PRESS OF DANDO COMPANY PHILADELPHIA Copyright, 1911 E. I. du Pont de Nemours Powder Co. Wilmington, Del. Foreword LTHOUGH the explosive itself very naturally demands first consideration when blasting is to be done, the fact must not be overlooked that it cannot be properly exploded without certain materials and appliances especially designed for the purpose, and which are commonly known as Blasting Supplies. In addition to those articles necessary to develop the energy of a charge of explosives, there are other devices which, although they may not be absolutely requisite, contribute to safety, certainty and economy in the use of explosives, and these are also included in the category of Blasting Supplies. The importance of keeping Blasting Supplies up to the highest standard in every respect cannot be over- estimated, for the very best grade costs but a trifle in comparison with the charge of explosives with which they are used. It is poor economy to attempt to deto- nate explosives with an inferior article, for this always results in a considerable waste of the value of the explos- ives. More than a hundred years experience in the manufacture, sale and use of all kinds of explosives has taught us that the popularity of our products depends entirely on the results which consumers have with them. With this in view, we must, from a standpoint of good business, if from no other, recommend only a high quality of Blasting Supplies.251752 INDEX ADVANTAGES OF STRONG DETONATORS - 85 BLASTING BY ELECTRICITY - - - . . 5 BLASTING CAPS - - . - . - - 63 BLASTING MACHINES - . - . 29 BLASTING MATS - ... - - 82 BLASTING SUPPLIES AND THEIR USE - ... 1 CAP CRIMPERS - . . . - . .

They consist of a copper capsule, or shell, containing a detonating charge surrounding a fine platinum bridge, which joins the tips of two insulated copper wires of various lengths. The ends of the copper wires are secured in the copper shell by a composition plug, which also serves to keep moisture and water away from the charge. The Electric Fuzes . electric fuze is detonated when sufficient current is passed through the 5 copper wires, and across the ill platinum bridge, to heat the latter to a temperature high enough to ignite the charge surrounding it. Delay Delay Electric Fuzes can be used to advantage in certain classes of tunnel or shaft excavating. These Electric Fuzes . are made so that a very short space of time intervenes between their ignition by the electric current and their detonation. By their use, it is possible, with but one opera- tion of the blasting machine, to fire one section of a blast, sufficiently ahead of the following section, for the material in the first to be out of the way when the next is blasted. When several charges of explosives are to be detonated at one time with electric fuzes, it is neces- sary unless the electric fuze wires are long enough to reach between the bore holes to join them with Connecting Wire. Insulated copper wire is used for this purpose...
