I think someone posted an answer to this a while back, but I am unable to find the post...
I work with poured ceramics, and I have a purely decorative piece which broke cleanly in two during firing. I want to complete the piece by glazing it, and I cannot remember the 'recipe' for the repair process. I think it involves slip and vinegar, but I cannot remember. Does anyone know of a formula for this sort of repair? Thanks!

I've not tried it myself, but I've read to use equal parts of vinegar, slip and karo syrup. It's supposed to mend even bone dry greenware. Dunno about that one. Good luck!
Slip and vinegar can work to repair unfired pieces. wouldn't it be simpler to pour another piece then to mess around with repairs? I don't think you can do it neatly at this stage.... Andrea
vinegar and slip will mend greenware ( the vinegar thickens the slip) but it is not suitable for mending bisque as the shrinking rate on the unfired bit will be different to the already fired bisque and will more than likely crack again .if the piece was just a hairline crack then you could use Duncans french dimensions to seal the crack and then glaze over it. You could try it but a complete crack will use a lot and they only come in one ounce bottles ,so it may be easier and cheaper to re-pour the piece.
