Someone in my group asked about the above. I thought that other people might be interested in the answer, so here it is!
Twinkling H2Os are very sparkly watercolors. They are cakes that you have to moisten to work. The colors are very brilliant. I use the little misters when I use the H2Os. Unless you use a lot of one color, the little pots last a long time. I have a bunch of the little ones and have not run out yet. They do get a little nasty at the end. I drain the rest of the color onto scrap and let dry. BTW, I don't bother putting the lids back on. I just leave them off to let the cake dry. I put them in a container when not in use.
Radiant Rain misters are Twinkling H2Os in liquid form. Shake well often while using or the mica powder sinks to the bottom. Often problem with sprayer - mica clogs the nozzle. What I do it shake it up and pour a little into a mister. I use the stuff in the mister and refill as needed. When done, I pour it back into its original bottle and rinse out the mister. Solves clog problem. I hate standing there letting it run under hot water.
I love the misters. I use them on top of technique sheets all the time. My favorite is solar gold. Don't overdo it though. The look is very different dry than when it is wet. Experiment with a little at first. You don't want to ruin what you have done. Some of the colors are more dominant than others. My blog and the techniques blog have some techniques on there using the Radiant Rain misters.
I have not tried the daubers yet. I will let you know when I try it. I don't want to tell you the wrong thing. I don't know if it is more like acrylic or watercolor.
Primary Elements are also called Polished Pigments. They are the concentrated form where you need to add a solution to it to get it to the consistency that you want to work with it. They are shimmery acrylic paints. I have not gotten them yet but will post my experiments once I try them. Bernie Berlin has been working with them. It is on her blog.

Now that you have an idea of what they are. It is up to you to come up with ways to try it. You can buy it at their site. They also have a retail store locator on their site. I buy a lot of the Luminarte stuff from franticstamper.com.
