BLOWPIPE: Mouth | Perfect for scientific demonstration

BLOWPIPE Mouth

• This Blowpipe is made of nickel plated brass 200mm long.
• The end that is blown into is rounded to avoid damage to the mouth.

(Wikipedia excerpt: ..."If a stream or jet of air is directed through a flame, fuel air mixing is enhanced and the jet exiting the flame is intensely hot. Jewelers and glassblowers engaged in lampwork have used the blowpipe (BP) since ancient times, with the blast being powered by the user's lungs. For small work, a mouth-blown (BP) may be used with a candle flame or an alcohol lamp, with established techniques for applying oxidizing and reducing flames to the workpiece or specimen. Starting in the late 18th Century, (BP) have been powered by mechanisms, initially bladders and bellows, but now blowers, compressors and compressed gas cylinders are commonplace.

While blowing air is effective, blowing oxygen produces higher temperatures, and it is also practical to invert the roles of the gasses and blow fuel through air. Contemporary blowtorches and oxy-fuel welding and cutting torches can be considered to be modern developments of the (BP) . Kit for (BP) analysis Carl Osterland, Freiberg, c. 1870

In chemistry and mineralogy (BP) have been used as scientific instruments for the analysis of small samples since about 1738, according to the accounts of Torbern Bergman. One Andreas Swab, a Swedish metallurgist and Counsellor of the College of Mines is credited with the first use of the blowpipe for 'pyrognostic operations', of which no record remains. The next person of eminence who used the blowpipe was Axel Fredrik Cronstedt, who put it to the purpose of the discrimination of minerals by means of fusible reagents...")
