It happens to the best: One wrong move and grandmom's valuable china is not so valuable anymore.
Sifting through tons of instructables I found many useful methods and adopted them to this special case:
- Using bees wax to hold the fragments in place
- Using two-component adhesive to glue the parts together
- Mixing baking powder with adhesive to fill missing spots
- Using a heat gun to remove the wax.
- Bees wax (or any other wax)
- Heat gun
- Two-component adhesive (or any other glue, that's strong enough)
- Baking powder
Step 1: Glue and Hold the Pieces Together
- Make sure, all pieces are clean.
- Take a piece of wax, warm it up a little bit (by hand or with the heat gun) to make it shapeable
- Apply the glue with a tooth pick in a thin film
- Mount the first broken piece. Make sure, the broke edges fit together as good a possible.
- Press the bees wax onto the mounted piece so it stays in place while the adhesive is hardening. If necessary add additional wax to form a stable structure
Step 2: Continue With the Second Piece
- Again form a soft wax ball. Stick it on the second broken piece.
- Add adhesive on the edge. It is easier to handle, if you add the adhesive on the piece in your hand than on the teapot
- Press the piece in place until it perfectly fits and stays where it should stay.
Step 3: Tip for Small Pieces
Especially the last pieces need to be placed very precisely. Use the wax to handle small broken pieces helps a lot!
Step 4: Filling Up Holes
To fill in for missing pieces simple add baking soda to the adhesive
- Add small amounts of baking soda to the adhesive while stirring it until it becomes a thick paste
- Add paste to the hole in the china until it is closed.
- After a few seconds you should be able to form and smooth the surface with your fingers. If it is still too sticky, sprinkle a little bit of baking powder on it.
Step 5: Remove the Wax
Give the adhesive enough time to harden (mine took six hours).
Then use the head gun to melt the wax and remove it from the pottery
Prepare a mould with a wick to cast a candle from the melted wax.
Step 6: Enjoy Your Tea
Thanks a lot "lakesidepottery" for the idea with the stabilizing clay structure (I used wax instead): https://www.instructables.com/id/How-to-repair-brok...
