Not illustrated. 1905 edition. Excerpt: ...water necessary to balance one cubic inch of the respective metals. Tenacity of metals is ascertained by observing the weights required to break wires drawn through the same orifice. They stand in the following ratio: Iron, 269 Gold, ... 68 Copper, --157 Tin, -24 Platinum, --124 Zinc, IS Silver, -85 The different metals become fusible, or melt, according to Prof. Daniel's pyrometer, at the following degrees of wmperature: MBTAL. fAHBBHHRIT. C1NTI&RADB. Bismuth, .... 497 258 Copper, 1996 1091 Gold, Iron, cast, ...-2786 1630 Lead, .... 617 826 Nickel and Iron, wrought, high-est heat of forge. Platinum, not fusible in ordi-nary furnaces. Silver, .... 1878 1023 Tin, 442 228 Zinc, 778 412 Alloys of metals vary from the mean melting point oi the metals of which they are composed. They usually melt at a lower degree of temperature than the mean, and sometimes at a lower degree than either of the metals of which they are composed, as for instance, tin solder, composed of two parts tin and one of lead, melts at about 360 F. A hard solder, composed of two-thirds silver and one-third spring brass, melts easier than either the silver or the brass. APPENDIX. Mats to hold the work on, while being heated, are now made of charcoal cut into rectangular pieces and chemically treated to prevent burning when not in use. A valuable improvement. They are also made of asbestos for special purposes, as for holding dental plates, spectacle bows and for melting small bodies of metals. Magnesia blocks and carbon blocks are also used by jewellers. Attach to your mouth blowpipe a steel point, projecting beyond the bend, to touch fused solder that does not go where you want it. When it is necessary to use alcohol the article made from wood answers the purpose and i

Soldering, Brazing & Welding is an ideal manual for anyone requiring comprehensive advice and instruction in these common forms of metalwork. Their applications are now increasingly widespread in the craft of metalwork, as well as more traditionally in light industry. Topics covered include procedure for making a soldering joint; selecting consumables and heat source for silver soldering; typical braze welding techniques and applications; oxy-acetylene equipment, setting up, and fusion welding; and MIG, TIG, and manual metal arc welding.

'A Practical Guide to Distilling Alcohol from Farm Products' by F.B. Wright is the go-to resource for farmers and manufacturers interested in making industrial alcohol from their crops. Readers will find a collection of US denaturing formulas, distilling apparatus, malting, and alcoholometry, and learn how to prepare mashes and fermentation. This comprehensive guide is essential for farmers looking to turn their produce into a new means of income, and for manufacturers seeking to substitute hydrocarbon fuels.
