Tempered glass measuring cups for hot liquids — the one measuring job where a plastic jug is genuinely the wrong tool, because heat and plastic is exactly the combination to avoid.

Why it's safe for your family

Glass is inert against boiling liquid. A plastic measuring jug filled with just-boiled water is a small daily version of the exposure this whole site is about, and this is the cheapest possible swap out of it.
The measurement markings are fired onto glass rather than printed on plastic, so they survive the dishwasher instead of fading into an unreadable jug after two years.
Anchor Hocking states its glassware is made in the USA, in Lancaster, Ohio — one of the few remaining domestic glass manufacturers, and a fact we verified against the company’s own site before printing it.
Tempered glass tolerates the thermal shock of hot liquid going into a room-temperature cup, which ordinary glass does not reliably do.

What to avoid instead

Avoid measuring hot liquids in a plastic jug, and avoid the melamine and plastic nesting cups sold for baking sets. For dry ingredients plastic is a much smaller issue; it is heat and fat that move things out of plastic and into food, which is why the liquid measure is the one to change first.

How we verify — and what we don't

Straight answer: we're a research team, not a testing lab. Here's exactly what our rating is based on — and what it isn't — so you can weigh it honestly.

What we check

What the product is made of, from the maker's own specs and product listing.
Whether any part that touches you or your food uses PTFE, PFAS, plastic, or a coating that can degrade.
Peer-reviewed research on how that material behaves when heated, scratched, washed, or worn.
Known failure modes — how the product actually breaks down in a real home.

What we don't do

We have not chemically tested this specific unit in a lab.
We don't take payment to rate a product higher — there is no sponsored placement.
We don't show star ratings or "trusted by thousands" counts we can't stand behind.

What gets a product rejected

Anything that adds a known microplastic, PFAS, or off-gassing source — a non-stick coating, a plastic surface against food or skin, vinyl/PVC — is downgraded or cut. We only list what clears that bar.

Common questions

Will it crack if I pour boiling water in?

Tempered glass is made for this, with one caveat that applies to all glass: avoid extreme swings. Do not pour boiling liquid into a cup straight from the freezer, and do not set a hot cup on a cold wet counter. Room temperature to boiling is exactly what it is designed for.

Do the markings wear off?

They are fired onto the glass rather than printed on top, which is the difference between a cup you can still read in five years and one you replace. It is also the practical argument for glass over plastic here, separate from anything about chemistry.

Is it really made in the USA?

Anchor Hocking states its glass is manufactured in Lancaster, Ohio. We record the source and the date behind claims like that rather than repeating them from a listing, because "American brand" and "made in America" are not the same sentence.
