I have been making fresco panels of pumice, 3/8in granules, cement and lime at 12/l/l with just enough water to make the mix uniformly wet. Then pouring into frames of various sizes and lifting the form off right away. The surface of these panels is textured for an ideal key with the intonaco, as well as being absorbent light weight and easy to frame and hang. I have been doing landscapes of Martineztown, the neighborhood I live in with an easel and over the past few month have produces a couple dozen paintings. I can be reached at Nephtali @ unm.edu or my address is 1217 Edith NE apt c Albuquerque NM, 87102 I would b vry excited to receive correspondence.
