How to Identify Glass Fishing Floats?

• Look for a distinct 'seal mark' or 'pontil' where the glass was broken off the blowpipe and sealed shut.
• Examine the glass for bubbles, swirls, and imperfections characteristic of hand-blown recycled glass techniques.
• Check for authentic 'pitting' or a frosted surface texture caused by years of tumbling in sand and saltwater.
• Identify embossed Japanese kanji characters or maker symbols often found on the circular seal of the float.
