Borosilicate Glass Containers

Originally, Pyrex was made entirely from borosilicate glass, known for its low thermal-expansion coefficient. Today, some Pyrex products (particularly in North America) use tempered soda-lime glass instead. True borosilicate glass, like the type Gemixx uses, retains superior thermal-shock resistance compared to soda-lime alternatives.

Borosilicate glass contains boron trioxide, giving it a lower thermal-expansion coefficient and higher resistance to thermal shock than soda-lime glass. This makes borosilicate better suited for containers exposed to rapid temperature changes, such as hot liquid fills, while soda-lime glass is typically used for decorative or ambient-temperature applications.

Borosilicate glass generally withstands higher temperatures and rapid temperature swings better than standard soda-lime glass, making it suitable for many hot-fill and heat-exposure applications. However, oven and microwave suitability depends on the specific product design and wall thickness, so it's best to confirm intended use cases with Gemixx during the quoting process.

Gemixx manufactures a wide range of borosilicate glass items, including candle vessels, jars, hurricanes, tumblers, decanters, and double-wall insulated drinkware like French press carafes and mugs. These are produced through hand-blown and pressed manufacturing methods and can be customized with clear, colored, frosted, or cut finishes.

Yes, Gemixx offers full private label development for borosilicate glass containers, including custom molds built from a sketch, render, or competitor sample, plus embossing, etching, and printing to client artwork. This allows brands to create fully differentiated, exclusively branded glass container lines.

MOQs vary depending on whether an existing mold is used or a new custom mold is developed, along with the finish and overall order volume. Gemixx provides MOQ and pricing details within a formal quote, typically delivered within 48 hours of inquiry, and supports scaling from capsule collections to high-volume programs.
