Safety & Care
We want you to enjoy the process and love the things you make. Here’s everything you need to know about working safely with your kit and keeping your finished pieces in great shape.
Safety
Non-Toxic Materials
nirii clay is non-toxic and has been independently tested
and certified to meet safety standards for art materials. It’s safe for adults
and for supervised use by children. No harsh chemicals, no fumes, no special
ventilation required.
Working Safely
- Wash your hands after use. The clay is safe to handle, but it’s good practice to wash up when you’re done, especially before eating or
touching your face. - Keep clay away from eyes and mouth. It’s not harmful, but it’s not meant to be eaten either. Keep it away from pets for the same reason.
- Sanding dust. When sanding dried pieces, fine dust is created. Work in
a ventilated area and consider wearing a simple dust mask if you’re sanding for
more than a few minutes. Wipe down your surface afterward. - Sealer safety. If you’re using a spray sealer, use it outdoors or in a
very well-ventilated space. Brush-on sealers can be used indoors with normal
ventilation.
Children
nirii kits are designed for adults, but older children can absolutely use them with supervision. We recommend ages 12 and up for independent use. For younger kids, an adult should handle the tools and help with any cutting or shaping. Keep small tool pieces away from very young children.
Caring for Your Finished Pieces
Everyday Use
Your finished, sealed pieces are made to be used, not just displayed. Set your keys in the catch-all tray. Put a candle in the holder. Enjoy them. They’re sturdier than they look.
Water Resistance
Sealed pieces are water-resistant, which means they can handle the occasional splash, a damp cloth wipe-down, or condensation from a glass nearby. They are not waterproof. Don’t submerge them in water, run them through the dishwasher, or leave them sitting in standing water.
Not Food Safe
This is important: nirii clay pieces are not food safe, even when sealed. Don’t use them as plates, bowls for eating from, or anything that will have prolonged direct contact with food. They’re perfect for holding jewelry, keys, candles, plants (with a liner), and decorative objects.
Cleaning
Wipe with a soft, damp cloth. That’s it. For painted and sealed pieces, avoid abrasive cleaners or scrubbing pads, which can wear down the sealant over time. If something sticky gets on a piece, a tiny bit of mild soap on a damp cloth will take care of it.
Handling and Durability
Air-dry clay is solid and durable for its intended use, but it’s not the same as kiln-fired ceramic. Treat your pieces the way you’d treat a nice candle or a ceramic mug. Don’t drop them on tile. Don’t stack heavy things on top of thin pieces. Common sense goes a long way.
Repairs
Accidents happen. If a piece chips or breaks, a strong craft adhesive like E6000 or Gorilla Glue works well for reattaching pieces. For small chips, you can fill with a clay-water paste, let it dry, sand smooth, and touch up with paint and sealer. Most repairs are barely noticeable.
Storing Your Pieces
If you’re packing pieces away or moving, wrap them individually in soft cloth or
tissue paper. Avoid stacking unsealed pieces directly on top of each other, as
they can scratch. Sealed pieces are more resistant to surface marks but still
benefit from a soft layer between them.
Storing Unused Clay
Seal unused clay in plastic wrap or an airtight zip-lock bag with the air pressed out. It’ll stay workable for several weeks. If it firms up, knead in a few drops of water. If clay has fully hardened in the bag,
it’s past the point of rehydrating. This usually only happens if it’s been left
unsealed for an extended period.
