Science Buddies: "Ask an Expert"

Hi,

Just wondering how the exothermic of sodium acetate that has been supersaturated in water (with use of a catalyst) used in hadn't warmers can be extended. Currently only gives out heat for around 1hr, was wondering what could be done to increase this time.

thanks
