Here, we present a protocol to demonstrate the generation of ice when water is introduced to a cold bath of brine, as a secondary refrigerant, at a range of temperatures well below the freezing point of water. It can be used as an alternative way of producing ice for industry.

The present protocol describes the maceration and cleaning of cadaveric bone with a vacuum-sealed, hot water bath immersion technique. This is a low-cost, safe, and effective method to produce anatomical specimens for surgical planning and medical education as an alternative to three-dimensional (3D) printed models.

States of Water

Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart. Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...
FAQs
The key cooling mechanism is latent heat absorption. As ice melts, it takes in energy transferred from the surrounding reaction mixture or equipment without immediately producing a large temperature increase in the bath. This allows the system to absorb heat while remaining near its low operating temperature, making cooling more controlled than relying on a rapidly changing cold environment.
Water distributes transferred heat throughout the bath, helping reduce localized temperature differences around the material being cooled. The combination of water circulation within the mixture and energy absorption by melting ice supports relatively even cooling. This uniformity matters when a reaction mixture or piece of equipment must be cooled consistently rather than exposed to uneven thermal conditions.
An exothermic reaction releases heat, which can raise the temperature of its surroundings and affect reaction control. Surrounding the reaction mixture with an ice water bath provides a heat-absorbing environment that moderates this rise. By limiting excessive warming, the bath can improve safety and help maintain more consistent conditions during temperature-sensitive chemical operations.
Cooling with an ice water bath can support the formation of crystals or precipitated products from a reaction mixture. Lowering the mixture's temperature creates conditions that may help the desired material separate from the mixture. This application is useful when the experiment aims to obtain a solid product, and controlled cooling can contribute to more consistent experimental results.
The material requiring cooling is brought into contact with the ice water bath so heat can transfer away from it and into the bath. Depending on the experiment, the target may be a reaction mixture or equipment. The bath is particularly useful when cooling must be controlled to protect temperature-sensitive compounds or moderate heat-producing chemistry.
Chemists may choose this cooling approach when an experiment requires a low, relatively stable temperature, moderation of an exothermic reaction, cooling of a mixture or apparatus, or support for crystallization or precipitation. Its value lies in combining temperature control with a simple setup, helping reduce thermal stress on sensitive compounds and improve reproducibility between experimental runs.
