AKRO SLAGS

Akro Agate slags ("Striped Onyxes") were available in the following colors (in increasing order of rarity): amber, purple, blue, green, red, aqua, clear, vaseline, and orange. The red slags were called Cardinal Reds by the company. Like the slags of other companies, those of Akro were produced by the single-stream method and include a transparent colored based mixed with opaque white glass. One exception is the Cornelian which was produced in the same method as a slag but consists of an opaque red base mixed with opaque white. Perhaps the best way to identify an Akro Agate slag is not by any particular feature but rather by its lack of features. Akro Agate slags will lack the seams seen in Christensen Agate and Peltier examples, the fine feathering of the white seen in Peltier examples, and the "nine and tail" of the white as well as the cut-off mark of M.F. Christensen examples. As to the latter rule of thumb, it needs to be stated that early Akro slags, like those of M.F. Christensen and Christensen Agate, were hand-gathered and therefore may exhibit the "nine"-shaped pattern of the white where the marble was twisted out of the glass furnace.
