"...metal joiners were either pounded in to the holes, or molten metal poured in to fill the channels. The same technique was used here and there in pharaonic Egypt."

I'm pretty sure it was poured. What was the metal, bronze?

The Greeks used bronze clamps in dog-bone or ' I ' shapes to tie blocks together. The 'T' shaped recesses chiseled into the ends of the blocks were oversize, allowing a fill of molten lead to be poured in to perfectly fill the spaces. The bronze gave strength, the lead filler formed a cushion between bronze and stone while also protecting the bronze from corrosion.
