I’m very proud of the two 18th century onion bottles at Noordermeer Antiques. When I see a picture of a good early New England home they always have a couple of these on the table. The name only identifies the shape. They have extra wide bases for stability and concave bottoms for displacing the sediment of the less than perfectly filtered wine. These bottles have wonderful personality enhanced by their imperfections and asymmetrical shape. When looking at old glass always look for a hand formed mouth and an applied slip of molten glass to form a lip. They are often referred to as black bottles but in reality they are very dark green. They can be found in different shades of green and even in amber. These bottles were used for oils, spirits and actually im sure any liquid could have been found in these beautiful bottles.
