Calcium Carbonate – Chalk for Dunging & Textile Work
We are pleased to offer two high-quality sources of calcium carbonate, both perfect for dunging printed, dyed, or mordanted fibres:
-
Chalk from Blanc de Meudon (France) – A traditional, fine-textured chalk often used in textile work.
-
Local Limestone Chalk (Co. Clare, Ireland) – Sourced from our nearby quarry in the Burren, an iconic Irish limestone landscape just a short drive from our studio.
Our local limestone is rich in calcium carbonate and performs beautifully for dunging. As we collect it in its natural state, you may notice tiny stones or mineral impurities. If desired, simply sieve the chalk before use.
⚠ Please note: This product is not fit for consumption. Also, all our products are packed in resealable paper bags.
How It Works
Calcium carbonate is a key ingredient in traditional fabric treatment. It acts as a substitute for cow dung, which was historically used in the “dunging” process. By using chalk, you achieve the same result in a clean and environmentally friendly way.
✨ Suggested Use:
-
Add 1–2 tsp, or approx. 1% of the dry fabric weight, to water or 1-3g/L
-
Stir well to create a dunging solution
-
Use to treat fabrics after dyeing or printing
Both options work equally well, allowing you to choose between the historic Blanc de Meudon chalk or our beautiful locally sourced limestone from the Burren.
