Show Chemical Generator for Hot Water It has bas been shown that a certain combination of salts brings about the generation of ot heat By applying this chemical phenomenon a cheap and efficient efficient ef ef- ef warming bottle may be formed writes write's s S S. Leonard Bastin In the Popular Popular Popular lar Science Monthly First of ot all mix together sodium acetate and sodium In water using one part of ot the former to nine parts of ot the latter salt There should be a sufficient quantity of these materials to fill the earthenware bottle three parts full tull The vess vessel 1 should now be l loosely os IY and placed either In hot water or in an oven until the salts have completely dissolved For many hours after t this ls the bottle will radiate considerable heat To renew renew renew re re- re- re new the warmth giving properties it is only necessary to give the bottle a good shaking |
