7. The Coloniality of Materiality: Brazilwood, or Unlearning with Anton de Kom in the Mauritshuis

open access: yes, 2023
In this article, Oscar Ekkelboom provides a critique of "materials" as a concept that is predicated on an extractivist practice that reinforces the logic of coloniality. Building on Anton de Kom's consideration of the wooden interior paneling of The Hague's Mauritshuis, Ekkelboom's decolonial approach opens up thinking about the afterlives of things in

EXTRACTION OF ECO FRIENDLY NATURAL DYES FEOM BRAZILWOOD AND THEIR APPLICATION ON FABRIC

2023
The art of dyeing is a complex and specialized science, with most dye stuffs now being produced from synthetic compounds. Synthetic dyes have significantly reduced costs and enhanced certain application and wear characteristics. However, proponents of natural dyeing, which involves using dyes sourced from naturally occurring materials such as plants ...

A proof-of-concept study: Determining the geographical origin of Brazilwood, (Paubrasilia echinata) with the use of strontium isotopic fingerprinting

Science and Justice - Journal of the Forensic Science Society
The illicit exploitation of Brazilwood (Paubrasilia echinata) presents a significant challenge in Brazil, given its substantial value in the global production of bows for musical instruments. To address timber provenance, the use of strontium (Sr) isotope ratios as indicators of bedrock signatures has emerged as a robust tool in forensic investigations.

A Study of Certain Natural Dyes I‐The Adsorption of Brazilwood and Logwood Colouring Matters by Fibres

Journal of the Society of Dyers and Colourists, 1954
The adsorption properties of hæmatein, the colouring matter from logwood, and its leueo compound, haEmatoxylin, together with brazilein, the colouring matter from brazilwood, have been studied on several types of fibre. Brazilein and haEmatein are weak acids and are adsorbed by wool or nylon appreciably only from acid solutions, probably by hydrogen ...

A Study of Certain Natural Dyes II‐The Structure of the Metallic Lakes of the Brazilwood and Logwood Colouring Matters

Journal of the Society of Dyers and Colourists, 1954
The lake‐forming reactions of the oxidised and reduced forms of the logwood and brazilwood colouring matters with the more important mordanting metals have been investigated. The oxidised forms appear to be the lake‐forming species, the o‐hydroxyquinone system of the molecule chelating with the mordanting metal atom; the leuco forms must first be ...
