yours was blue because there are two types of catalyst.. the 6 hour demold is blue.. the 24 hour demold is green. as for the clay, i tested it and it worked great...maybe it was just your clay and the type of object you were putting the clay on. as for soggy in the middle, you are supposed to wait at least 24 hours... depending on your catalyst. however you have to be precise in measuring. there is basically supposed to be a 10% catalyst mixture with the silicone, but it will work with a 8% - 12% any more or less and the results may not be desireable..
