			Hi Jeff, Nice to hear from you, and to see your nice tulwar, with a blade well used. The armoury mark is one of the more clear ones. The number on yours is 181, which you probably know already. On mine the number is 2. I have yet to find out what the letters say/mean, but this will no doubt be difficult, as they are likely to abbreviations. |

			Hi Jens, Thanks for posting this topic. I had a Sikh friend read the script and he said the letters read (phonetically) "ra - khee - Ka", good luck finding out what that means  . Of course it may read completely different in Rajasthan. All the best Jeff |

			Hi Jeff, If a collector thinks it is difficult to find a nice tulwar, to clean it and to etch it, it is nothing compared to the effort it takes to find someone who can/will translate the abbreviated letters  . Is the armoury mark the only decoration on the blade, and is the decoration on the hilt in relief or flat? All the best Jens |

			Hi Jens, I know what you mean about getting translations, don't get me started!  . The hilt has raised images, I think it is an iron hilt with a silver wash. The strange thing is the patina is a darkish blue rather than black? The blade has one other worn mark, I will post it below. All the Best Jeff |

			Now that I look at the enlarged picture it looks like koftghari on an iron hilt. I never noticed that before? Jeff |

  ) I picked up from Artzi a few years ago with silver fittings that have a rich blue, lusterous patina.  I imagine this has something to do with the alloy?  Perhaps Jose, or one of the metalurgists here can edify this for us. It looks black here, but in the hand, it's clearly dark blue.   | |

			I am not a plater but the plater I use for replating peoples tableware tells me that the metal of the item to be plated will effect the colour.  So when gold plating some objects a layer of copper is put on first to help the yellow gold.  Silver straight on to steel will be effected,  that may explain why even clean of oxidisation the silver has a blue hue.  As to Andrews dha I think it is probably the quality of the silver.

			There's many techniques to give a blue (or other) colour to a polished steel surface (you may be familiar with the term "bluing"). The basis of all of them is the formation of a (usually thin) layer of specific corrosion products that feature the colour of choice. This, of course, is different than painting, enameling, lacquering or other "covering" techniques, in that the idea is making the metal react chemically and produce a specific spices of compound with the right coloration. Depending on their nature, many of these layers have also some more or less effective protective properties in front of oxidation, combining aesthetics with functionality.

			My ears were burning until I got onto this thread...    Sterling or purer will oxidize a bluish black and then turn into a dark black as more oxidation accrues. |
