Clarity, and the gap

On this page10
Under a third. Better than the coins shelf and still a gap worth naming.

The archetype's position

"Displayed as much as stored. Clarity matters more than anything else." For a collection of sea glass that is exactly right.

What the shelf actually offers

94 clear containers out of 298. By colour the rest is 59 white, 45 amber, 29 blue and 26 natural, which is a lot of opaque for a display craft.

Which is the same gap the coins property found

And it is worth stating the same way: if visible storage is the point, the real choice is 94 containers rather than 298, and that is still a usable range.

Glass improves the clear end

Of the clear containers, the glass ones are the better long-term object. PET is clear when new and can scratch and haze with handling, which over decades shows.

Amber has a real use here

45 containers. For a find that fades, amber is the compromise between seeing something is there and protecting it, which suits a working collection better than either extreme.

Opaque suits the archive half

Most collections have material that is kept rather than shown. White and natural containers with a good label are the right home for it and cost nothing in enjoyment.

So split the collection, not the container choice

Display in clear glass, archive in opaque, and let the label do the identification in both. That is a system rather than a compromise.

A clear jar is also a label

Being able to see the contents means the container identifies itself, which for a collection consulted often saves opening it and saves the label from being the only record.

And PET scratches where glass does not

For a collection that will be handled for decades, the 63 glass Boston rounds and 21 glass straight sided jars are the better long-term clear container, at the cost of weight and breakage.

Whether a particular find may lawfully be collected or kept depends on the species, the land it was found on and the state; this property names the questions rather than answering them for a specific object, and a valuable or unusual find deserves a better source than a packaging catalog.
