The open capillary tube measures the temperature at which a wax rinses in an open capillary tube when heated, and the drop point method  is the temperature at which first drop falls from the thermometer. The open capillary tube method  is frequently used for natural waxes as Candelilla wax, Beeswax, etc. meanwhile drop point is used primarily for petrolatums and other microcrystalline wax.

Drop melting point of petrolatum wax is the temperature at which the material becomes sufficiently fluid to drop from the thermometer used making the determination under definite prescribed conditions. This test method covers the determination of the drop melting point of petroleum wax. It is used primarily for petrolatum and other microcrystalline wax.
