ALABASTER PROTECTION STONELIGHT
20Pages

The Stonelight treatments Although alabaster has rich aesthetic qualities, these are offset by the constraints presented by its natural technical features – these include a lack of hardness (2), sensitivity to heat and shocks and roughness of surface. The Atelier Alain Ellouz has taken up the challenge of adapting alabaster for use in work demanding robustness and impermeability, such as bars or floors. The specific Stonelight techniques, involving a series of applications of resins and varnishes, give alabaster all the qualities required: rigidity, resistance to shocks and protection...

The richness of the patterns within the alabaster are due to the variations in density and crystallisation. The alabaster may weaken around the (fragile) veins. The gypsun alabaster that we use has a hardness of 1.5 to 2, which is low and therefore prone to scratching. (Marble is 4-5, quartz is 7, and diamond 10). Alabaster is sensitive to heat and shock. At 70°C its inner structure is altered and the stone looses its transparency. Any impact on untreated alabaster leaves a dull white mark on the surface of the stone. Untreated alabaster is porous and penetrating liquids may stain....

Strengthening treatment This technique encloses the alabaster in an invisible structure, thus adding resistance to flex. Shock and scratch protection This treatment encapsulates the alabaster within one or more layers according to usage. Sealing the surface This treatment seals every pore of the surface and permits resistance against different degrees of aggresivity. Anti UV treatment This treatment is applied to those pieces which will be exposed to daylight. The transparent qualities are then preserved.

The contribution of light The apparent whiteness of alabaster reveals the richness of its patterns as soon as it is back-lit. The 15 or 20 mm of translucent materials play upon the clarity of the surface and the softness of the interior motifs. Alabaster is the true embodiment of chiaroscuro. Once lit, this fascinating stone possesses an amazing power of attraction. The relationship between form and light The Atelier Alain Ellouz favours a very contemporary approach with mass lighting, which eliminates the effects of transparency. In this way, alabaster itself becomes the light source...

Soft to the touch With the finishes, our artisans ensure that a soft and pleasant tactile contact with the stone is preserved. Alabaster has a warm feel (like wood) which reinforces its soft and warm look. The satin finish, obtained through controlled polishing after treatment, gives an optimal and authentic look rising from the depths of the back-lit stone.

L’Atelier Alain Ellouz a mis au point plusieurs techniques de rétroéclairage particulièrement adaptées à l’albâtre pour valoriser ses qualités de transparence. MAÎTRISE DE LA DIFFUSION Pour tous les projets, les positionnements de sources du retroéclairage sont mises au point afin de donner un rendu de lumière très homogène. MAÎTRISE DE LA COULEUR Le mélange de deux sources variables, blanc chaud et blanc froid donne toute une palette de températures de couleur possibles pour choisir le meilleur rendu de l’albâtre selon l’ambiance désirée.
