I have a very nice bright green and white slag glass ruffled bowl here. It was manufactured by the Westmoreland Glass Co. somewhere around 1972. According to E. Ward Russell & Walter De Vine this was the only year that Westmoreland produced slag glass. They called it “marble” glass. This piece looks a lot like Fenton.
This bowl is in excellent condition. Take a look at the pictures, and if you have any questions, please e-mail.
