Pressure-melting of ice
The pressure-melting curve of ice is often found in literature deling with ice problems. This curve originates form the eexcellent experimental works of G. Tammann (1903) and P.V. Bridgman (1912). The method used means that ice at constant temperature is submitted to an external pressure. When incre...

The pressure-melting curve of ice is often found in literature deling with ice problems. This curve originates form the eexcellent experimental works of G. Tammann (1903) and P.V. Bridgman (1912).

Results from their works are summarized in this paper. An alternative experimental method was used in this study. Water is confined in a filled up pressure tank.
