alabaster surface treatment

Surface treatment for alabaster

Although the aesthetic qualities of alabaster are rich, its natural technical characteristics can pose a challenge. In order to protect the material over time, and still reveal its natural beauty, Atelier Alain Ellouz has developed specific techniques called Stonelight.

The constraints of alabaster

fragil

The richness of patterns within the alabaster is due to variation in density and crystallization. Amongst those are fragile veins where the alabaster plate may weaken.

rayur

The gypsum alabaster that we use has a hardness between 1.5 and 2, which is low (marble is 4-5, quartz is 7, and diamond 10), and prone to scratching.

impact

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.

poreux

Untreated alabaster is porous, and penetrating liquids may stain.

UV

Alabaster’s specific crystallization which gives it its transparency  is unstable under the sun. It will naturally darken and yellow under UV rays and exterior aggressions.

Stonelight solutions

rigidification

Strengthening treatment

This technique encloses the alabaster within an invisible structure, thus adding resistance to flex.

protec ray choc

Shock and scratch protection

This treatment encapsulates the alabaster within one or more layers according to usage: a SOLO Art will recieve a lighter treatment than a SOLO Furnishing integrated into a bar top.

protec liquid

Sealing the surface

This treatment seals every pore of the surface, and permits resistance against different degrees of aggresivity.

protec UV

Anti UV treatment

This treatment is applied to those pieces which will be exposed to daylight.
The transparent qualities are then preserved.

Protection levels according to the use of the SOLO

The Stonelight level indicators is composed of three numbers, corresponding to three levels of alabaster protection for strengthening, shock resistance, and waterproofing. It is followed by the UV sign when the object will be exposed to UV light.
