← Back to What to harden resin?


Mineral resin has become a favourite among crafters and artists thanks to its versatility, safety and eco-friendly qualities. If you’re considering new ideas for decorative casting or want a safer resin solution, mineral resin offers a great alternative.
Best Uses for Mineral Resin
This resin is especially popular in projects that include coasters, trays, flower pots and a wide variety of decorative items. Its ability to harden to a ceramic-like finish makes it an excellent choice for both indoor and outdoor objects. After curing, mineral resin pieces can be painted or customised, opening up endless options for personalisation. For example, crafters commonly use NatuResin – Mineral Resin & Water System for unique small-batch castings and even practical outdoor pieces like garden planters.


User Safety and Handling
Safety is a standout benefit of mineral resin. It is solvent-free, VOC-free and does not require gloves during normal use, making it suitable for classrooms and home studios alike. Its water-activated formula means you avoid harsh chemicals, and there is minimal odour. However, as with any crafting material, a tidy workspace and basic hand hygiene are always recommended.
Practical Guidance for Beginners
- Mix the resin with tap water according to instructions – there’s no need for additional hardeners or catalysts.
- Pour into moulds for making coasters, trays or decorative accents.
- Let the piece cure thoroughly before demoulding and decorating further.
- Once cured, the result is robust enough to display outdoors, with a weather-resistant, hard surface.

When Does Mineral Resin Matter Most?
