Welcome, and thank you for your contribution.
Well it seems that you are a really Â»new-bÂ«: Sorry there fore to must say this, your statement includes totally wrong conclusions!
Indications on American or British Plated hollowware and flatware by use of Â»Super A1
Â« as Â»larkfield
Â« reports, Â»AI
Â« as in the question, or Â»A1
Â« and Â»A2
Â« as you report, are only factory statements of a kind of silver plating quality
= weight of pure silver (normally of 999-1,000
fineness) is used for plating several amount of flatware surfaces obverse and reverse, or by hollowware: inside and outside.
In the American or British areas in the past two centuries, since about 1843
Electro Plating was start to be used instead of the former Â»Sheffield Plate
Â« technique, hasn't existed any official rules of how much silver must be used on how much surface, and who should it be indicated!
As often it is, the only ruler was the Â»commerceÂ«, Â»concurrencyÂ«, and the Â»marketÂ« itself as well.
Some producer, maybe after have dipped only a second time for some seconds the objects in the galvanic bath
used the indication of to be: Â»DOUBLE PLATED
Â« - others followed
by Â»TRIPLE PLATE
Â«, and Â»QUADRUPLE PLATE
Items of this past time COULD
include the curiosity that a Â»DOUBLE PLATEDÂ« is of better plated quality as a Â»QUADRUPLE PLATEÂ«.
So, as collector novice you must learn; and handle a lot of pieces — buy less, but buy quality.
The Â»ContinentalÂ« or West European producer had similar wrestlings — after First World War e.g. the big German producer WMF and Wellner had on that theme their own expensive “war”, lasting for years.
Please look to and read these:
Now to your statement of: Â» is in reference to the thickness
of the silver plating, eith 0.800
Â« never any body of the producers has warranted by indication numerals or letter-numeral! All indicated there with only a Â»kind of warrantyÂ«, to have used some pure silver by the electro plating processing.
Well, thickness stand in relation to the weight of material, by same dimension of surface = in Western Europe’s past it was used 90 gram on a quarter part of a square meter. Before World War II it became usual, to use 100 gram. Now it’s there normally used on better plated quality cutlery 150 gram.
2. As already mentioned, by the electro galvanic plating processing is placed on the Â»Anode
Â« pure silver of normally 999-1,000
Your stated 0.800
would result in so many problems; that these degraded finenesses never were used in a “normal” electro galvanic plating process.
Well, on the old Â»Sheffield Plate
Â« production processing it was possible, using for the obverse of the basic copper plate several compositions of silver alloy
— but that is another theme.
For final another curiosity: Most often cutlery, and seldom hollowware as well, made from silver alloy of fineness 800-1,000 upwards gets by some producers a final electro galvanic layer of silver with 999-1,000 fineness. Be made for better appearances of shining, and for the surfaces durability; by use of a very special galvanic technique, called Â»hard silverÂ«.
