Pyrex Prepware 2-Piece Glass Measuring Set Review (2026)
In-depth review of the Pyrex Prepware 1 and 2-cup glass set: nonporous glass, heat tolerance, stacking, and where a 2-cup ceiling bites.
Pyrex Prepware 2-Piece Glass Measuring Set, 1 and 2-Cup
The classic glass liquid set: a 1-cup and a 2-cup jug in nonporous glass that goes from microwave to freezer and stacks for storage.
Our verdict
The Pyrex Prepware 2-Piece Set is the best measuring cup set for most kitchens, because it does the liquid job with no fuss: clear glass you can read through, heat tolerance that covers melting and reheating, and two sizes that match the recipes people actually cook. It is breakable and it tops out at 2 cups, but for everyday liquid measuring those are acceptable limits, and the set costs little enough that replacing a broken cup is not a crisis.
What we like
- Nonporous glass will not warp, stain, or absorb odors, so the cups stay clear and neutral through years of use.
- The glass is preheated-oven, microwave, fridge, freezer, and dishwasher safe, so you can melt, mix, and store in the same cup.
- Two sizes cover the common liquid range: the 1-cup for dressings and small amounts, the 2-cup for most recipes.
What to watch out for
- Glass is breakable, so a drop on a tile floor can end a cup that a steel or plastic cup would survive.
- The 2-cup top size is too small for large batters, soups, or stock, where a 4-cup jug is needed.
- Reading the level means lifting the jug to eye level, which the angled OXO cup avoids.
Who it is for
Everyday cooks who measure liquids daily and want a glass jug that can melt, mix, and store in the same cup.
Why glass still wins for liquids
Glass is nonporous, which is the whole argument: it will not warp, stain, or absorb odors, so a cup that measured tomato sauce yesterday measures milk cleanly today. The same property makes it the easiest material to keep honest, since you can see the level through the wall and see whether the cup is actually clean. Plastic clouds and steel hides the level; glass does neither, which is why it remains the default liquid material after decades.
Heat tolerance is the quiet advantage
The set is rated for a preheated oven, microwave, fridge, and freezer, which turns the jug into a small prep vessel: melt butter in the microwave, measure the rest of the liquids into the same cup, and pour once. That saves a bowl and a transfer, and it is the use case that separates a Pyrex jug from a plastic cup that cannot take heat at all. The trade is fragility: glass on a tile floor is a real risk, and the 2-year limited warranty covers defects, not drops.
How it stacks up
Against the Anchor Hocking 3-Piece Set, Pyrex wins on compactness and stackability, while Anchor Hocking wins on size range with its 4-cup jug. Against the OXO Angled 2-Cup, Pyrex wins on heat tolerance and clarity, while OXO wins on reading the level from above without lifting the cup. Against the Anchor Hocking Lidded Set, Pyrex wins on price and simplicity, while the lidded set wins for anyone who measures ahead and stores in the fridge. Pyrex is the default; the others are answers to specific needs.

Questions, answered
Can the Pyrex cups go in the dishwasher?
Yes, they are dishwasher safe. Hand washing keeps the red graduations bright for longer, but dishwasher cycles will not damage the glass itself.
Do the two cups stack for storage?
Yes, the set is designed to stack, so the 1-cup nests inside the 2-cup and the pair takes the shelf space of one jug.
Is 2 cups enough for most recipes?
For most everyday cooking, yes: sauces, dressings, batters, and drinks rarely exceed 2 cups. Large soups and scaled-up baking need the 4-cup jug from the Anchor Hocking 3-piece set instead.
