This fired on 5" flared bowl by Hazel Atlas is part of their Ovide line in the Moderntone color gray. It is in Excellent Condition. No chips or nicks and the fired on gray remains nice and glossy. There is one very small light brown spot near the upper rim as shown in the close up photo.
The Sierra colors were this Gray, a turquoise Green, butterscotch or yellow Gold, and a Terra Cotta Rust (please see other Sierra pieces in this shop.) These were most often sold in sets with a place setting of each of these colors, but the pieces could (and can) also be purchased separately if you prefer to collect a table full of only one or two of the colors to go with your home decor colors.
**This bowl is also available in turquoise green and white in this shop. Each color is listed separately.
