Abstract. The maximum superheating of a solid prior to melting depends on the effective dimen-
sionless nucleation energy barrier, heterogeneities such as free surfaces and defects, and heating rates.
Superheating is rarely achieved with conventional slow heating due to the dominant effect of hetero-
