Inverted Fan and Feather Pink Slag Tumbler

Original pink slag appears as a swirl of pink and white glass. The reproduction tumbler below is actually a custard colored base glass with a flashed on swirl of pink paint. The outside and inside look quite similar to original slag. To detect this reproduction, look at the bottom of the base - the base is unpainted custard. This sample is more than 25 years old, maker unknown. Height, 4".
