Just wondering if anyone ran into to these type of tracings on ceramic chips.
The gold tracings won't come off in AP but after several days/week the ceramic lid eventually comes off the white ceramic. You can't see it but there are small gold wire leads on the fine finger end of the white ceramic and also at the 7pc's of embedded silicon chips.
The leads attach to a dark pretty much black trace, those black traces eventually lift but the AP and or HCl and HCl clorox does not effect the black leads.
Its kind of an interesting chip.
What type material do you suppose the black lead is?

I have only done the AP and Sulphuric methods thus far. However I did manage to pick up 4LB's of Sodium Nitrate to learn about making Nitric from it.
I assume if I can't take it into solution I can't test it.
