I changed my avatar, the ghostbuster avatar was supposed to be temporary after I got rid of my custom swastika avatar (a classic!), which I considered bringing back.
But while I was looking at the prices of copper I came across old alchemy symbols for precious metals. The above being the symbol for copper.
I was going to use a picture of coiled copper, but I doubted most people would be able to tell what it is, anyway. Not that they'd know that the above is the symbol for copper, and if anything could confuse it for the symbol for women.
We'll see how it goes.
And for those that are wondering why my interest in copper?
I'm an electrician's apprentice and as such I work with copper wire which is one of the world's best/affordable conductors for electricity. I also collect copper scrap to take to the local scrap yard where I've been getting 2.50 per pound.
I've gotten a total of 260 dollars so far and I still have more to strip.
