clay lover Posted November 28, 2018 Report Share Posted November 28, 2018 have any of you had any success in UNgluing something from a pottery piece that is glued on with e6000? I have 4 broken ikibana bowls that I would like to get the large pin frogs out of to reuse. Link to comment Share on other sites More sharing options...
Mark C. Posted November 28, 2018 Report Share Posted November 28, 2018 Call the manufacture and ask them.Otherwise break away pot and grind clay off base with stationary grinder. Link to comment Share on other sites More sharing options...
neilestrick Posted November 28, 2018 Report Share Posted November 28, 2018 Jackhammer? Seriously, break away as much of the bowl as possible, then wedge the edge of a chisel in between the frog and clay and try to hammer it off. It may pop loose. Wear eye protection and gloves.

Fred Sweet Posted November 28, 2018 Report Share Posted November 28, 2018 Clay lover- Here is the SDS for E-6000. On the second page there is information about various solvents to break down the cured adhesive. http://eclecticproducts.com/downloads/tds/tds-e6000-craft-us-ca-eu-me-arabic-au-nz-mex.pdf Hope it helps.

Magnolia Mud Research Posted November 28, 2018 Report Share Posted November 28, 2018 Since the adhesive is rated only for temperatures less than 82 C, boil the frog until he turns loose. Link to comment Share on other sites More sharing options...
LeeU Posted November 28, 2018 Report Share Posted November 28, 2018 Once in the rubbery gel state you can complete the removal by picking it off with whatever works. @Fred--thanks for that info. Link to comment Share on other sites More sharing options...

clay lover Posted November 29, 2018 Author Report Share Posted November 29, 2018 Weeeeellll, took a box of ikibana bowls to gallery today that had been in my car over night with 19* temps. 2 of them had there pin frogs rolling loose around in the bowl. So, I guess freezing is the answer. durn. Never had that happen be fore. Link to comment Share on other sites More sharing options...

If you can sandblast the areas you connect them or design each part with mechanical retention in mind, an adhesive will work better. There is no chemical bond between glass|adhesive|glass so it functions on mechanical retention. Just a thought for future situation where you need to glue two parts together.

I rough up the metal surface with a diamond sanding pad, makes a difference in getting a better bond. Link to comment Share on other sites More sharing options...

Min Posted November 29, 2018 Report Share Posted November 29, 2018 From the link Fred posted it's supposed to be good from -40 to 180F when fully cured so if the frogs popped off in your 19 degrees it sounds like they might not have been attached well or it hadn't cured.

Babs Posted November 29, 2018 Report Share Posted November 29, 2018 Are you dropping frog into already boiling water or bringing slowly to temp. One is supposedly more humane Link to comment Share on other sites More sharing options...
lgusten Posted November 29, 2018 Report Share Posted November 29, 2018 This is what we do for a living....people glue things in the wrong place and bring it to us to make it better. We always start with soaking the item in very hot tap water, if that does not work, then bring the item in a pan of hot water to a boil and let it soak...sometimes it takes awhile. If boiling does not work, then pull out the paint stripper... Before you reglue, make sure all traces of the previous glue is gone. Link to comment Share on other sites More sharing options...

We just toss it in an ultrasonic full of acetone, but most people don't have one of those Link to comment Share on other sites More sharing options...

You'd be surprised at what things people use to self-repair their dentures. I got one in this week that was duct taped back together, which is something I actually prefer to see! But when I took the tape off there was almost a centimeter of epoxy built up from breaking and re-repairing. I had to strip it all off to get the pieces to fit back together nicely so they spent some time in the acetone. We repair dentures with a methylmethacrylate polymer that forms a permenant chemical bond that is immune to solvents. The reason epoxy and super glue don't work long term on dentures is because of two main things. First, enzymes in saliva are very good at breaking things down. Second, adhesives act as an intermediate layer between two surfaces so there is no chemical bond. Adhesives rely mainly on mechanical retention so when gluing things together try to give each surface as much to grip as you can. Link to comment Share on other sites More sharing options...
lgusten Posted November 30, 2018 Report Share Posted November 30, 2018 That's really interesting. We repair and restore ceramics, plaster and some stone. Stuff arriving taped together is good! Seeing stuff already glued makes my eyes roll! Super Glue doesn't work well for our work except for a temporary stick while the long cure epoxy does it's job. The only thing we use acetone for is making our Paraloid glue for conservation work on museum type pottery. Link to comment Share on other sites More sharing options...

I gotta chuckle. I had an implant come out, post intact, crown intact. Didn't have a dentist-mine moved to Vermont a few years ago and I never replaced him So when the tooth came out I went to the nearest one; they wanted a forced consult plus a "starts at" fee that together would be a minimum of about $300. I am a poor person! So I went to my trusty 36000 and it lasted for well over 2 months w/just a couple of re-dos, until I could find a guy who didn't push the consult, the cleaning, the panaramas, the lecture to floss daily or anything else. He looked in my mouth, poked around a little, then recemented the thing for $150. He explained why the e6000 wouldn't do the trick (which I knew) and how the dental cement worked, and was really nice about it. Now I'm his new patient. I think just for fun the next time I'll bring in my lower partial wrapped in some duct tape and see how that goes. Link to comment Share on other sites More sharing options...

Denice Posted December 5, 2018 Report Share Posted December 5, 2018 Liam I was a dental lab technician for 10 years, I never worked with dentures mostly bridge and crown work. I also made full mouth implant frames in the early seventies for a dentist that was developing a new type of denture. Denice Link to comment Share on other sites More sharing options...
