This batch of ceramic pieces most likely originated as insulators. There is definitely an old sparkplug along with radio parts. Each was found along a Pacific Coast shore, by us, by hand over many decades of hunting.

The pieces do have at least one rough edge or chip; perfect for crafts, mosaics, art and some jewelry. The largest piece measures 3.7cm long, and others are smaller. US dime in photo for size reference. This photo shows the reverse sides too.

The beach gems will arrive with a card that tells the short story of sea glass and the name of the ocean where your pieces were found.
