A method of making a heat cell comprising a particulate exothermic composition, wherein the method comprises the steps of: (a) constructing a particulate premix composition having a premix cell weight of from 0.4 grams to 2.5 grams, wherein the particulate premix composition comprises: (i) from 10 percent to 90 percent by weight of iron powder; (ii) from 1 percent to 25 percent by weight of a carbon selected from the group consisting of activated carbon, non-activated carbon, and mixtures thereof; (iii) from 1 percent to 25 percent by weight of an absorbent gelling material; and (iv) from 1 percent to 10 percent by weight of water, wherein the median particle size ratio of absorbent gelling material to iron powder is from about 3:1 to about 1:3, and (b) dosing a brine solution onto the pre-mix composition. Also disclosed is the heat cell obtained by said method.
