We supply ceramic restorers in museums cyanoacrylate for repairs, medium thickness, the only reason they dont use it every time is that its hard to undo the joints compared to our conservation cement
Conservation cement is like a balsa cement but a different polymer, it is the most used in museums and by antique restorers for ceramics, non yellowing and heat & water proof, takes about 5 to 10 minutes to set
Epoxies , some yellow, some dont! , its down to the exact formula, ours doesnt yellow with age or heat unless heated above 160C
