The fresco studio:
iLia said that fresco painting does not have to be that expensive. To save on the cost of slaked lime, one can paint with 2 coats (or even on just one). He can thinly plaster a previous fresco, and use that for a support. He can even do practice frescoes with cheap and available Home Depot lime (which has too much magesium for the best buon fresco painting), after slaking that lime for as little as a week (or even less). Moreover, one might save on dry pigments if he buys them from a masonary supply shop. In short, students should not be discouraged from painting in fresco, because they can easily start with cheap materials.
iLia painted this fresco on Home Depot lime:
One layer fresco on a burlap-like cloth support:
The important thing is to get a feel for your lime plaster. Wall frescoes are often painted on 5 layers of lime plaster, but those layers can work against the artist, if they wick the water out of the top coat too fast, and cause the surface of a fresco painting to dry too fast and crack. Conversely, if those underlayers are saturated with water, they can keep the surface layer wet for a long time, and painfully delay the painting process.
Moreover, iLia said that one can midst the fresco plaster with an atomizer, during painting and even after the painting is finished, to keep it from drying too fast and cracking. In fact, misting can make the fresco stronger, as it does with concrete.
If one paints on the fresco plaster while it is still wet, he will mix his pigments with the lime, and the final fresco will suffer dull colors. However, when the surface is dry enough to absorb the ground pigments, the artist can glaze thinly with color, and the fresco will radiate with vibrant colors when it dries and cures.

Fredercio Vigil painted this fresco at SPARC (Social and Public Art Resource Center) near Venice Beach:

I did not see the Orozco fresco, but note that there are 2 frescoes at Pomona College (the other by Rico LeBrun).
Siqueiros painted a "fresco" -- America Tropical -- in downtown Los Angeles "made of cement rather than the traditional plaster, (which) was completed the night before its dedication on October 9, 1932." In 1938 this masterpiece was white washed over and forgotten. Now this mural on Olvera Street is currently being restored under a multi-million dollar contract, though it is not yet open to the public (Aug 2012).

Between the examples of iLia and Siqueiros, I'm inspired to try painting "fresco" on Rocalite, the translucent concrete additive from Mexico. Unlike regular concrete, Rocalite does not set up for 3 hours, giving the artist plenty of time to paint pigments on the surface:
