One question about alternative tecnique


#1

hI I am a jewelry designer and work with non-precious metals such as
german silver or an alloy of bronze (more soft bronze) I ask you my
question, I hope you can help me. It seems to me have seen on your
website, the book by Carles Codina Color Texture & Casting For
Jewelers.

So I decided to make two pastas: Granulation Paste on page 38 Copper
and Paste on page 59.

Can you tell me as I have tried to make these pastes but do not
work, especially the second one.

I would understand if they do not work because I’m working with
other types of metal or something I did wrong in the production of
pasta? I hope you can help me. I contacted the publisher and the
artist but still have not received a reply, I am worried I would go
ahead with it take to get my experimental work.

Thank you very much, and a good work!

the nickel alloy should work with copper pastes: They are intended
to fuse copper to a copper containing alloy- nickel silver contains
60% copper,20 nickel and 20% zinc most commonly-The pates simply
provide enough “glue” to hold granles in place. Be certain the grain
are clean and grease free, there is no charcoal or carbon to 'block’
any part of the surface fro contact with the base you are attaching
them to and provide some channel or cribed pattern to help the grain
stay in place-gum tragacanth and used pickle work very well-the
deeper the blue colour the higher the copper content so when heated
the granules flash into place a thugh you were electroplating them
with a thin coating of metal… double check your proportions in
recipes and the cleanliness of both your grains and subtrates. If you
have further questions feel free to contact me off ilis rer

Maria - I/we would like to help, but the translation of pasta or
paste isn’t clear.

Is paste the word in your language for flux - a solution to permit
soldering or granulation?
