I want to start my journey with refining gold and silver from jewelry using the inquartation method, and I know a fume hood is going to be probably my biggest expense, so I want to start here for safety equipment to gather, so a lil information before I ask for a recommendation, I only plan on melting and inquarting jewelry on a small scale as a hobby, maybe a few ounces of jewelry at a time, what kind of workspace or fumehood would this require? I'm thinking of working outside as opposed to inside because I rent my home and can't be cutting out holes into it for ducting, I am so lost and don't know where to begin... the process seems rather straight forward for the most part but figuring out anything about fume hoods seems to be a pain in the ass... im not very good when it comes to diy projects I don't trust myself to make safety equipment that's intended to protect my life or health, so I'd rather purchase a manufactured hood, something practical for my size of operation and that will keep me safe. Links or websites would be appreciated, links to a specific fume hood would be even more appreciated.
