It can therefore be said that in orderto obtain the best and most desirablebriquettes an ISfb mixture should be used. Tabulated the reasons are: I. The briquettes have thegreatest strength in relative proportionto their mixture. II. They have a fine appearanceand do not crumble and chip. III. When broken do^7n in structurethe particles are rigid pieces iThich stillretain the firing qualities. IV. The mixture used in theircomposition is easy to handle,is plastic,anddoes not stick to the mould. 78. Coke Breeze Briquettes After Cokin= 79 COMBUSTIBILITT. One hundred pounds-of the briquettesv;ere They -rere made fron an18fo mixture,and under the standard com-pression load of 3500 pounds. They werethen colred in the oven. The ooked briquettes were then burntin a common house hot air furnace. Theywere kindled with wood and treated in norespetts different than were then anthracitecoal. The briquettes ignited quite easily. They burnt uniformly on the ,the fire atalT st^iges of combustion beinguniform throughout. When the draft was fullopen they glowed brightly emitting a blueflame whose length never exceeded two heat given off was intense. TrTnen thedrs^ft was shut off they glowed with red were subjected to a small draft foreight hours after whihh time the fire was 80 Combust itoillty still burning. The draft v;as tlien increaseda little and they OQntinued to burn untilonly a fev» small isolated particles \7ereleft.
