Manufacturing Practice- Techniques

This list includes the techniques I use to create a desired effect on my metal (this has a relatively small scale negative impact) but some of these may need either alternate methods to ones generally used or have to be cut out completely.

     A.  Piercing- Includes saw frame and saw blades

B.Enameling- Glass enamel, glue, which is organic based gum and a kiln. The problem with kilns is they draw a heck load of electricity. 
      Alternative- Torch firing enamels, this just means there is less room for the various techniques of                      enameling. and that the backs of the pieces will burn slightly- adds to the effect i guess.

 C.Etching- To etch silver nitric acid is used.YUK. big NO NO. So i oust that completely.  
       Alternative- Find out if there is an eco alternative to get a similar effect. 

D.Chasing and Repousse- I make my own Chasing punches out of old tool steel, using old allen keys. Im not sure if using pitch is a problem or if i need to find alternatives. Ive worked on pine scraps, but detail is a problem as the plate needs to be held still. 

 E. Fly pressing- Uses a 20 ton hydrolic jack- second hand ones are easily available.

F.Casting- common lost wax casting technique for the entire process can include the necessity for , A valconizer, silicone, Pattern wax (aka injection wax), flasks, investment(terrible stuff), a de-bubblizer/casting machine and a kiln. 
     Alternative- Sand casting, or cuttle fish casting

G. Blackening- Liver of sulphur (also terrible stuff).
       Alternative- Boiled egg, re usable airtight container. 

      Im looking for other sustainable techniques that can create detail.Not really sure how to go about this just yet. I think a good place to start would be to look into primitive and ancient techniques and tools. By default they mostly made jewellery in a "sustainable" way because they had fewer resources and no mass production abilities. I would also have to look into cutting out certain techniques, like ones that include the use of toxic chemicals, and other un-essential, negative impact methods.

Egg- The Eco friendly alternative to Liver of Sulphur

So never been quite so excited about egg (other than when I've had a few too many glasses of wine the night before :)). I came across a site called ''Finishings dot com''... and through a conversations thread by jewellers found this out-
The trick here is easy peasy, hard boil an egg, break the shell and squash it a little. Then leave it for a day in an air tight container with the piece of jewellery. If the piece has not been polished it blackens in a couple of hours, if its polished it take a little longer. The areas you don't want blackened cover with tape, i used masking tape but with the moisture from the egg it just peeled off. The solder joints stayed white, but will see with my next test. This is how my test pieces turned out ;) Now to use it on actual jewellery.

the back 1 is fine silver and the front one is 925.
