Pool that was re-plastered in November of 2006 Plaster has become very rough with blue specks showing in it. The pool was also converted to a salt water system. A bad plaster job or something else?

What has been your chemistry balance for the year - month-to-month? Without seeing the pool finish, it seems that your pH and alkalinity have been off for months. What chemicals do you add regularly or on a weekly basis? I have much doubt that it was the conversion to salt. A bad plaster job would have other signs. Please, get back to me thru my message board. So that I can further analyze situation.

Why is the plaster on a gunite pool gray in the middle and white on the gunite side and white on the outside?
The finish plaster is normally white all the way through. It sounds like you are dealing with a pool that has been replastered by the method of putting a "brown coat"/"scratch coat" (the gray plaster you noted) over the original finish plaster surface, and a new finish coat of white plaster on top of that. The scratch coat more like a thin concrete than plaster (doesn't have the white marble dust in it) and is used to get a better bond to the old surface.

Will plaster of Paris dissolve if used inside a home made snow globe?
Yes, so the plaster will need some type of water-proof coating. If you are carving something from a plaster block, moulding something out of plaster, or even using a pre-made plaster object, the only way it will not slowly dissolve in the water of the snow globe, is to make sure it is totally covered in some type of water-proof finish. I'd use a minimum of 2 coats to make sure. If there is even a small break in the finish for the distilled water to get under, your finish will begin to peel and the plaster will break down there.
