Frequently Asked Questions
What's the difference between Miron violet glass and regular amber or brown glass?
Miron's biophotonic violet glass is engineered to block the visible and UV wavelengths that break down cannabinoids and terpenes over time, while still letting violet and infrared light through. Standard amber or brown glass just cuts overall light transmission generally - it isn't tuned to a specific protective spectrum the way Miron's glass is.
How much product does the 5ml jar actually hold?
The 5ml capacity works out to roughly 2g of balm, wax or concentrate, depending on density. It's sized for personal-use portions or short-term working stock rather than bulk storage.
Is the lid safe for direct contact with concentrates?
Yes - the Ceres jar uses a glass screw lid (29 special thread), so there's no plastic liner sitting against your concentrate, unlike many standard glass jars with plastic-lined caps.
Do I still need to keep the jar out of direct sunlight?
We'd still recommend it. Violet glass significantly cuts the light wavelengths that degrade cannabinoids and terpenes, but it's a protective measure, not a substitute for sensible storage - keep jars in a cool, dark spot for the best shelf life.
Which pack size should I buy?
The Single jar is a good way to try the format. If you're processing or packaging concentrate regularly, the 10, 20 or 50-packs bring the per-unit cost down - the 50-pack is the best value per jar if you're going through them at volume.
Can the jar be washed and reused?
Glass jars can generally be washed and reused for the same or similar contents, but residue from concentrates can be stubborn - a warm isopropyl alcohol soak followed by a full rinse and dry is the usual approach. Let it dry completely before reuse to avoid trapping moisture.
Descripción
Miron Glass 5ml Ceres Jar is a violet biophotonic glass jar built for storing concentrates, waxes, balms and extracts in the dark – without actually needing to keep them in the dark. The near-black violet glass blocks the visible and UV light that degrades cannabinoids and terpenes, while still letting through the violet and infrared wavelengths the contents don't mind.
Holds roughly 2g of concentrate in a 5ml flat-profile, wide-mouth jar – small enough for a pocket, tough enough to actually protect what's inside.
Why Violet Glass, Not Just "Dark" Glass
- Biophotonic violet glass filters out the specific light wavelengths that break down cannabinoids, terpenes and other light-sensitive compounds
- Unlike standard amber or brown glass, Miron's violet formula is tuned to block the damaging spectrum while still transmitting violet and infrared light – the theory being this actively supports what's stored inside rather than just hiding it from light
- Reduces degradation from light exposure during storage, helping extracts hold onto potency and aroma for longer
Built for Concentrates, Balms & Extracts
- Wide-mouth, flat-profile design – easy to get a dab tool or spatula in and out without scraping the sides
- Glass screw lid (29 special thread) – no plastic liner sitting against your concentrate
- Genuinely airtight seal when closed properly, on top of the light protection
- Small enough to store loose or line up in a curing box alongside your other jars
Practical Details
This is the Ceres 5ml jar (Miron model HF10631-204) – the smallest in the Ceres cosmetic/concentrate jar range, with a 29mm special-thread glass lid. Buy it as a single jar to try, or step up to a multipack if you're processing in batches: 1, 5, 10, 20 or 50-pack options, all the same jar and lid.

Who Is This For?
The Ceres 5ml jar suits:
- Growers and processors storing concentrates, rosin, wax or extracted oils long-term
- Anyone curing or portioning balms and extractions who wants proper light protection, not just an opaque lid
- Buyers who want glass against their concentrate rather than plastic – no liner, no off-taste
Storing dried flower rather than concentrate? Our Grove Bags 1/8 Ounce Window range is built for that job, and a Boveda 62% Humidity Pack dropped into a curing jar keeps humidity steady alongside it. See the full range in our Trimming, Drying, Curing / Storage collection.
Why We Rate It
Most "UV-protective" jars on the market are just tinted plastic or brown glass – this is genuine biophotonic violet glass, made to a specific spectrum rather than just "dark enough." For anyone serious about concentrate quality after the work of extracting it, that's the difference between a jar that hides your product from light and one that's actually engineered around it.
