When bonding together clay pieces both mating edges should be roughly scratched with a sharp edged tool like a fettling knife or a fork.  This creates rough, grippy surfaces.  Then slip(sticky wet clay) is generously applied to the scored surfaces and they pushed together and smoothed.  Additional clay may be added to complete the bonding process.
