MAKING LAKE PIGMENT WITH MADDER: A HISTORICAL RECONSTRUCTION

The Making and Knowing Project, Columbia University
Last updated 2022-01-29 by NJR

Refer (insert something like “refer to the assignment sheet” instead of what’s here, keep jo kirby info though) also to Presentation: Cochineal Lake: History, Chemistry, and Preparation - while this is for a different colorant (cochineal), the chemistry of lakes is the same. (this was an experiment to try all three different recipes, each of which is listed below)

Jo Kirby et al, Natural Colorants for Dyeing and Lake Pigments: Practical Recipes and their Historical Sources (Archetype, London, 2014).

The recipes provided here are adapted from the ones provided by Kirby et. al.

Modernized recipes, adapted for the laboratory (or kitchen)

From the late 14th century to the 17th century, madder lakes seem to be most commonly extracted from madder-dyed wool and not the roots (raw dyestuffs). Recipes from before (antiquity) and after (18th and 19th centuries) tend to extract from the roots directly. Thus, the modern recipes adapted here are from this later period.

There are three modernized versions of the historical recipes:

  1. “Standard” - [Code: ML-Std in Natural Colorants]

    1. Extract madder in water, then add alum, precipitation of pigment with potash

  2. “Standard Reversed” - [Code: ML-EBAl in Natural Colorants]

    1. Extract madder in water, then add potash, precipitation of pigment with alum

    2. Color is said to be a very slightly redder, less brown than Standard

  3. “Standard with Alum Extraction” - [Code: ML-Std in Natural Colorants]

    1. Extraction of madder in alum, precipitation of pigment with potash

    2. Color is said to be a brighter red than Standard

An Alternative Method To Using Hotplates and Beakers

If you do not have access to hotplates and heat-safe glass beakers, an alternative method uses a water bath or bain-marie (see this cooking blog for more information about bain-maries).
