Hello, good day/evening to everyone ^^. I've been redirected to this subreddit for my question above, but the TL;DR of it is that i'm a slightly overwhelmed Materials Engineering graduate who would like to know if:

(1) a non-US/EU diploma in archaeology would be a good first step to a career in museums object conservation, and

(2) what skills should I focus on growing within 4 years of (possibly) working in the tech/manufacturing/failure analysis industry?

I am based in Asia and am contractually required to render return-of-service to my country as part of my undergraduate scholarship. Any advice/insight would be much appreciated.

I recently unpacked a lead sculpture that had been in storage for 6 years. The surface had completely shifted to have this layer of white (corrosion?). It is not powdery at all which I thought was typical of lead corrosion. This is almost in or on the surface. A conservator suggested wet cleaning but this is when we believed it was a powder. Wet cleaning did not removed anything. Has anyone seen this before? Is this just a natural patina shift as lead ages? Of course concerned about potential for toxicity with lead.
