I remember a discussion some time ago, about how to show the different damascene patterns in blades.
Everything - or almost everything - was suggested, from different fruit juices to ferric chloride – and all what is in between. I have no doubt that it all will work, but what did the Indians use? T.H.Hendley writes lime, which sounds like a good place to start, others are a bit more cloak an dagger about it, but in an old catalogue from the State Museum, Hyderabad the author M.L.Nigam writes: ‘The last stage was to bring out the grain or ‘Jauhar’ by applying thin powder or solution of alum or saltpetre (potassium nitrate). Have any of you used alum of saltpetre? If yes, how do you do it, and is it very strong – fast working? Regards Jens |

Actually I have used alum on a kard and it does being out the little subtlties. It is still in progress. What I do is have a dish with a little water and a lot more alum until it becomes a watery paste, heat the mixture, and apply with a brush or rag (use distilled water). It will take lots of time, but the results are interesting. Water and alum make a weak acid. Hope this helps. I would only use this with wootz from India or Persia.

Thank you for your answer. You write that the result is interesting; in what way do you mean this?
If it gives a weak acid, this means that it is easier to control, but takes longer time than if you use ferric chloride. Have you tried with salpeter? BTW Francoise Bernier, a Frenchman travelling in India around 1650 writes, that they, in order to keep the water cold when it is hot, put a handful or two of saltpetre in the water. Maybe it cools the water, but I wonder how healthy it is to drink the water. Regards Jens |

No, Jens, I never used saltpeter. What I have done is heat both solution and blade. This seems to speed up the process a little and still makes it quite controllable.

There was an urban legend in the military that in the middle of a battle somebody emptied the tea urn on the cannon to cool it; the barrel bent down.....
