Building brick are fired at lower temperatures for shorter periods of time. They contain higher water content, are more porous and therefore absorb more water.
That’s why building brick are inferior for paver construction. They lack compression strength, and can absorb 3X their weight in water, causing them to crack and disintegrate.
Molded brick have a rough appearance, they may have a sandy - gritty surface. Sand is used as a lubricant to remove the brick from the mold.
