The cutlery is made up of a ____ called ____.
- Magnetic material, iron
- Magnetic material, steel
- Non-magnetic material, iron
- Non-magnetic material, steel
Hint:
Eating or serving with utensils made of silver, silver-plated metals or stainless steel is relatively recent.
The correct answer is: Magnetic material, steel
The raw material of silverware is stainless steel, sterling silver, or, in the case of silver-plate, a base metal (such as a high-quality copper alloy) over which a layer of silver is electrically deposited.
Stainless steel is a combination of steel, chrome and nickel. The finest grade of metal used in producing quality lines is 18/8 stainless steel. This means that it contains 18 percent chrome, 8 percent nickel. Stainless steel is very popular because of its easy care, durability, and low price.
