Tossed it here in General Cooking because I didn't know where else to put it.
How do they get such clear ice?
When I freeze water it always has bubbles and/or a haze to it.
True I really only make ice cubes but I wonder what makes the glass perfect ice used in sculptures?
Do they vibrate while freezing to remove entrenched air?
Is the tempreture and/or speed of freezing a factor?
Is the water filtered through a special medium to attain clarity?
I did a search here and came up with this thread.
Notice the bear has imperfections you don't usually see.
TL mentioned boiling the water before freezing.
Is that all there is to it?
Lots of boiling and large containers to product those big blocks of crystal clear ice we see used for those fine sculptures.
Yeah I could Google away but I figured it would be fun to throw it out to you good folks for the answer.
I'm sure it's in the collective DC knowledge base somewhere.
Oh and I found this gem while searching.
