What pigment should i use to make it black? i thinking making mugs, bowls, etc, so need to be non toxic. also, it needs to be sealed once hard?

There is no way to seal this that will be food-safe and suitable for functional ware. Dishes MUST be made using kiln-fired clay and dinnerware safe glazes.

Using this for a class -- would this be enough for 15 smallish projects?

Think of a pound a clay in terms of sticks of butter. One pound of clay would be equal to four sticks of butter. Do you think that the students would need more or less than one stick of butter for their project? It could be done with the two pound container, but the 5 pound option would give your students a little more clay to work with.

Wanting to use this as a base for a wire tree....is it heavy enough to support a heavy wire tree?!

My opinion is: it would depend on how many pounds of wet clay you use as a base would depend on how much weight it will hold and how spread out you were to make the base. I would say yes if you were to put the same wire in the base and make the base wide enough to support the weight of the tree as the wire you are using to make the tree.

would this be suitable for making basic clay marbles?

This one of the best clay available.. totally worth.. Yes it take - water, oil and ceramic paint.
