O'HARA / LOOP LOW FOOTED BOWL, deep fiery opalesc

O'HARA / LOOP LOW FOOTED BOWL, deep fiery opalescent teal blue, made from the large sugar bowl base which was flattened and expanded outward and the rim turned up, six large scallops, short hexagonal stem and circular single step foot, one-piece construction. Probably Jas. B. Lyon & Co., Pittsburgh. 1860-1870. 3 1/4" h, 9" to 9 1/4" dia rim, 3 7/8" dia foot.
Reference: Wilson/Toledo, fig. 798...
Provenance: From an old California collection.
Note: This bowl has been erroneously attributed to both Bakewell and M'Kee in the past. The attribution apparently has been based on the misidentification of this as a "Broad Flute saucer" on page 25 of the Bakewell, Pears & Co. (ca. 1875) catalog. This catalog page is also reprinted in Lee/EAPG, pl. 17, which is the source cited in Spillman, fig. 960, and Wilson/Toledo, fig. 798. See Stoudt's M'Kee, pg. 167 for another "Broad Flute saucer" which is illustrated in the M'Kee & Brothers catalog of 1871. This is also apparently the basis for the M'Kee attribution. A search of both catalogs fails to locate any articles in the O'Hara/Loop pattern. On the other hand, Innes, pl. 329 reprints page 14 from the Jas. B. Lyon & Co. catalog of 1861, which illustrates a large and a small covered sugar in the "O'Hara" pattern. These both have a short hexagonal stem and circular single-step foot which is identical to the bowl above. See Green Valley Auctions' 9/28/01 catalog, lot #341, for a fiery opalescent example of this bowl, which was not fully expanded and still showed evidence of the interior lid rim.
