Vintage Pyrex Mixing Bowl Sets: Every Set Explained
One of the first questions new Pyrex collectors ask is: what are the different bowl sets, and how do I know if I have a complete one? Corning made several distinct nesting bowl systems over the decades. Here’s a complete guide to all of them.
The Two Main Bowl Systems
Vintage Pyrex nesting bowls come in two distinct shapes, each with its own model number series:
1. Round Nesting Bowls (400 Series)
The classic round mixing bowl set. The bowls stack concentrically with no handles.
| Model | Size | Capacity | Common Nicknames |
|---|---|---|---|
| 401 | Small | 1½ qt | — |
| 402 | Medium | 1½ qt | — |
| 403 | Large | 2½ qt | — |
| 404 | Jumbo | 4 qt | — |
The 400-series set typically comes in four bowls (401–404) in graduated sizes. Primary Colors is the most famous pattern in this series — one bowl each in red, yellow, blue, and green.
2. Cinderella Bowls (440 Series)
The cinderella bowl shape has two small side handles and a more oval profile. This is the shape most people picture when they think “vintage Pyrex.”
| Model | Size | Capacity |
|---|---|---|
| 441 | Small | 1½ qt |
| 442 | Medium | 1½ qt |
| 443 | Large | 2½ qt |
| 444 | Jumbo | 4 qt |
The cinderella shape was introduced in the late 1950s and became the primary vehicle for the decorated patterns — Butterprint, Gooseberry, Lucky in Love, and most other patterned sets are in this shape.
Primary Colors: The Original Set
Primary Colors (1945–1986) uses the round 400-series bowls and comes in four colors:
- 401: Red
- 402: Yellow
- 403: Blue (sometimes green)
- 404: Green (sometimes blue)
Color assignments for 402/403 varied by era and production run. Early sets have the blue in the 402 and green in the 403; later sets may swap these. A complete 4-bowl primary colors set in good condition runs $80–$160 depending on color brightness.
Cinderella Bowl Patterns: The Collector Favorites
Most decorated pattern sets use the cinderella (441–444) shape. Key complete set values by pattern:
| Pattern | Complete Set (Mint) | Complete Set (Good) |
|---|---|---|
| Lucky in Love | $1,800–$3,500 | $900–$1,800 |
| Atomic Eyes | $1,100–$1,800 | $550–$1,100 |
| Constellation | $950–$1,500 | $475–$950 |
| Pink Stems | $800–$1,300 | $400–$800 |
| Town and Country | $430–$730 | $215–$430 |
| Butterprint | $160–$250 | $90–$150 |
| Gooseberry | $140–$220 | $70–$140 |
| Spring Blossom | $120–$200 | $60–$120 |
| Friendship | $100–$180 | $50–$100 |
| Autumn Harvest | $90–$160 | $45–$90 |
Finding Your Set Number
Every vintage Pyrex bowl has a model number stamped on the bottom. The number tells you both the shape and the size:
- 401–404: Round nesting bowls
- 441–444: Cinderella bowls
- Single digits or 3-digit numbers starting with 0 (043, 045, etc.): Casseroles
If your bowl doesn’t have a visible number, the shape is usually enough to identify the series — round bowls are 400-series, handled oval bowls are cinderella.
What Makes a “Complete” Set?
A complete cinderella bowl set is four bowls: 441, 442, 443, and 444, all in the same pattern and all in matching condition. The set is considered incomplete if:
- Any of the four bowls is missing
- Bowls are in significantly different condition states
- The pattern or colorway doesn’t match across all four
For patterns with lid options (some casseroles and refrigerator dishes), the lid adds significant value — a covered casserole with its original matching lid is worth considerably more than the piece alone.
Tips for Completing a Set
If you’re missing one or two pieces from a set:
- Note the exact model number of what you need (441, 442, 443, or 444)
- Search eBay for just that piece with the pattern name and model number
- Check condition carefully — mixing noticeably different-condition pieces in a set is visually obvious
- Join Pyrex collector Facebook groups — members regularly sell individual pieces to complete sets
