It can be given with glue, two or three times, as I told you before, at the small works and Gingase; And yes with IPSOS only for a while, and what practice you will teach you. In what way do you have to go with glue SL SA rub our plaster for reliefs? There are still many who rub the plaster only with glue and water. This is good to grump with plaster where it is not Grandlet with great plaster, asking to be stronger with glue. This plaster is very good to highlight leaves and other works we often need. But when you make this plaster, put in a little Huma by Armenia (Bol), so much to give him a little color. In what way do you have to start a burnt panel surface with plaster marunt?
When you have finished grunts with plaster (thing to do one day, and, if necessary, work at night until you're done everything), let it dry - • Not in the sun -, at least two days and Two nights: because, the more you leave, the better. Take a carbon powder bag, tied as a small ball, and starts to shrive coal over the plaster on this panel. After that, with a pomatus of gain or gymca, sweep and smoothes this black powder all over the plaster. And this, because the surface can not be shrugged too smooth, and because the iron that razes the plaster, being wide, where it razes, the place remains white as milk. Then the black shows you where you have to crave. How should I scare the plaster on the panels, and what is this good? First, a long rajfietto and a finger, and care around the surface raising - from a breath - the whole cornisa.
Then, with the razor knuts, razing by smoothing as best; And, with a light hand, holding the razor knife without somehow strengthening a mine, rub the surface of the panel, maturing the plaster with the penetration, as we have shown above. And you know that this maturation is good to remove oil stains on the cards' sheets. And, in the same way, with your iron tools, rays the cornis and the fries, and polish them until they come as the ivory. And sometimes, (when you are rushed and you have a lot of work to do), you can polish the cornis and the fries just with a piece of canvas - wettata st squeezed -, knowing these horns and strips well. How do you start drawing with charcoal on the panel, and how it strengthens in the ink? The plaster, being welcomed and polished until it comes as the ivory, the first thing you have to do is draw on the panel or on the wooden board with those willow coals, which I have learned before how to do it. But you have to turn on coal of a stick or wand, so that it is of the length of the figure; Because it will help you a lot to compose what you put yourself in thinking.
And to prepare a until, because when any trait did not seem to be done, you can delete it, and then draw it again. And draws light hand, and shadows the creases and faces just as you would do with the brush, or how you would do with the "in the Penita". When you have finished drawing the figure (especially if it's a high-priced panel, from which you wait for cis-tig and the diamath), let it stay a few days, returning from time to time to it and indrcptind where you think it must. When you seem almost good (you can copy and see works made by other good craftsmen because there is no shame for you), and your figure will only be won; Take a little bit over the drawing, until you did almost disappear, but not yet you can not understand the traits made by you. And take, in a vasular, half clean water and a few drops of ink; And, with a small, sharp brush, as a squirrel hair, begins and strengthens the whole drawing. Then take a pure-tuff of feathers, and mature on drawing all coal powder. After that, take a watercolor in that ink, and with a soft brush, the squirrel hair, shadows some cutes and some shadows of the face.
And this is how you will remain a full of Gingasia, that it will not be someone who does not like your works.
