    Pitch can be from very hard to very soft and this can be controlled.
    The hardness used will depend on the type of work you are doing. I
    have used several different pitch types over the years and found
    Allcraft in New York to have the best and most consistent. The two
    primary I am familiar with are black and red. Allcraft can advise
    you on which is best for your needs. 

    The hardness can be adjusted by adding oil (I use olive oil for the
    high flash point) to soften or powder to firm. Many different
    powders work and I use talc. You will need to experiment with the
    powders, as too much can have an adverse effect on the pitch. When
    doing fine detail you could try a trick I've used. I like to have a
    very soft pitch, but the piece moves too much in the bowl. After
    placing the piece in the pitch, freeze the whole bowl. The pitch
    under the work area will soften immediately for the fine work, but
    the rest will remain hard for a while to support the work. Refreeze
    as necessary. 

Hope this helps,
dan
