Scroll Saw Blades to Cut Stone?

["james farrow" <jdfarrow@zzzzzzzzzzz>]

Hi! My name is James. I am in Mississauga, Ontario, Canada and I have
just started sculpting.
I am using my own gypsum formula and casting blocks (in a mold box) for
sculpting. The material is maybe 2 or 3 times harder than regular
gypsum. It is marbled like marble and even has the finished feel of
marble. The blocks are approximately 2" thick and the length and width
vary depending on my requirements
I have come across a problem that I am hoping someone can assist me
with.
I need to cut (straight and curved cuts) the stone from time-to-time to
get the appropriate size pieces that I need for my sculptures.
I have neen using a "scroll saw" with 15TPI blades. They cut fine but
break often. So I am hoping someone can suggest a better choice of
scroll saw blades that will perform better for my purposes. Any
suggestions?

Also, I have looked into getting a different saw but have not had much
luck in determining which one would perhaps suit my purposes better than
the scroll saw that I am now using. I did see a "Gryphon Omni-2 Wire
Saw" but it only has a vertical  throat of .35". Obviously that is not
enough. Are there any other brands of wire saws that have the throat
clearance that I need?
Any other suggestions on another type of saw? Please note I am in an
apartment so large machinery is not a viable option and am looking for a
tabletop saw.
Anyway, I better stop rambling.

Thanks & regards,

James
