I'm constantly getting asked about the equipment needed for processing natural pigments, so I've made a quick equipment list for you! I'll try to expand on this over time, but these basics will get you started!
You'll need a frosted glass plate, but traditional sets are very pricey. To save on costs I recommend using etching liquid to frost the surface yourself.
Simply paint on the etching liquid with a regular brush, let it sit for about 15 minutes, then rinse. Wear gloves and do this outdoors!
Here is a good quality mortar and pestle set.
If you want a beautiful vintage one, I suggest the State Line Flea (only open on Sundays near Whitehall, NY –last time I was there they had a TON of beautiful vintage ones, this is where I got my favorite one).
Glass Muller for adding your binder.
Watercolor medium / gum arabic
(a powdered version is available at Sparrow Art Supply here in Middlebury–just add hot water to dissolve).
Vegetable Glycerin (not 100 necessary, but a drop or two improves quality of dried watercolor paints):
The advantage of using this one is that it doesn't introduce aluminum into the equation (which may shift color). This one also comes with its own paper filters!
dissolve about 1 TB per 1 cup of hot water
dissolve about 1 TB per 1 cup of hot water
PH test paper (aim for a neutral PH of 7)
palette knife set of 2
Clove bud essential oil (a drop or two helps prevent mold in inks and watercolors)
once you've finished making a watercolor, it can be poured and left to dry. I use these half pans for my palette sets, or you can always pour your color into a shell or acorn top for added charm. These craft syringes will help you get the perfect pour.
You'll also need various jars for straining and pouring liquid back and forth, and spoons for stirring, etc. Plants can be simmered in an old pot. Stainless steel is recommended so as to avoid color shifts, but if all you have is aluminum that will work just fine. Remember not to use anything for food after you've used it to make paint!
That's it! With very little investment in equipment, a world of color is at your finger tips. Enjoy the process and please share your results!
