The Bologna Chalk is used in gilding to prepare the “ammanitura”, a specific basecoat for the preparation of the surface to be decorated with gold leaf. Has a great softness to the touch, given by the fineness of the grain of which it is composed. It is also useful in the preparation of fillers to be used on various occasions and in general in the realization of high quality decorations.

Prepare the rabbit glue, following the procedure described in the data sheet. After applying the basecoat “colletta” (primer), dissolve in a water bath in the small pot for gilders 350 gr Bologna Chalk in half liter of “colletta”.
Pass the mixture still hot on the wood (ammanitura). This procedure will be repeated for the various coats that will be applied (it can take up to 5 or 6), always with hot mixture. After each coat has dried, we will pass on the chalk surface with coarse sandpaper (120-180).
Finally, once obtained a satisfactory base, the surface will be trimmed and polished on the edges and on the notches by using the scraping tools, of appropriate shape, trimming chalk in excess, in order to revitalize the edges and the decorations.
Then sand gradually with a finer sandpaper (350-600) to remove any remaining imperfections.
