I believe your bowl is by Lancaster Glass, but others made very similar items.
The Lancaster Glass Company produced pressed glass from 1908 to 1924 before they were purchased by the Hocking Glass Company. However, Lancaster continued to operate under their original name until 1937. In the 1920s and early 1930s, they produced iridescent ware, mainly marigold items.
If your bowl is Lancaster, then the pattern is "optic ray" and it was made in a mold which Lancaster used earlier to make Stretch Glass bowls in. It is not from the original Carnival Glass era, so I would just call it "marigold iridescent".
