Would the bricks and mortar in the old ovens just be standard terracotta bricks and standard mortar?

The terracotta in my oven looks like it could have been made from old broken terracotta roofing tiles, because I see a slight curve to some of them. I don't know how long ago terracotta roofing tiles were being used, but I suspect it was a long time ago.

Aluminium originates in the earth in the form of a red or brownish clay called Bauxite. Bauxite ore is found in abundance in the Caribbean, Australia and Africa and estimated figures suggest that 8% of the earth’s surface contains this red clay. Bauxite is an ore, rich in aluminium oxide formed over millions of years by chemical weathering of rocks containing aluminium silicates.
Environmental Issues
Makes you wonder whether the red clay bricks naturally had a high aluminium content.

The ancient Romans were masters where concrete was concerned and many of their secrets are still undiscovered. The Pantheon in Rome is a breathtaking example. To make the dome lighter as it ascended to avoid collapse, they gradually tapered the walls getting thinner and thinner towards the top, but also they used lighter aggregate, as it rose, transporting large quantities of pumice hundreds of miles from Pompeii. when we visited I gate crashed a uni lecture on the building which was spellbinding.
