Abstract
The strength of ice is reduced by dissolving in water prior to freezing a composition of (A) a water-soluble polyhydroxy compound or monoalkylether thereof and (B) an alkali metal carbonate in an amount to provide an effective amount of (A) plus (B). The method is especially useful for application to particulate solids, such as coal and mineral ores, which are shipped and stored in masses exposed to freezing temperatures. Any ice that is formed is physically weak and will not deter the unloading of the thusly conditioned particulate solids.
