Ok. So I was trying to make a diamagnetic clay for an experiment.
My thought was add copper oxide to bleached clay mix and kiln.
But once I mixed the copper oxide to the clay water solution now it keep making a film . It bubbles and smells like bad breath.
So I filtered alot of the clay before bleaching and then rinsed the the bleached clay before adding copper oxide.
The liquid seems to be more acidic then anticipated the spoon I used to skim the film is now pretty corroded. It's a cheap spoon I think nickel plated. But from what I have researched it doesn't make sense why it just keeps reacting. I skim and shake to no end it keeps making the light clay colored film every time any suggestions on what could be taking place.
