This example carries an exceptional feature combination: a rare light cornflower blue glass tone (far less common than aqua or green Atlas jars) combined with heavy seed bubble activity throughout the glass. Seed bubbles — trapped air pockets frozen into the glass during manufacture — are a hallmark of hand-process and early machine-blown glass, and collectors prize them as evidence of authentic pre-industrial production.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Very good.
