    One thing, or actually several, you need to invest in: compressed
    charcoal blocks. These are made with the brand name of PANA, from
    Germany. The only drawback with them is that you can't just push in
    jigs and tables (have to drill a hole first). But, they really hold up
    well for students. I've been using one for about 2 years now for my
    regular soldering. It's about 1/2 the height it used to be, from me
    sanding it down occasionally to get a level surface, but they don't
    break up like regular ones. I use another for my granulation. I've
    probably done around a 1,000 granules, give or take a couple hundred,
    with very little degradation. You can't say that about a regular
    charcoal block. 

Usual disclaimer here.
