Hi,  I recently purchased some soft white clay at this Asian mall near my house.  The women there had a beautiful selection miniatures made from this clay.  They even do classes!  So I purchased some of this to test it out.  However, all they told me was that it was from Japan.  I love the texture, different from the sculpey i've used for so long.  After browsing this forum, I figured this clay must be the Japanese Luna Clay mentioned on here.  It's really fun to work with - but I find that if you work it too much - it dries out and gets tough, unlike the polymer clays that could be used over and over.  Also, this one is air dried, not baked.  That's all I really know about this stuff. 

But, what exactly is it? What is it made of?  I even purchased the solutions used to make the clear liquid forms (ex/ to make ur miniature soup, or cup of coffee).  But they were just sold in be as "Bottled A" and "Bottle B".  I was told to mix them together and let it set.. and that on their own neither will set.  However, they couldn't tell me what these solutions actually are.  I'm sure someone in this forum must know.

I would appreciate any insight on this clay or the solutions. 

Thanks!
