If it is on the inside then observation across the edge of the glass in the thicker parts will show a halo of clear beyond the inside color (which carries through on direct viewing.) No halo, then it is solid. The amount of gold in the glass is trivial, what makes the red valuable is the difficulting in making a good red that does not turn a muddy brown while working the glass.
