You’ve found your favourite clays, placed your order, and now that satisfying box has landed on your doorstep. You open it, breathe in that earthy aroma, maybe sneak a quick crunch... and then the big question hits: how do you store them properly so they stay perfect?
The truth is, raw and roasted clays are sensitive little things. A touch of moisture, a bit of heat, or too much air exposure can turn that lovely crisp snap into a soft crumble. Luckily, keeping your stash in peak condition isn’t complicated – it just takes a little know-how (and the right containers).
Here’s how to safely store your edible clays, chalks and treats at home – and make sure every crunch stays as good as the first.
1. Keep it airtight
Moisture is the number one enemy of edible clays. Once air gets in, the crisp texture starts to fade. Always use airtight containers to lock out humidity and keep that signature crunch intact.
This is where aluminium tins come into their own. They’re sturdy, sleek, and keep out both moisture and light. They’re also fully reusable, eco-friendly and easy to label if you’re building a stash. The tight seal means no sneaky dampness creeping in and no lost flavour over time.
2. Separate your stash
If you’ve got a few different clays on the go, make sure you store each one separately. A smoky roasted clay and a delicate chalk don’t play nicely when kept together – the stronger aromas can easily take over.
That’s why clear compartmented boxes are such a win. You can store multiple clays in one tidy, see-through organiser without the flavours mingling. It’s perfect for stash builders who like to see everything at a glance – and far more satisfying than juggling little packets.
3. Cool, dark and dry is the magic trio
Just like fine tea or chocolate, clays prefer a stable environment. Keep them somewhere cool, dark and dry – think cupboards, drawers or shelves away from direct sunlight and steam.
Avoid storing clays near radiators, cookers or windows, as heat and humidity can make them lose their crisp edge. If your home tends to get humid, you can pop a small silica sachet near your storage tins to help absorb extra moisture (just don’t let it touch the clay directly).
4. Hands off (mostly)
It’s tempting to handle your clays often – to admire, sniff or just test that crunch. But oils and moisture from your fingers can transfer to the surface, dulling both flavour and texture.
That’s why every Earthy Crunch UK order comes with a little wooden spoon – it’s not just for unboxing aesthetics. It helps you portion your clay neatly, keeps everything hygienic, and stops those natural oils from sneaking in.
5. Short-term vs long-term storage
-
Short-term: if you plan to enjoy your clays within a week or two, airtight tins are perfect. They’re easy to open, reseal and stack.
-
Long-term: if you’re saving different types for later or like to rotate your stash, the clear compartmented boxes are ideal. They keep everything separate, dry and visible – no forgotten pieces hiding at the back.
6. No plastic baggies, ever
At Earthy Crunch UK, we don’t do plastic baggies. Not only are they terrible for the environment, but no one needs microplastics leeching into their clays or affecting the taste. Each and every one of our items comes in its own separate container – designed for freshness, hygiene and sustainability.
Before packing, all of our clays, chalks and roasted treats are carefully aired out to remove any natural dampness. This ensures they arrive crisp, clean and ready to enjoy straight from the box.
7. Avoid the fridge
It might seem like the fridge would keep clays fresher for longer, but it actually does the opposite. The cool air creates condensation, which softens the surface and destroys that signature crunch. Room temperature storage is always best – as long as it’s away from humidity.
8. Make storage part of the fun
There’s something oddly satisfying about organising your collection. Lining up tins, sorting different clays into compartments, or labelling your favourites can become part of your ritual. Think of it as a mindful moment before the crunch – a little calm before the clay storm.
The takeaway
Good storage is the secret to keeping your clays fresh, crisp and flavourful. Airtight tins for short-term freshness, compartment boxes for long-term stash organisation, and a cool, dry spot to keep them safe.
At Earthy Crunch UK, we make it easy to do things right – no plastic baggies, no hidden microplastics, and no soggy surprises. Just clean, crisp, beautifully packed clays that stay crunchy from our hands to yours.
Because when it comes to clay, it’s always crunch time.
