Porphyry stone has been used for paving since ancient times



Porphyry stone has been used for paving since ancient times. Many of these roads, plazas and walkways are still in use today – testament to its durability. It is distinguished by the richness of its coloration– porphyry means purple in Greek – and its characteristic purplish- red or greenish- brown color have made it a popular choice over centuries as a building material.

Porphyry – extrusive ignimbrite – is formed under such intense heat and pressure that it is denser than most granite. Because of its density, Porphyry is non-absorbent. That feature makes it impervious to cracking – water can't penetrate to freeze and expand as with other stones. Porphyry has an even yet textured surface. Due to the hardness of the minerals it contains, Porphyry pavers do not become smooth from wear or slippery when wet.

Variation in color is a significant characteristic of Porphyry stone. Predominant colors are grey and red, but can range into reddish-brown, violet-grey, even pink, with rare intrusions of brown, green or gold. Occasionally, the stone will reveal the delicate tracery of fossils, contributing to its complexity and uniqueness.

In general, grey Porphyry is more uniform, and reads as more solidly grey once installed. The red stone is rich with earthy warm hues.
