Make your own paint?

As if we didn't already have enough on our "to do" list, now we can make our own paint.
(There's also a website that shows you how to make your own chocolate, but we won't go there)
For artists who want to know more about how their materials are made and where they come from, paintmaking.com is a valuable resource. It tells you the pros & cons (“There are lots of reasons to make paint, and plenty of reasons not to.”) It might be helpful to understand more about your materials; maybe it will lead to new ease and confidence in your work or even to renewed inspiration. Maybe there are certain colors you want that can be mixed in volume from your own recipes. You can save money, especially if you're using the less expensive pigments. Of course, this all takes time to learn as well as to make, and maybe you would rather just do the painting. And it can be a boring job (lots of mixing).

There is a long list of FAQs and web resources, along with information about all different media – acrylics, tempera, watercolor & gouache, oils & alkyds, encaustic & fresco as well as chalks. There are tools, supplies, ingredients and binders. There is even a “History” page, starting with prehistory and going through Egypt, Greece and on up to the 20th century. And there is information about safety as well.
