A couple of recent purchases, it was not the common shape of ZA that attracted my interest, but the unusual colour schemes in each of the bowls.The colour code 238 bowl is more lime green than shown, the bubble inclusion covers the bowl completely with none of them burst. The colour code 239 bowl has a white top and the same lime green as 238, if you hold it up to light the bottom half appears to be clear glass with the lime green can only be seen around the top. When viewed from any other angle the lime green is seen throughout the bowl.
