How to Repair China, Porcelain, and Glass
Careful fabrication and clamp are the key to mending ticklish objects . With patience and the right gum , you could animate even the most delicate china , porcelain , and glass .

Materials:
Time:5 minutes or more , depending on scathe
Because you ’ll take time to check broken pieces just together , quick - soldering mucilage should not be used for mending frail pieces . Buy clear epoxy glue , sold in two parts , rosin and hardener ; mix only as much mucilage as you require . Epoxy dries completely waterproof .
Clamping
Before mixing the gum , train a clinch to bear the object together while the epoxy glue cure . Choose an appropriate method acting , as detail below , to accomplish a inviolable circle . Do n’t use glue to the broken pieces until the clinch is prepared .
To hold a glued cup handle or the stem of a glass , gently wrap flight strip of masking mag tape around the cup or glass . Use at least two perpendicular strips to encircle a drinking glass with a mended stem ; keep the pressure on the strips even so the fix articulation does n’t drop away .
To keep a cracked or pieced shell or similar object , fill a pan with sand . Embed the uncracked fate of the plate in the sand , with the crushed edge flat up so that the glued spell will be held in place by gravity . If necessary , use clothespins to clamp heavy pieces in place . For a mended teapot , cupful , or mound , nestle it into the sand as necessary to hold the glued slice in place .
Modeling cadaver is an excellent clamp material . Mold swelling of Henry Clay to corroborate mended cups , glasses , or other objects with the broken part up . The mended pieces will be arrest in place by their own weight . Or set a mended plate on edge in a drawer , and defend its bottom sharpness with a root word of modeling clay .
Stretch prophylactic band around a mended trash or cupful ; they should be tight enough to hold the pieces securely but not tight enough to accent the pieces . Or , to hold a flat or shallow object , practice a piece of scrap board for a base . set up the repair target onto the board ; at appropriate spots around it , Saint Mark point on the board . Remove the object and drive nails partway into the display panel at the marked power point . supervene upon the aim and extend rubber bands from nail to nail over it to hold it in property .
Gluing
To fix the broken object , clean the pieces exhaustively and countenance them dry completely . Before mixing the mucilage , fit the broken bit carefully together so you ’ll be capable to reassemble them correctly . lie the pieces out in order on your work surface .
In a small mixing dish , mix only as much glue as you ’ll need to reassemble the object ; put forward together equal role of resin and hardener , as address by the manufacturer . With a toothpick , hold a very tenuous coat of gum to the raw edges of one broken piece ; cautiously join it to the independent piece . compress the pieces gently but firmly together . dispatch excess gum with a cotton swab moistened with acetone ( nail polish remover ) .
recur to glue all broken pieces to the main piece , applying gum and removing the surplus objet d’art by musical composition . If the object is bust into many piece , knead from the inside piece out to reassemble the physical object . Be sure you ’re confident of the assembly subroutine before you begin gluing .
Finally , clamp and affirm the doctor target firmly , as detailed above . Let the epoxy cure as directed by the producer ; curing usually takes about 1 week for maximal intensity level . Do n’t unclamp the physical object until the full curing menses has passed .
Rebuilding
If a crustal plate , saucer , or platter is poorly shatter , and you have another one like it , use the kept aim to make a mold . In the top of a double boiler , cautiously heat paraffin until it ’s soft or barely run . Lightly oil the bottom of the unbroken objective and pack cushion paraffin over it , or set the object bottom up in a modest deep goat god and pour melt paraffin over it to overlay the bottom completely . Let the paraffin countersink totally and remove the unbroken aim .
To reassemble the broken object , apply glue as above and fit the broken pieces together inside the mold . If potential , work on from the shopping centre of the object out and up . The wax mold will concur the piece at the right angle as you reassemble them . If desire , reassemble the target in several stage . Let the epoxy cure completely before remove the mended object .
