Without a doubt, one of the crafts that look best and that take more work, are those that must be carried out on large surfaces. This is the case that we bring to the workbench today: a beautiful artisan work with ceramics, on old or dingy walls.
In this case, we are going to work with remains of ceramics or whole old ceramics, which we can break. A first step, then, is to get small (or at least malleable) pieces of ceramic, of irregular shape.
A second step to achieve our ceramic crafts, It will be to adhere the pieces of ceramic to the wall, with some universal glue or with a mixture for walls (the same that the bricklayers do).
What should be made on the wall, is a concrete drawing or an abstract creation, as long as it has a correlation. For this reason, it is suggested to the artisan, to work on small wall surfaces, which should not exceed one square meter.
In this way, the ceramic pieces will be glued one next to the other, until the wall is completely covered. In this way, the artisan work with ceramics, it will become a beautiful mural.
