I have a mysterious roll of fine wire mesh that was given to me years ago by my brother. He died in 86'. I have recently retired and am now looking into this. He said it was valueable. While it looks like it might have some gold in it the whole roll looks like brass to me. I don't have a clue(?).

Can you give me a lead on a scientific company that produces such a kit and about what I should expect to have to pay for it?

Thanks.

Last year, I took both General Chemistry 1 and 2....I passed General Chem 1 but I don't feel like I learned ANYTHING but then in General Chem 2 I worked my butt off to get a B, but I don't remember much, especially the labs. Does Organic Chem really use alot of General Chemistry? Will I be in big trouble if I can't remember all the principles and stuff? I have to take both Organic Chem 1 and 2
