I have designed a pendant for a friend and now for the first time
since college I have a need to chemically blacken the resesses of a
silver item.
I don’t remember what we used to use at college for this process -
just that it was a liquid solution kept in an airtight and darkened
bottle. I do remember that it smelt like rotten eggs.
The catalogue for my local jewellers supply store listed “Jax Silver
Blackener” and “liver of sulphur” for these purposes. I phoned the
store and they don’t currently have any Jax Silver Blackener in stock
and they don’t sell liver of sulphur anymore. After finding this out
I started pawing through my books and found quite a few listings of
different solutions that can be used on different metals to acheive
particular colours. Most of the solutions had chemicals as
components that I have never heard of before and probably couldn’t
purchase. I noticed that several of them had vinegar, salt or
ammonia as components…
I ended up finding a listing of “bleach” for creating a grey colour
on silver. Given that I had nothing else I could work with until
the new stock of Jax Silver Blackener comes in I thought I’d put
some test pieces into bleach and see just what happened. The colour
I found got darker the longer I left it and for my purposes (just
wanting to darken the resesses) it will do the job fine.
I was surprised to find such a simple solution to my problem and
wanted to post about it for two reasons:
-
In case others aren’t aware of this one and it may be useful to
them -
To ask if anyone out there in orchid land knows of any other
solutions for colouring metal that can be made up using household
products/items that you can purchase from your local supermarket.
Thanks,
