Conservation has a rule that surprises people new to it: the goal is not dry, it is stable. An over-dried bronze, an over-dried manuscript, and a damp one are all damaged — what harms an artefact is the wrong RH and the swing toward it. Different materials want different set points, and the system that holds them has to be powerless, non-corrosive, and reliable for months. That is what the Humidity Rubik's Cube is built for.
This guide covers museum and cultural humidity control with custom RH, and how the Humidity Rubik's Cube extends the Humidi-Cure fiber platform to any set point from 30% to 90%.
Why every artefact has its own RH
The right set point is dictated by the material. Ironwork wants very dry conditions near 15% RH to slow corrosion; non-ferrous metals and bronzes sit around 35%; ceramics, stones, jade, and fossils want 40–50%; calligraphy, painting, and works on paper want 50–60%; textiles want 30–50%; leather and fur want 40–60%. A single facility may need several different set points at once — which is why a one-size desiccant fails conservation.
What the Humidity Rubik's Cube delivers
The Humidity Rubik's Cube is the museum-grade extension of the Humidi-Cure fiber platform — the same non-ionic, non-leaking biodegradable fiber, customised to any RH set point between 30% and 90%. It holds the target at ±3% precision at room temperature (20–25°C), and provides 1.8 to 2 times the moisture capacity of silica-gel humectant benchmarks across RH 30–60%. Critically, it is powerless — no electricity, no maintenance, and none of the startup/shutdown disturbance that mechanical systems impose on a sensitive microclimate.
Why non-ionic matters around irreplaceable objects
The single most important property for collections is that the medium cannot harm what it protects. Salt- and liquid-based humidity products risk leaking ions that corrode metals and stain artefacts over time. The Cube's fiber contains no liquid and no volatile ions, so it sits safely beside bronzes, ironwork, paper, textiles, and fine wood. This is the same reason ATMOSIScience's platform is trusted at institutions including the Shanghai Museum.
Where it is used
Sealed display cases and vitrines that must hold a set RH for months; transport crates for loans and acquisitions crossing climate zones; archival storage cabinets and boxes for paper, photographs, and textiles; and microclimate framing for works on paper and panel paintings. Each deployment is sized to the enclosed volume and the material's target RH.
How to order — this is a B2B product
The Humidity Rubik's Cube is configured per institution and is currently available only through B2B partnerships or wholesale — the setup differs from the retail Humidi-Cure packs because the RH set point, format, and capacity are customised to the collection. To specify a Cube, share your material types, enclosure volumes, and target RH levels, and the team will return a configuration and quote.
Frequently asked questions
What RH should museum artefacts be kept at?
It depends on the material: ironwork ~15%, non-ferrous metal ~35%, ceramics 40–50%, paper/painting 50–60%, textiles 30–50%, leather 40–60%. The Cube is set to match.
How is the Cube different from a retail Humidi-Cure pack?
Same fiber platform, but customised to any RH from 30–90% with museum-grade capacity, ordered via B2B rather than off the shelf.
Is it safe around metal and paper artefacts?
Yes — non-ionic and non-leaking, with no liquid or volatile ions to corrode or stain. Trusted by institutions such as the Shanghai Museum.
Does it need power?
No. It is powerless — no electricity, no maintenance, no mechanical disturbance to the microclimate.
