Decided I had to try one of these air dry clays I purchased a while ago before they turn to stone on me. This particular one is a clay called Marblex by Amaco. Had the same problem you all mentioned in that this clay has a really limited workability time. After only a half hour of working time I noticed a remarkable drying of the entire piece, which I didn't like. I spent a total of 1 1/2 hrs on this (which is why it looks so odd) and had to do several repairs as the legs were drying so quickly that they started becomming brittle as I worked on other areas.
I suppose I should have chosen a different subject with no thin areas such as these legs but I wanted to see just how brittle the piece is after drying. The box said you cannot use an armature due to the shrinkage and what a challenge it is working with a clay that wants to slump and have no armature inside. It also said the piece should be hollowed out, which makes sense for more even drying. I will say that after just over an hour it was firm enough to handle to easily hollow out. I covered with damp cloths and we will see what happens in a day or two. You will probably see a crumbled mess in the next pic :D
