Nitrogen cycling in western India as revealed by nitrogen isotopes, and the historic production of saltpetre
Saltpetre (KNO 3 ) manufacture was a principal monopoly industry in early Modern India when the United Kingdom governed the social and economic systems. The process represented microbial transformation of excrementitious livestock and human wastes deposited around habitats, resulting in formation of salt efflorescence at an economic scale. Low caste people collected these wastes for extraction and production of rough saltpetre under the administr…
Volcanic native sulphur pebbles excavated from the near-shore deposits of Hakata Bay, Kyushu, Japan
Reworking saltpetre manufacture in Lao PRD
Anthropogenic saltpetre
Saltpetre constitutes one of the major ingredients of gunpowder, which was a driving force during the political changes in late medieval to early modern times in Japan. Two types of model saltpetre mineralization are studied. One represents efflorescent saltpetre formed as the byproduct of indigo dye manufacture, whereas the second is anthropogenic, derived from relict nitre‐beds. Here, oxygen and nitrogen isotopic analysis, as expressed by δ 18 …
Historic commodity of sulfur prevailed during the early to middle 19th century in Japan
Oxygen and nitrogen isotopic constraints to the origin of saltpetre in historic gunpowder prevailed during the 19th century in Japan
Historic saltpetre of British Indian origin
The Provenance of Historical Gunpowder from South‐Western J apan
Stable isotopic analysis was undertaken for the gunpowder ingredients from crude saltpetre and propellants from several types of gun that prevailed during the late 19th century in south‐western J apan. Stable isotopic signatures for δ 15 N saltpetre nitrogen , δ 34 S native sulphur and δ 13 C charcoal carbon in crude saltpetre, gunpowder magazines bearing the trademark of mills from southern S cotland and cartridges for an improved S harps rifle …
A stable isotopic constraint on the origin of sulphur ore excavated from the exotic four‐lobe jars that prevailed during late medieval to early modern times in S akai ( O saka), south‐western J apan
Stable sulphur isotope ratios were determined for native sulphur ore that was excavated from exotic four‐lobe jars in S akai, south‐western J apan. The jars were buried after a fire event that occurred on 28 A pril 1615. The sulphur isotopic results (average δ 34 S = +0.5‰) were evaluated in terms of comparing ancient documents with a database from new sulphur collections. The origin of the sulphur ore is estimated to be transportation from nativ…
The stable isotopic composition of historical black powder applicable to a J apanese T anegashima matchlock
The objective of the present study is to employ stable isotope ratio measurements (δ 15 N, δ 34 S and δ 13 C) of the nitrogen, sulphur and carbon in black powder (a mixture of saltpetre, native sulphur and charcoal) as a means of source identification. A sum total of 20 samples of historical black powder applicable to matchlocks were collected from six locations throughout J apan. This classic type of hand gun prevailed up to the introduction of …
Stable isotopic characterization of gunpowder ingredients from the mid to late nineteenth century in Japan
Ecological variations in diatom assemblages in the Paleo-Kathmandu Lake linked with global and Indian monsoon climate changes for the last 600,000 years
Variations in fossil diatom assemblages and their relationship with global and Indian monsoon climate changes for the last 600,000 yr were investigated using a core of ancient lake (Paleo-Kathmandu Lake) sediments drilled at the Kathmandu Basin, Nepal Himalaya. Chronological scales of the core were constructed by tuning pollen wet and dry index records to the SPECMAP δ 18 O stack record. Examinations of biogenic silica contents and fossil diatom …
