What are the differences between Glass Mosaic and Vitreous Mosaic?

 Glass Mosaics:

Grip: Provides maximum contact surface for adhesion. The adhesive can be spread over the entire back surface of the mosaic. The adhesive strongly adheres, forms a single body with the mosaic surface, and does not vanish over time.
Joint Filling: Since the joint gap between the mosaics is wide enough, the applied joint adheres completely to the space between the mosaics. In this way, the joint ensures that the mosaic holds in water and does not fall off.
Thickness: The steep edges and slightly rounded surface of the mosaic provide maximum grip.  
Surface: Colors will not fade over time and remain constant. The desired texture can be achieved with Matte and Glossy finish surfaces.
Cleaning and Hygiene: Glass is a natural material. It can be used for a long time. It does not moss or hold dirt. It is easy to clean.

Vitreous Mosaics:

Grip: Provides limited contact surface for adhesion. It does not easily adhere due to glue residue between the nets, and there is a risk that it will vanish over time.
Joint Filling: There is very little joint filling area due to the slope of the vitreous mosaic mold. Joints between mosaics tend to wear out if they come into contact with water, and they are likely to fall off.
Thickness: The outward sloping edges of the mosaic provide minimal grip. 
Surface: It has a rough surface. The texture is not pleasant. Discoloration is observed over time.
Cleaning and Hygiene:  It holds dirt because of the rough surface. It is also difficult to clean.
