Frequently asked questions

Miron glass is a unique violet glass that filters the full visible light spectrum while allowing specific UV and infrared frequencies to pass through. Miron is the only producer of this specific violet glass. This creates a more controlled light environment around the product inside, helping to slow the light-induced degradation of sensitive natural compounds. Unlike clear or amber glass, which allow varying amounts of visible light to reach the contents, Miron glass provides a higher level of light protection for sensitive formulations.

The violet color is an intrinsic property of the glass itself, not a coating or film applied to the surface. This means the light-filtering properties cannot wear off, chip, or be removed during cleaning or reuse.

Miron Violetglass specializes exclusively in the production and distribution of violet glass. We do have partners who work with other glass types. Please contact our sales team for guidance if you are looking for a different glass format.

Miron glass is produced in Europe under ISO-certified processes. All products are manufactured to consistent quality standards and are available from stock in EU and North American warehouses.

Flint (clear) glass offers no protection from visible light, allowing the full spectrum to reach the contents. Green glass filters a small portion of the light spectrum but still allows most visible light to pass through. Amber glass filters UV light more effectively but still allows a significant portion of the visible light spectrum to reach the contents. Miron glass filters the full visible light spectrum while allowing specific UV and infrared frequencies to pass, creating the most controlled light environment of these four options. This makes Miron glass better suited for products that are sensitive to the broader visible spectrum, not just UV light.

Yes. Miron offers a range of decoration options including silk screen printing, pad printing, hot stamping, and relief printing. These options allow you to apply your brand identity directly to the glass. A full overview of all decoration options and what is possible per format can be found on the dedicated Decoration page under Services on miron.com. For lead times and minimum order quantities, please contact our sales team.

Dimensions listed with a tolerance (indicated as a plus or minus value) are precise measurements. All other dimensions are approximate. For questions about specific dimensions relevant to labeling or filling line compatibility, please contact one of our sales representatives.

Anti-rotation nocks are small ridges on the bottle neck that prevent the closure from rotating once fitted. This ensures that pump heads, spray caps, and other directional closures always face the same direction after application. The result is consistent label alignment and a precise, considered presentation across every bottle in a product line. Anti-rotation nocks are available on selected Miron cosmetic bottle series, including the Capella and Virgo.

Glass production is energy intensive. However, its durability, inert nature, and recyclability allow it to maintain material integrity across multiple use cycles. Sustainability outcomes depend on application, reuse potential, and regional recycling systems.

Miron glass has been produced in Europe since 1995 and is engineered for durability and material stability. Its inert and resilient composition allows repeated use without degradation of the container itself. Its protective characteristics enable a packaging ecosystem in which longevity reinforces circular systems.

Yes. Glass is one of the most recyclable materials available and can be recycled indefinitely without loss of quality. Miron glass enters the standard glass recycling stream. One consideration is that the violet color may affect detectability by optical sorting machines in some recycling facilities. Miron is actively testing changes to the glass formula to improve detectability while maintaining its protective properties. For more information, have a look at our PPWR page.

Yes. Miron glass bottles and jars are designed with durability and reuse in mind. Many customers refill their Miron containers or repurpose them for storing other products at home, including spices, homemade preparations, and everyday dry goods. Reuse extends the useful life of each container and reduces reliance on single-use packaging. For more ways to reuse Miron glass, visit our Sustainability page.

Yes. All Miron glass products are produced in Europe under ISO-certified manufacturing processes. This ensures consistent quality standards across all products and production batches.

The PPWR (Packaging and Packaging Waste Regulation) is an EU regulation that aims to reduce the environmental impact of packaging across all materials. Its first key deadlines begin on August 12, 2026. The regulation focuses on reducing packaging waste, improving recyclability, increasing the use of recycled materials, and promoting reuse. As a glass producer, Miron is actively monitoring developments and supports the goals of the regulation. We will guide our customers through any relevant changes as the law comes into effect.
