According to Captain Bertrand R. Brinley's 1960 book, Rocket Manual for Amateurs, chapter 3, page 96-97, increases the power of an explosive as the cube of the weight. "Two ounces of an explosive is 8 times as powerful as one ounce. Three ounces is 27 times as powerful. Five ounces is 125 times as powerful."
We have seen how 3g 170°C hot liquid eutectic KNO3-NaNO3-Mannitol deflagrates. If this rule of thumb is true, 1kg liquid eutectic KNO3-NaNO3-Mannitol would be around 3333 = 36926037 as powerful as 3g. Difficult to imagine, but if it is even much less, hot liquid eutectic KNO3-NaNO3-sugar alcohol could be considered (and used) as an explosive. Solid eutectic KNO3-NaNO3-sugar alcohol is cheap, very easy to manufacture and safe to handle.
Liquid eutectic KNO3-NaNO3-sugar alcohol could be cast in an according heat- and pressure-proof container. The container would then be closed after the eutectic KNO3-NaNO3-sugar alcohol is hardened and encased with a heat up charge (end burner configuration). While the heat up charge burns away it would heat and liquefy the eutectic KNO3-NaNO3-sugar alcohol inside the container. It would need to be determined, which effect the pressure increase in the container has on the melting point of the KNO3-NaNO3-sugar alcohol. However, the pressure increase will increase the burn rate further.
Ignition of the liquid KNO3-NaNO3-sugar alcohol can be finally done by an electric match or reaching the auto ignition temperature of the sugar alcohol by the heat up charge.
