Decorative Antique Small Glass Bowl

I believe this is an antique. I got it from my dad years ago. The glass shows some wear as photographed. This bowl tests positive with a lead test swab. I'm not sure if it is actually leaded crystal or if the lead content is too low to be crystal. It does make a bit of pretty ringing sound when I tap it with my fingernail. I recommend this for decorative purposes only.
