STEEL POINTS.
The expression "well-tempered" or "finely-tempered" steel is generally misused. It is usually taken to indicate steel of extra -hardness, whereas the reverse is the case, though'very few people are aware of the fact.
The greater the degree of tempering the softer the steel. The steel-worker measures the degree of tempering by the color of the metal. Thus the hardest —i.e., the least tempered-steelis light straw in color, while the softest kind is white. ' Between these extremes, commencing from the hard end of the scale, are the following shades: Straw, dark straw, light bronze, bronze, dark bronze, light blue, blue, dark brae.
Tempering steel is a very delicate business, and one calling for that sense of what is "just right" which., is found in good cooks.
