Hi,
I have a one of a kind cup with a small hole in the side wall.
It's a kooky artsy yunomi type thing so can't really remake it, I know I should smash it but I love it.
I want to try the trick of filling with gold which I think is called Kintsukuroi.
Does anyone know how to do this?
Can i crumple up gold leaf and pack it in there?
Hoping Baymore San or one of you other masters out there might know.
I could fill with epoxy I guess but I doesn't seem right somehow.
Again, I know I should let go and smash it but I really would like to save it if possible.

Thanks!
Tim

If I'm not mistaken the technique is actually using a laquer resin sprinkled with gold, not actually filling the cracks with gold...

I cant vouch for the efficacy or authenticity of the information contained in these links, but a google search yielded these:

Tim,

Here I am......... ;)src="http://ceramicartsdaily.org/community/public/style_emoticons/default/wink.gif"> .


The technique is to glue the cracked pieces together or fill in the break with a layer of what ius called urushi (Japanese lacquer, and then do one of two things.......

One way the gold is added is to mix 24 karat gold powder with the urushi before the patching is done. This means that the gold appearance is throughout the lacquer repair. This is the more durable method,.... but the more expensive.

The second method is to let the surface of the urushi projecting on the surface of the piece to get partiallly dry and "tacky"..... and then press gold leaf onto the surface to put a thin layer of gold there. Cheaper, but easier to wear off.

It is VERY, VERY, VERY important to stress here that actual urushi is the sap from a plant/tree that is sort of related to Poison Ivy/Sumac... and gives you a HORRIBLE rash. Lacquerware apprentices in Japan suffer for years until they develop an immunity.

SO that being said.... here is the English language page for a small kit that is all you need to do this:

It is not as easy as it sounds. Things like the humidity of the air will ghreatly affect the drying of the lacquer. As always........ test, test, test.

Thank you both.
Hmmm ... looks not that fun .... maybe I'll just epoxy or maybe I'll step it up and smash the thing after all

make your own hammer, it makes the smashing that much more fun

My link I am curious. Just getting into ceramic's. I have very old ceramic fired hand-painted china done by my grandmother almost 50 years ago.
My link It looks
like oils on china but she also had gold fired on the edges. It is real gold leaf mainly on edges of plates. But my favorite plate had something heavy on it
and cracked in half. My husband glued it back but it left an ugly glue line. I am wondering if I can do the kintsukuroi on the break. But I think it may be
too late as the glue may be permanent. And I would like to try china painting. I do not have a kiln nor at my age want to invest in one. But I think
there are new classes in china painting. Where I could use their kiln.

John I think you might know but I've done a lot of research on this ... and what you say is true the worst thing is that the reactions is

TIME DELAYED BY UP TO THREE DAYS

so you can think it's fine and there is no reaction then three days later it's hive city!

I still have some repairs I need to do but I'll have on long gloves and a vapor mask.

I'm not really allergic to poinsen IVY, but this stuff is concentrated.
