Free online calculators for the natural dyer and ecoprinter

Studio calculations are the unglamorous part of the practice. Getting them wrong wastes materials, produces inconsistent results, and makes it harder to understand what actually happened in the dye bath.

These tools are built to make the arithmetic disappear so you can focus on the making. Enter your fibre weight and the calculator does the rest — scaling recipes to your specific batch, whatever the size.

The current tool is the homemade alum acetate mordant calculator, scaled to the Boutrup and Ellis recipe with both the baking soda and washing soda methods. More tools coming as the resource library grows.
