AKRO SPARKLERS

Sparklers were Akro Agate's only marble that was manufactured with the "injection" method, where colors were actually injected into the clear base. This was essentially the same technique used to produce catseye marbles, which came much later and which were not produced by Akro (since the company folded before they became popular). Sparklers are often mistaken for Master Marble Sunbursts, though this should not happen, as Sparklers always have at least five colors (with rare exceptions) while Sunbursts have no more than three. Also, the colors used in Sparklers are very bright, whereas Sunbursts are normally duller or more earth-toned. Typical Sparkler colors are red, yellow, orange, green, blue, and white, and these will form a wispy core in the marble. Less often, the colors will be in bands. Sometimes these colors come almost to the surface while at other times they are closer to the core.
