58.5LBS Copper Nickel Silver Soldered Scrap Norte Dame Soup Tureen Serving Bowls
This is for a lot of 20 bowls that weight about 58.5 LBS. 20 bowls = about 46.8 oz per bowl. They do vary in weight. They are 5 ¼” Tall, the bottom is 6 5/8” in diameter, the top is 9 ¼”, and they are 10 ¾” wide if you measure at the handles.
These were special made for Notre Dame and used for many years there. I was told by the catering staff they have been in storage for at least 30 years. They are heavy duty and built for commercial use, in there day. In general they are called “hollow ware” or “hotel ware”.
These are beat up and worn from years of use. The silver plating is tarnished everywhere it’s just not fully worn off.
Some might take a rubber mallet to get them apart.
On most of them the stamp is mostly or fully worn off.
One with a full stamp reads:
UNIVERSITY OF NOTRE DAME
INTERNATIONAL SILVER CO
SILVER SOLDERED
SL 0810
96OZ
“31” in a box, this is a year stamp for 1931
In this lot of other types of dishes I have found stamps ranging from 1928-1937.
These bowls are made by stamping a rolled plate to a bowl shape. Then a cast rings, top and bottom, were silvered soldered to the bowl. Then the bowl is silver plated. So if you following this metal comes from 4 sources; a rolled plate, a casting, the silver solder, and solder plating. The plate and casting are German silver about 20% nickel, 20% Zinc, 60% Copper.
On one random piece I read the plate with a XRF Spectrometer gun and it looks to be all refined metal. I read on the edge where the plate is soldered to the casting. This part is showing a little gold, rhodium and iron. Don’t count on this, it’s just one random part from someone who has no experience using the gun. It’s still quite interesting! From a number of tests and sources there is at least 1 % silver in these. I betting it’s more like 2% or more.
I have 1000's of lbs of this stuff
