Yellow Colored Pyrex Mixing Bowls and other items in general are one of my favorites because of their sunny disposition! They and the Turquoise 400 bowls usually run about the same prices, slightly under the Pink 400 bowls set.

These Yellow pyrex mixing bowls came in sets of 4 pieces, but I believe that you often find orphan bowls that are not actually from an original set of 4 since the yellow color was used in other sets like the “Verde” and Primary Colors set. Also, remember that it was also released later as a three bowl set (300 series) without the 4 quart size. But for the early 4-piece set the sizes are: a 1 1/2 pint 5 1/2 inch diameter, 1 1/2 quart 7 inch diameter, 2 1/2 quart 8 1/2 inch diameter, and a 4 quart 10 inch diameter bowl.
