Corelle’s signature Vitrelle glass plates and bowls are made in Corning, New York.
Mugs and some stoneware pieces sold alongside those plates are typically imported, largely from China.
So a single Corelle set can genuinely be part American made and part imported.
Ownership of the Corelle brand has also changed hands twice in the last few years.
That happened following a bankruptcy of its former parent company.
This article covers what is actually made in Corning, what is imported, who owns Corelle today, and how a sister brand’s factory closure fits into the picture.
So let’s get started.

Where Is Corelle Dinnerware Made?
Corelle sells its dinnerware through its official site corelle.com.
The physical manufacturing behind the flagship Vitrelle line happens at a plant in Corning, New York.
That plant produces the tempered glass plates and bowls Corelle is known for.
Collections like Livingware, Lifestyles, Impressions, and Corelle Square all rely on plates and bowls produced there.
Mugs and some stoneware or accent pieces are manufactured overseas, primarily in China.
Is Corelle Made in the USA?
The core plates and bowls in Corelle’s mainline Vitrelle collections are made in Corning, New York.
The mugs bundled into many of the same sets are not made domestically.
So a boxed set can genuinely include both American made plates and imported mugs under the same label.
Who Owns Corelle?
Instant Brands, the parent company that had merged Corelle with Instant Pot and other kitchenware brands under private equity firm Cornell Capital, filed for bankruptcy in June 2023.
The restructuring plan was approved in February 2024.
The housewares division emerged under a new name, Corelle Brands, initially owned by prior lenders including Centre Lane Partners.
Centre Lane then folded Corelle Brands under its other holding, Anchor Hocking, per Wikipedia.
Where Did Corelle Come From?
Corelle built its reputation on Vitrelle, a laminated tempered glass developed for lightweight, chip resistant dinnerware.
That process has anchored production at the Corning, New York facility for decades.
The brand’s core identity has always been tied to that specific plant and its glass technology.
Ownership around the brand has shifted, but the manufacturing process itself has not moved.
Why the Pyrex Factory Closure Matters for Corelle
In 2024, Anchor Hocking announced it would close a 132 year old glass factory in Charleroi, Pennsylvania, that had been producing Pyrex.
Production shifted to Lancaster, Ohio.
Pyrex and Corelle are sister brands under the same corporate ownership, so the Charleroi closure did not shut down Corelle’s own Corning plant.
Pyrex and Corelle are both owned through the same corporate family today, while their manufacturing locations remain separate.
Corelle vs Pyrex: Who Makes Each?
Corelle’s core plates and bowls continue to come from Corning, New York.
Pyrex production has consolidated toward Lancaster, Ohio following the Charleroi closure.
Both brands sit under the same ownership umbrella but run through different factories.
What Is Next for Corelle?
Corelle’s Corning, New York plant continues to produce the brand’s core Vitrelle plates and bowls.
Its ownership sits with Corelle Brands under Anchor Hocking, controlled by Centre Lane Partners.
How that ownership group treats its glass manufacturing plants going forward remains an open question for shoppers who care about domestic production.

Frequently Asked Questions About Where Corelle Dinnerware Is Made
Are all Corelle products made in the USA?
No. Corelle’s core Vitrelle glass plates and bowls are made at Corning, New York.
Mugs and stoneware pieces sold in the same sets are typically imported, mainly from China.
Who owns Corelle in 2026?
Corelle is owned through Corelle Brands under Anchor Hocking, controlled by Centre Lane Partners.
This followed the 2023 Instant Brands bankruptcy and the 2024 restructuring that separated Corelle from its former parent.
Why did the Pyrex factory closure raise concerns about Corelle?
Pyrex and Corelle share the same corporate parent.
So when the Charleroi, Pennsylvania Pyrex plant closed in 2024, it raised concerns about how the new ownership treats legacy American glass manufacturing, even though Corelle’s Corning plant was not affected.
Is Corelle glass or ceramic?
Corelle dinnerware is made from Vitrelle, a laminated tempered glass, not ceramic.
That glass process is why Corelle plates are lighter and more chip resistant than traditional ceramic dinnerware.
