• The combination of silex or alumina and an alkali in proper portions always yields a fusible, easy-running compound.

• The bed of the road was first properly prepared, and then it was paved with polygonal blocks of blue basalt called silex.

• Silex is another volcanic stone very little used for building, but entirely for paving the roads both ancient and modern.

• Then, on the terrace above, there is an arcade paved with blocks of silex, and on one side shops.
