Yes, you need multiple plates to do multiple colors. Litho doesn't work as
a resist, the drawing medium on the stone attracts and holds the ink.
Be aware that many traditional printmaking techniques use toxic chemicals.
There is a movement in printmaking towards safer chemicals. In litho, there
is a new product called Litho-sketch; which are paper litho plates. There
are supposed to be great in the classroom (I haven't tried them yet.)

I was wondering if anyone on the list had any info/experience with
lithography. I'd really like to try it this summer and I know the basic

chemicals, some don't. I looked on the web and basically kept finding
the same descriptions.
Usually when someone on list explains something, it makes a lot more
