Tabitha: great tip with the moss! Always looking for more search tag ideas, that is a good one, thanks
Northland: I wonder what the Emerald city smells like? Especially with rainbow hued horse of many color droppings littering the streets...
Twilitr: Great extension of the Emerald Idea, thanks!
Woodi: Yeah, this is a clear M&P. My methods are pretty insane...but since you asked: this is a combination of four different colors, mixed and cooled in separate containers, then when it is just barely set up I cut some of the material into thin ribbons using a cheese slicer and tear the rest into smallish pieces. I then take a gold mica suspended in glycerin and dabble that onto the clear pieces. Next we dump the whole thing into a heated chamber that I made and use a big, heavy stick to agitate the material into a semi-paste that mixes all the stuff together. Very, very touchy as clear m&p will turn white if you over do it. In the end I have a big ol' brick that I cut into these bars.
Back in the 90's I had a job mixing colors and doing R&D for a soap company called TSPink (the owner is an artist who trained and inspired me to see the wonderful expressive potential of clear soap). I got paid to play with hundreds of pounds of M&P that I didn't have to pay for, total dream job (until it got all corporate). My point is, I wouldn't recommend trying something like this as the potential for failure is pretty substantial. If you are interested I would be happy to make a tutorial or two about getting some cool fx with clear M&P that are much easier to achieve.
Thanks to you all for your input, it really does help me to get as many different perspectives as I can. You guys rock!
