Day 390-Ice Blue mini with copper rim
When I visited Blenko in 2012, I asked how the copper rim was applied to the rim of the Seabreeze bottle. I guessed at first that the same copper tube used to make the spouts was somehow used to apply copper to the rim although I wondered why it was only seen on Seabreeze glass. It turns out that a “copper compound” is used as one of the colorants in Seabreeze and if the Seabreeze glass is overheated the copper re-forms on the surface of the glass. This formulation of Ice Blue is Blenko’s Turquoise cased in Crystal. I figure that Blenko must use copper oxide to produce it’s Turquoise color (this is an industry standard colorant.) Now I wonder why I have never seen this happen on any Turquoise water bottles. This mini is a beautiful example as the copper rim and pink shading are easily visible from the side where in the few Seabreeze examples I have seen, the rim almost has to be seen from the top to notice the copper color.
