For registrars, conservators and exhibit designers: specifying vitrines and display cases, Museum Archival Finish, joint clarity, UV-filtering glazing, conservation-safe construction, mounts, cleaning.
Mount making is a conservation trade, and the mountmaker owns every object-contact decision. What a fabrication shop contributes is the other half: precision-cut, formed and polished acrylic components built exactly to the mountmaker’s drawings — easel backs, saddle cradles, ring mounts and rod assemblies, in ones or in families.
‘Airtight’ means three different things depending on who is asking — dust-resistant, sealed against air exchange, or watertight — and each one changes the construction. How to state the requirement as a test, choose the construction that serves it, and avoid the trade-off a tighter seal introduces.
Opening dates don’t move, so the casework schedule has to be built backward from one — through install, mount fitting, delivery, fabrication, and the approval step that is usually the longest single float. A worked back-planning template for exhibition teams.
Why institutions glaze works on paper with acrylic instead of glass — weight at large formats, shatter behavior around art and public — and the option ladder from standard clear through UV-filtering, abrasion-resistant, and low-reflection grades, with the honest trade-offs of each.
A vitrine’s bonded corner is where joint quality stops being abstract: viewed against gallery lighting, bubbles and haze either show or they don’t. How to specify joints by grade and sightline instead of asking for an \”invisible seam\” — and why that makes bids comparable and acceptance fast.
To a conservator, the case is part of the object’s environment — every material sealed inside it matters for years. How off-gassing thinking shapes bonded acrylic case construction, the sealed-vs-ventilated decision, and the disclosure protocol that makes a fabricator workable for a collections department.
The Oddy test is the materials screening a collections professional runs before approving a case vendor — and the reason blanket “tested safe” marketing claims mean nothing. What the test does, what its ratings mean for a build, and the fabricator protocol that actually works with it.
Registrars ask about dust and access before they ask about clarity — and the two questions are one design problem. The access decision that drives the sealing approach, the gasket and interface options as actually built, and why machining precision is the real sealing enabler.
Glass wins on surface hardness; acrylic wins on weight, break behavior, spans, and fabrication freedom. The comparison every exhibit designer runs, with the trade-offs conceded plainly instead of cheerled.
Somewhere past a certain size, a vitrine stops being a bigger version of a small one and becomes a different engineering problem — panels bow, sheet sizes run out, and the cover becomes a two-person lift. The design constraints to adjust for before quoting, not after.
