Here is the piece I made last summer:
BEFORE I start, remember to consider safety. Ammonia is an harsh chemical; read the label and take precautions. Consider using a respirator as the fumes are HARSH and dangerous. The label on my ammonia container states: "MAY IRRITATE EYES AND SKIN. DO NOT MIX WITH BLEACH. DO NOT GET IN EYES OR ON SKIN OR CLOTHING. DO NOT BREATHE IN FUMES..."Here is what I did:
Then I took some wire and shaped it so that I could suspend the pieces in the jar so that they were not touching the ammonia and I hung the wire over the edges of the jar. I then covered the jar with a plastic wrap and left the container to sit. The article recommends allowing it to sit for 24 hours to 10 days).
And here is the original as a reference:
The pieces haven't achieved the colour I was hoping for so I have put them back in the jar for this week and will add a picture next week. Notice that the colour is not even, I am not sure whether this will correct over time, I guess we will have to wait and see.
