No. Johnson Marbonite tile is tough and long-lasting because it is manufactured using the finest raw materials. High-quality minerals are mixed with clay to form a unique body composition. 4600-ton presses compress and compact the powdered mass to form the slab. The tile is then fired in a 142 m roller hearth kiln at an ultra-high temperature of 1200ºC leading to a high degree of vitrification to make the product stronger. This process makes Johnson Marbonite tile harder than natural stones such as granite and marble. Its thickness does in no way reduce its strength and during normal use, it will never crack like a marble.
