Raised markings are molded into the glass and readable by touch, while etched markings are cut or chemically formed into the surface — and neither should fade, though plenty of decorated cups do.
A scrub pad, a hot dishwasher cycle, and a stack of cast-iron can all conspire against a measurement line, and the cup that reads “1 cup” today can read nothing six months from now. Whether the marking survives depends less on the word on the box than on how the line was actually made. The test below takes about ten seconds, and it tells you what you have before you buy it.
How Do You Tell Raised, Etched, and Printed Markings Apart?
Drag a clean fingernail across the graduation line: a molded number catches your nail on a physical ridge, an etched marking sits recessed or feels nearly flush, and a printed marking feels like nothing at all.
Side lighting confirms it. Tilt the cup toward a window and molded or etched graduations throw a shadow or shift the reflected light; painted lines read as a flat color layer sitting on top of the glass.
- Color is a clue, not proof. Bright red graduations are almost always a decorated system, not molded relief.
- Check the maker’s wording. Anchor Hocking describes its markings as screen decorated and fired on, while retailers may call the same cup “etched” or “raised.”
- Do not read permanence into “etched.” Confirm whether the source says molded, embossed, engraved, etched, fired on, or printed.
That last point matters most. Sellers use these words loosely, and the label on a product page is not a manufacturing spec.
Why Some Markings Fade and Others Don’t
Surface-applied paint and ink wear away because abrasion, detergent, heat, and utensils strip the coating; markings formed into the glass itself have no layer to lose.
| Marking Type | What Happens Over Time | Watch For |
|---|---|---|
| Molded or embossed | Ridge stays; contrast drops as grease and scale build up | Clouded glass, baked-on film |
| Etched or engraved | Recess holds up; can fill with detergent residue | Dull lines that need a vinegar soak |
| Fired-on decoration | Bonded to the glass; Anchor Hocking says it will not scratch off | Impact chips near the scale |
| Painted or screen-printed | Coating thins with scrubbing and dishwasher cycles | Patchy, ghosted numbers |
| Hard-water film | Marking is intact but hidden under mineral haze | White clouding across the whole cup |
| Scratched glass | Graduations still there but hard to read | Knife marks, rough patches |
A marking that looks gone is sometimes just buried. Grease, detergent film, hard-water deposits, and clouded glass all obscure a permanent graduation without removing it. Soak the cup in warm water with a splash of white vinegar, then wipe with a nylon pad before you decide the scale is dead.
Thermal shock is not a normal reason for printed color to disappear, but it can damage the glass around the graduations. If a line is genuinely illegible, the cup can no longer do its one job, and it’s time to replace it. Anyone weighing a replacement will find the tested shortlist at our glass measuring cup roundup useful for comparing which cups use fired-on versus molded scales.
Care Rules That Keep a Scale Readable
Wash with detergent and water using plastic or nylon non-scratch pads, and soak baked-on food instead of scraping at it, because sharp utensils scratch and weaken the glass.
Anchor Hocking rates its glass measuring cups oven, microwave, dishwasher, refrigerator, and freezer safe, and its care and use guidance adds the restrictions that protect both the cup and its markings:
- Center the cup in the microwave and keep it off the walls, since contact causes localized overheating.
- Never microwave an empty or nearly empty cup.
- Heat oils and fats only as long as the microwave maker recommends.
- Avoid sudden temperature swings — no liquid into a hot cup, no hot glass on a wet or cold surface, and always a dry cloth or potholder.
- Retire any cup that is chipped, cracked, or noticeably scratched.
Dishwasher-safe still isn’t chip-proof. Baskets let cups knock against metal and ceramic items, and those impacts are what shorten a measuring cup’s life.
What Should You Check Before Buying a Measuring Cup?
Read the manufacturer’s own description of the marking, not the retailer’s, and prefer a fired-on or molded scale over a printed one if you plan to dishwash daily.
Anchor Hocking’s measuring cup product pages spell out the marking type per model, and a current retailer listing is the honest place to confirm price and warranty — the 8-ounce 1-cup model carries a 5-year limited warranty, while a 1-cup version is listed as oven-safe to 425°F. Verify those figures against the listing you’re buying from, since they vary by model and change over time.
Common Questions
Can faded measurement lines be restored?
Sometimes, but only when the marking is intact and merely obscured. Soak the cup in warm water with white vinegar, then wipe with a nylon pad to lift hard-water film, detergent residue, and grease. If the glass itself is cloudy, scratched, or chipped around the graduations, the scale cannot be brought back and the cup should be replaced.
Is a red-marked measuring cup printed or permanent?
Red graduations are a decorated system rather than molded relief. Anchor Hocking states that its red markings are fired on and will not scratch off, which is a bonded finish rather than plain paint. Other brands may use ordinary printed color, so confirm the specific wording in the manufacturer’s own product description before assuming the same durability.
Does dishwasher use really wear off markings?
Repeated cycles accelerate wear in decorative coatings, and the main culprits are abrasion, detergent exposure, and contact with other cookware. Fading has been reported in some painted-marking products after extended use. A molded or etched scale has no coating to lose, so it survives the same cycles that thin a printed one.
