Won't try again, huh? Miller was already sliding his gun around the rock in front of him when Mallory caught his arm and pulled him back. Gawd help us, Miller muttered.Fragmentation bombs, you said He lapsed into gloomy silence. He shook out his pack of cigarettes.Have one? Jus' daydreamin', boss he said easily.Jus' daydreamin'. Miller looked round at him, eyes cold and still and empty of all recognition, then he blinked several times and grinned, a cut and bruised hand automatically reaching for his cigarettes. Bitter-mouthed, savage, the American was swearing softly and continuously, oblivious to the pain as he pounded his fist time and again into the sharp-edged gravel before him.Ībruptly Miller's smile vanished and he nodded. Then he became aware of the low murmuring to his left, shifted round again. The gravelly earth beneath his elbows grated harshly as Mallory shifted his weight slightly, looked at the two men to his right, Andrea with his impassive face empty of all expression, Louki with the sheen of tears in his eyes. The sudden silence was curiously oppressive, louder, more obtrusive than the clamour that had gone before. The frenetic stammering of the machine-guns stopped abruptly and in unison, the sound sheared off as by a guillotine. He risked a quick peep round one of the boulders, eased himself back again.Eight, mebbe ten of them still down there, boss, he reported.The poor bastards are like ostriches-trying to take cover behind stones the size of an orange. Store ammonium chloride capped at room temperature and protect it from heat.I do not believe it, Andrea said flatly.You couldn't make a mistake like that, my Captain. The only detectable odor is burning wood.ĬAUTION: Ammonium chloride fumes can cause respiratory harm or an asthma-like allergy, so avoid breathing dust, vapor, mist, or gas. This process sounds nastier than it is, in practice, and although prudence dictates erring on the side of caution and working with plenty of ventilation, the process does not produce a noticeable smell either of ammonia or of HCl. The resulting chemical burn is identical to a heat burn in most respects. Ammonia diffuses away into the atmosphere, leaving the strong acid behind, which burns the wood. On heating, ammonium chloride decomposes into ammonia gas and strong hydrochloric acid (NH 4Cl → NH 3 + HCl). If you want to apply a maker’s mark or other repeated pyrograph to wooden goods, but can’t justify the expense of a custom branding iron, an indistinguishable effect can be achieved by applying a strong solution of ammonium chloride, for instance using a foam rubber stamp, followed by relatively mild heat.
