How it works
Fresco has two methods: buon fresco on wet plaster and secco on dry. Both fit a tile of plaster of Paris that an adult mixes and pours, so the 60 ideas are small: a fish, a border, a painted window.

Buon fresco: wet plaster, one sitting
The paint is absorbed into wet plaster, which is why it lasts, and the drying plaster sets the deadline. So the three wet groups are quick: a few earth colors, shapes done in one pass and the bare plaster for white. The third paints one picture across several tiles, a tile a day.
Secco: dry plaster, fine detail and blue
Secco goes on dry plaster, alone or over a fresco that has dried, and its paint needs a binder such as egg, glue or oil. Painters used it for changes, small details and blue, which worked badly on wet plaster. A kingfisher on a reed, every feather edge drawn fine, is detail and blue at once.
- A wet idea needs the tile still damp, so pour it the day you paint.
Questions and answers
What are some ideas for fresco painting in a class?
Ones that fit a tile each: Round tile filled by a smiling sun, short rays to the rim; Zigzag band with a dot in every notch; Mouse looking out of a hole painted on the tile. Easy first tiles holds 18 like them.
Is buon fresco or fresco secco easier?
Secco. It is quicker, a mistake can be corrected, and the colors change less as they dry. Buon fresco lasts better: a picture painted wholly on dry plaster tends to flake away.
Can you paint a fresco on plaster of Paris?
Not a true one. The plaster of true fresco is lime, and the lime setting in air is what fixes the color. A plaster of Paris tile gives the same practice, painting damp plaster against the clock, on a picture small enough to keep.
What is a giornata in fresco painting?
A day's work: the patch of fresh plaster laid for one day's painting. The seams between days were nearly invisible at first and can show centuries later. The garden wall across three tiles, one fruit tree to a tile, puts its seams between the trees.
