How to Repair Porcelain

When a fragile porcelain object chips or breaks completely, owners need to know how to preserve them with a DIY repair. The main processes in repairing porcelain are gluing and clamping. When gluing parts or pieces of porcelain, a proper base support may be necessary. When fixing a thoroughly shattered porcelain users need to know how to create a mold from an identical object, which serves as a base support and a guide in fitting the parts together. Repairing porcelain is easier when one knows the right materials to use and understands the process and the steps involved in repairing these treasured objects.

1. Preparing the Tools and Materials

Users need more than a clear epoxy glue to fix a broken porcelain or fine china. The table below shows the complete list of tools and materials as well as their usage.

Tools and Materials


Mixing Dish and Stick

As a container in which to mix a clear epoxy glue

Masking Tape

To hold parts or pieces together after gluing

Sand-Filled Pan/Modelling Clay /Scrap Board

As a base support

Clothespins /Rubber Bands/

To clamp parts together


As a post to tie the rubber bands

Paraffin Wax

As a mold

Clear Epoxy Glue

To fit the parts together


As glue applicator

Acetone or Nail Polish Remover

To remove excess glue

Cotton Swabs

Acetone applicator

DIYers need to note that some suggested items are alternative tools and materials. Reading through the process of repairing porcelain allows users to know which tools and materials they need for their particular porcelain repair project.

2. Preparing to Fit the Parts Together

One should thoroughly clean the parts of the broken porcelain, then dry them completely. Reassembling the parts without glue helps determine how to glue them later and in which order to lay them on the work surface.

3. Gluing the Parts of a Broken Porcelain Object

Using the mixing dish, stir equal parts of resin and hardener, mixing only as much glue as needed. With a toothpick, spread a thin coat of glue on the raw edges of a part of porcelain and gently attach it to its connecting part. Next, firmly but gently press the parts together, removing excess glue with a cotton swab dipped in acetone or nail polish remover.

Repeat the process on all parts until all are connected to the main piece of porcelain. As a rule of thumb, especially when the porcelain has broken into many pieces, work from inside out to reassemble the object.

4. Clamping Broken Porcelain Drinkware

Clamping the parts of a broken porcelain allows faster bonding when applying glue. To clamp parts of a porcelain cup, for instance, gently wrap strips of masking tape around the cup. The tape should have enough fit and pressure so the mended parts do not move or slip.

5. Clamping a Cracked or Shattered Porcelain Plate

Embed the largest piece of the broken plate in a sand-filled pan, with the broken edges of the plate facing upwards to make it easier to glue other pieces of it due to gravity. One can also use clothespins to clamp large parts, or use the sand-filled pan to hold already-glued teapot, pitcher, cup, and other drinkware in place.

6. Alternatives Tools for Repairing Porcelain

A lump of modelling clay can also serve as a base support when gluing a porcelain pitcher, cup, or other porcelain object. DIYers can also use rubber bands to hold parts together, providing support and pressure. When stretching a rubber band around a porcelain material, be sure that it is not so tight that it causes the glued parts to slip. To hold a flat or shallow object, a piece of scrap board as a base is also useful. Replace the plate and stretch rubber bands from nail to nail over the plate to hold it in place and provide pressure for faster gluing.

7. Rebuilding Thoroughly Shattered Porcelain Objects

Users who have an object identical to the completely shattered porcelain object can use the undamaged object to make a mold. To do this, carefully heat paraffin wax in the top of a double boiler, lightly oil the bottom of the undamaged object, and pour softened paraffin wax over it. Alternatively, place the undamaged porcelain object, with its bottom facing upwards, in a small pan, and then pour melted paraffin wax over it until the bottom is completely covered. When the paraffin wax has set, carefully remove the undamaged porcelain object.

Follow the steps in gluing the broken porcelain object mentioned above, while using the mold as a base support and guide in reassembly. Allow the epoxy glue to cure before removing the mended object from the mold.
