Egg white is of great interest for many culinary and industrial applications. Egg white is used for coating, gluing, thickening and so on in pasta, desserts, etc. There is thus a great interest from the industrial point of view to better know this raw material, used in very large amounts in the dessert production for example, and to obtain egg white fractions with different functional properties.
A new distributor which can be used more perfectly for half-way development is described in this paper. The distributor is made from two microscope slides which are specially treated and glued together like a funnel. The mobile phase can be delivered to the new distributor by means of a syringe; the solution fills the capillary crack immediately and then leaks on to the thin layer plate. Development can then begin at the same starting line. Compared with the old device the distance traveled by the mobile-phase front before it becomes even (which we denote the ‘even distance’) is much lower, so the new device is more suitable for re-chromatography of two close spots. Mixtures of dyes have been used to verify this supposition, with satisfactory results.

Ammonium alum is used in tanning, in dyeing and fireproofing textiles, in vegetable glues and porcelain cements, and in water purification [ 1 ]. It is also used in cosmetic formulations such as cleansing products
due to the binder and by comparison with Fig. 8 it can be seen that the sample from Vasari is similar to casein and that of Zuccari has closer similarity to glue or egg or their mixture. This points to a difference in painting technique which is also
