F.B Rogers Silver was manufactured from 1883 to around the early 1890's when the company was sold to William Rogers Mfg. Co. and became the West Silver Co.
In 1925, when the company was again sold to partners William Davison, Carleton A. Woodward, and H.E. Nearing. the name was changed back to F.B. Rogers and production continued under this name until 1955 with the company's merger to The National Silver Co.
Only appraisal of the actual pitcher might give indication of it's manufacture date. I've seen model 1707 pitchers sell on eBay for less than $30 though, which gives the indication of a later production date.
the silver is displaced out of the compound because the copper is more reactive. It becomes copper nitrate.
If the silver nitrate is in aqueous solution and the copper is solid in contact with the solution of silver nitrate, copper atoms will dissolve as ions from the surface of the copper and be replaced by silver atoms formed from the silver ions in solution. This reaction will continue until the entire surface of the copper in contact with the solution is covered with silver. The chemical driving force for this reaction is displacement of one element from its compounds by another element that is higher in the electromotive series than the element displaced.
Suspend a copper wire in a solution of silver nitrate. Over the course of a few hours the silver nitrate will convert to copper II nitrate, turning the solution blue. Elemental silver will precipitate.
from what I've seen, if the reaction is being done in distilled water, then the copper attracts the silver nitrate to it and the copper gets a thick film that is very easily removed and leaves tarnished copper looking bright and brand new.
A displacement reaction, in which the copper dissolves to form copper nitrate and replaces silver ions in the original silver nitrate, reducing the silver ions to metallic silver.
number of electrons capable of freely moving in the outermost shell of an element. eg. Copper
it is the pattern #
It's a purity mark, which indicates what percentage of silver is in the item. In that specific case, the piece is 96.2% silver, and the remainder is probably copper.
As copper is more reactive than silver copper will displace silver and will become copper nitrate and silver is left by its own from the reaction
Silver pitcher marked F.B.R. Taunton Mass with a lion passant and cross also number 848. Is it silver?
copper will replace silver in silver nitratesolution will precipitate silver and oxidize copper turning to copper nitrate
Sterling silver is stamped 925 or .925 because it is 92.5% silver, and 7.5% alloy (usually copper).
Copper and gold.
No, "chariots of silver and copper" is not an idiom. It may be used literally to describe chariots made of silver and copper.
Silver is almost twice as heavy as copper.
Copper and Silver are both elements. However the copper and silver objects you find in everyday life are unlikly to be 100% pure copper or silver. These objects will be made with copper or silver alloyed to other metals to improve its properties or decrease its cost.
No, copper replaces silver because it is more reactive than silver, and therefore more stable in a compound.
