Ceramics conservators choose an adhesive depending on the ceramic they are working on. Ideally the adhesive should be slightly weaker than the ceramic, so that if the ceramic is mishandled and breaks again, this will occur along the line of adhesive rather than causing fresh damage in the ceramic.
Conservators might use a barrier layer on porous ceramics, to prevent the adhesive being drawn into the body. This would be of a similar consistency to the adhesive used for the job.
A common mistake on home repairs is using far too much adhesive. Here, just enough adhesive was applied to coat the edges of the break.
