Sounds good. My problem was with the word 'float'. Obviously, the bar floats neither in air nor water, but rather sinks or, as in this particular case, simply hangs or is suspended.
fatso, you must describe your testing technique in detail for us to be able to determine the quality of the results. The seemingly high density may be within the range of accuracy for your method/instrumentation. Also, it's possible the bar may be pure silver and yet still be a fake if it's purporte...
One final observation, I suspect the handles are hollow and therefore your specific gravity test is useless in this case. I make this suggestion based on the low density you recorded. Usually nonferrous silver-plated objects have a density near 9 g/cc. .
I believe I would call your loving cup a sugar bowl. Did you also test a known silver object? Doing a single measurement on an apparatus is no way to conduct a test. ;) .
How nice to have such cosmopolitan neighbors! I suggest taking it to an expert in middle eastern scripts. Also, it's possible the artisan was illiterate and the 'script' is purely decorative.;)
About the 'water test' (specific gravity), I'd like to say that a much better measure of volume is obtained by weighing the item suspended in water and noting the the difference in weight [when suspended in air]. That difference in grams is approximately equal to the displacement in cubic centimeter...
