What is the name of the book by Rains and his fuse? John
Hallo Ivan,Hallo Ivan,
today the book reprint "Submarine Warfare, Offensive And Defensive", J.S.Barnes 1869, that I ordered in January, has at last arrived. Even for the price of 22,60 Euro it's worth it's money. It's a treasure trove if you are interested in the history of mines. I attach a foto of the article about Russia. I have seen the name of Professor Jacobi (an eminent russian chemist and philsopher) mentioned in other books before. He seems to be the inventor of the Sulfuric acid-Chlorate-Shugar fuse. You must have come across this name in your research. In the discussion about the finnish delay action fuze (iron wire-Sulfuric acid)a few days ago, I also asked about your valued opinion about it's first appearance. What do your historical sources have to say ?

Hallo Belifors,Hallo Ivan,
I had been hoping for your informed answer on my above question. Meanwhile I found some interesting info in a book on the life of Alfred Nobel, which I bought years ago at the Nobel Museum at the Bofors factory in Sweden. His father Immanuel Nobel emigrated with his family to St.Petersburg in 1841View attachment 81497View attachment 81496 and set up a big factory (up to 1000 workers) to manufacture sea-and land-mines for the Zar of Russia. Attached are 2 fotos from the swedish book.

Hallo Ivan,
do you have pictures of Imperial Russian victim actuated (not manualy by observer) land mines before 1850 and pictures of the Nobel land mines ? From what date is the earliest description of the Sulfuric Acid / Chlorate-Shugar fuse (Professor Jacobi named as inventor in western literature) that you could find in Russia ? What is the earliest description of the so called "Finnish Fuze" (wire corroded by acid) that you could find ? I'm very much interested to hear your answer on this questions.

Thank youu for your answer Ivan. Do you have any technical drawing/description of the landmines/fuzing of Golovinski and Navaganski and the mercury contactors ? By the way, in the swedish book it is mentioned that Nobel produced 2 types of mines, an electric (galvanic batterie) fired one and a pyrotechnically fuzed one. The name "Fugas" you use for old land mines, is this the same as "Fougasse", a hole in the ground loaded with powder and stones or grenades as projectiles, which were always command fired manually, not victim actuated ?

Hallo Ivan,
when you speak of Mercury, do you mean the explosive salt Mercury Fulminate or the pure liquid metal Mercury ? The terminology on this subject is very important. A "Fougasse" is an old (probably used since the 16th century) earth/stone mortar. The word "Mine" originates from the subterranean mines of old and miners were the men that dug the shafts and tunnels. So these experts were the ones to be first used to construct explosive "Mines", tunnels dug under a fort and a powder chamber filled with black powder, to blow up a fort. Ignition for both was the same, a lead-fire tube. So MINE = underground explosive charge and "Fougasse"= mortar in modern usage. These underground dug "Mines" were probably in use since the 12th century. What I'm still searching for, is the first employment of a victim actuated land mine which reacts on a man stepping on to it. I thought, up till last year, that the "Rain's Fuze" (US civil war) was the first, but, the above mentioned literature sources tell of russian employment already around 1840. If you believe, that Professor Jacobi was not the inventor of the H2SO4-Chlorate/Shugar igniter, who was the inventor of its use in mines ? This must have occured between 1789 (B.Pelletier's realization of the reaction) and 1840 (published use in mines in russia). You mention electric mines by Jacobi. Do you have any drawings of those ?

When I speak Mercury I mean only liquid metal Mercury, not any explosive with Mercury or some another combination with Mercury. Because Mercury Fulminate is Mercury Fulminate
Yes-yes, I agree with your notes about "fougases" and "mines". Sorry, if you were confused, but whet I wote "fougase" I mean only like land-mine. Sea or tiver is another mine and if what - I`ll write what exactly I mean, because I know about thist synonyms. And if it stone fougase I`ll write what exactly it is.
I think Rain`s fuse wasn`t first, because Jacobi or Nobel was first. It was or Jacobi or Nobel. Sorry, but I`m not very big specialist in sea mine and can`t tell you exactly about difference between Nobel and Jacobi sea pyro mines. I`ll check it!
I heared a lot of times, that Jacobi found this combination - H2SO4+Chlorate/Shugar igniter, but really could be Nobel made it first. Could be and this - Jacobi was Russian engineer, but Nobel not and in country was politic "own inventors". I`ll try to check it!

Mercury used like electrical contactor between two contacts. Were a lot of different combinations. Sometimes Mercury was in glass tube, which crashed by vessel when it bited mine. Sometimes tubes chashed tube metall balls. Mercury was very popular and used in Russian contactor for land-mine during WWI.Thank you very much Ivan for your most informed answers meanwhile. I have another question : How was the Mercury used ?
