I used pure white vinegar becasue i want to use it as an oxide wash for pottery.
Adding salt will help.
Quenching in water will cool the wire rapidly and cause the scale to pop off. Quenching does not affect the malleability of the wire.
The photo in my reply above is before and after 1050F for 4 hours.
Here is a photo after a few days in plain white vinegar
I’m curious about using this as an oxide wash for ceramics, do you do anything with the vinegar/oxide/salt mixture before using it as a wash?
Disclaimer: I have only taken one 7 week hand building ceramics class.
I watched a video with someone experimenting with dissolving steel wool in vinegar for an oxide wash. I work as an industrial heat treater so i have access to scale of different types of steels. I plan on taking another class and experimenting with different materials & techniques. My instructor was also intrigued and allowed me to experiment. I’ll add a pick of the results of my first experiment this weekend. It was from a stainless not from the copper.
I only used white vinegar and let it dissolve the stainless as much as possible maybe a few days. It was watery and a translucent. My “copper bucket” has had the slag for weeks and is evaporating. I’m interested to see what happens with the coloration. Classes just started again, but I’m not registered for this session.
