you should
be able to get it easily. The best way to use it is to mix in a little
powder paint of the same colour. Try a little first as it can dry a little
bit different than your mix prior to setting (approximately 10 minutes). You
need to mix only a very small amount and add about 50% powder paint (any one
will do, the cheaper the better) to the epoxy mix so it is relavively stiff,
then force it into the crack or opening and lay on its side, as it settles
press it in again (a knife blade), it dries shiny, so could match the glaze,
or if the glaze is a little dull burnish the set epoxy with caborundum stone
or paper. Anyway suck it and see. It works for me when I have to stick my
chimney pots together, or repair glazed tiles for a London Pub.

Hi Stephen.
I took a china mending course and learned that the best materials are :
1. For glueing, Devcon 2-ton epoxy (30-minute cure; not the 5-minute kind)
2. For filling chips and seams, the same Devcon epoxy with 50/50 mixture
of zinc oxide and titanium oxide added to it. The oxides stiffen it,
prevent shrinkage, and add whiteness, which is good because white is the
easiest base from which to match colors.
3. For painting, clear acrylic with dry pigments added to it, thinned with
xylene. (There are probably simpler ways with fewer ingredients but I dont'
know them)
4. For a top coat, you can just use the clear acrylic, or, if you want to
invest some $$ to make it REALLY durable, Napa Urethane Clear Coat, a
two-part catalytic auto body finish that costs abotu $40 for a pint
(including the little bottle of hardener.)
I dab the epoxy onto the broken surfaces with a toothpick, putting it only
in the middle so that when I press the broken surfaces together, it spreads
to the edges without oozing out. If it does ooze out, you can clean it up
with an exacto blade after it dries. For filling, I dab the compound into
the gap and then smooth it with a finger dipped in water. If it's not
perfect when it dries, you can sand it before painting. As far as how to
"match the glaze," I really suck at color matching and can't help you with
that. :)
Sincerely,
Sue Christensen, in Minneapolis where it felt like winter this morning but
will be summer by late afternoon
