Bubbles in a cocktail shaker (split from Help with Glass Pear)
« on: January 10, 2007, 10:06:36 PM »
A bubble-related question from a definite novice...

Are controlled bubbles indicative of any particular period or country? I picked up this cocktail shaker (sorry, terrible pic) a couple of months ago and would be fascinated to know anything more about it. I love the way the bubbles are stretched by the form of the shaker. The shade of green on the base says either 20s/30s or 50s to be, but that's very unscientific.

grrrr while I was answering

Controlled bubbles are indicative of the use of a mould, I think there is a picture of one lurking somewhere around these forums. Basically a mould with lots of points.

The item (Blob of glass on the end of the pole) is dipped into the mould and then (cased) covered in more glass, wherever the points pushed the first layer in, a small amount of air is trapped creating a bubble.

The bubbles can be distorted by manipulations.

In fact they can be added by hand with a pinwheel or just a pricker.

Random shaped bubbles are created by sprinkling vapourising granules onto the item before casing.
