Don't pour silver directly into the wax. It will blow up! I worked with a guy that couldn't smell very well. He poured aluminium into a wet mold and it blew molten metal up his nose.

Here is the best video that I found of what what you can do at home. He has a few more toys than necessary but it gives you a good idea of what is needed. The vacuum table that he uses for his investment is also good for pouring larger molds.
