Ginger Jars



One and two pound hexagonal ginger jars all from BC. The green colour is more common in these. Red occurs due to reduction firing of the copper content of the glaze. In reduction, the firing chamber is oxygen starved which causes some of the compounds in the glaze to take oxygen from other compounds, producing the red colour when copper is present. When there is plenty of oxygen available the same changes do not occur during firing as those compounds requiring oxygen will take it from the environment instead of from other compounds in the glaze, thus producing the green glaze when copper is present.



The hexagonal green ginger jar collection consists of 17 jars of the 4 pound, 2 pound and 1 pound sizes from BC and the USA. The 4 pound size is comparatively rare. They have been collected for size, colour, different side wall panel designs and different collar designs, lids, labels, and basketry. The following images show these in rows, first the three 4 pound jars, then the five 2 pound jars followed by the 1 pound jars.









Older gingers: 4 pound, 2 pound and 1 pound-- undecorated or with one or more lines. Someone painted the 3rd pot in the first row.





The label on the lid of the 4th jar in the first row above:



Three old small gingers with partial green glaze. The one on the left has two seal impressions along the shoulder of the pot. The one on the right is the wide mouth variety.



Fancier ginger jars-- shards of the two pictorial jars are sometimes found in digs which makes the shard easy to identify.
