Abstract

In this work, it is reported that thermal analysis techniques such as differential thermal analysis and thermogravimetric analysis are very useful for evaluating metals threads and fibres used in the manufacture of historical artifacts. Thermal analysis has been used to characterize the silk, cotton and linen employed as supports and the copper, silver and aluminium as the metallic components in the studied threads. Other organic compounds, mainly added for the conservation of the threads, have also been characterized.

Keywords

Historical metal threads Metals (Ag, Cu, Al) Cellulosic (linen and cotton) and animal (silk) fibres Organic dyes and mordant Degradation TG–DTG–DTA

The samples were provided by two embroiderers, Fernando Enríquez Morán [http://brenesenlamemoria.blogspot.com.es/2014/10/bordados-fernandez-y-enriquez_5.html] and Eva Díaz Melero, and by Juan Antonio Conde and Antonio Albardonedo (private collections). Samples were collected to aid in the restoration processes of the artwork.
