Castalot for repeated firings??

Anyone tried the new product called Castalot??
(a re-useable mold material that can be used for mulitple firings)

So far I have turned up with 5 repeated castings from the first molds I made but I havent been satisfied with the finish on the glass.

The manufacturer recommends using kiln wash to coat the inside of the mold - They recommend it make the mold to hold up longer. It leaves a grainey finish on the glass. So on some firings I didnt use Kiln wash and the mold material stuck to the glass (but only a few- and some others were beautiful!) and thus hurting the mold for repeated use.

Anyone had success with a good finish and repeated firings??

Care to share the ratio of water to mold material that works best for you??

Since noone replied to my message- one has to assume y'all have no idea what I am talking about because the product " Castalot" is so new that none has tried it yet.
So my advice to serious kiln casters is to check out this new "Castalot" mold material developed by Michael Dupille. The name castalot refers to its purpose- pour a mold from it from the manufacturers recomendation of 2-1 mold material to water by volume, pre-fire, and cast into it MULTIPLE FIRINGS!!!
- Yes I have done it and YES it works! There are still some bugs I am trying to work out for me but its definitely worth investigating.
