Manufacturing practice- Materials

To be able to manufacture environmentally sustainable jewellery, I need to ensure my practice is sustainable. This means working eco-consciously with awareness of the negative impact my practice may have on the environment. Creating ‘sustainable’ jewellery will therefore involve primarily identifying my practice which is broken into -Materials,- Processes/Methods and -Techniques. From there I am able to adjust my practice (where need be) to implement minimal or no environmental harm.

-Materials

 “The most important characteristic of green jewellery today is ethical material sourcing, and all sourcing issues stem from one central issue: extraction.” Craig (2009 : Pg 34).

 I mainly use silver for manufacture, other materials I may sometimes include in my work are enamels and ceramics.

A. Silver

  There are two ways in which to source silver, Through either Primary or secondary refining.

-          Primary refining

            This process is whereby first time silver is extracted from the earth (this can be environmentally devastating).  

-           Secondary refining

             The silver is sourced from an already existing product (recycling, or re-melting old silver jewellery).This process uses less resources, chemicals, and energy. One-fifth of silver mined each year, worldwide, goes into X-ray film. Craig (2009 : Pg36).

I am currently buying my silver from a secondary refiner (Virgo Metals Durban- 031 207 4290). This silver has been extracted from old X-rays. 

B. Enamel

 Enamelling is a technique that was used by most of the ancient civilizations and was continued to be used throughout history and still today. Enamel is basically ground glass. It is made from an extremely friable type of glass called frit. It is coloured using various minerals or metal oxides.- I don't see any sustainable related issues to enamel itself. Although different firing methods can be more or less sustainable (that will be touched on in my techniques section).

C.Ceramics

There are many different types of clay. I will have to find out from my supplier (Kamel Kilns) a bit more about the clay's and their origins before i can comment or judge.  

 Clay can also be primarily or secondarily sourced.
-Primary clay is found at the source where it formed. In some cases areas are deforested in order for its extraction :(.
-Secondary clay is where deposits have been moved from the original  location by erosion or water.


(Different firing methods will be looked at in the techniques section as well).
