Shading Exercise - Glass/Liquid/Ice
Hope you like it
-
Unfortunately that's not what it should look like. Ice has similar IOR to water (and other liquids), so it is almost invisible. See the attached photo (left ice with air inside it, right clear ice).
-
Also, ice doesn't sink to bottom in a glass of water. :)
// Short explanation: Water starts expanding as it gets colder than 4°C (physical wonder (https://www.quora.com/Why-does-ice-float-on-water) ;). Consequently, ice is less dense & has larger volume, yet retains same amount of mass, thus it floats in same substance/matter.
Next thing, what are those stripes - on edges at the top of the glass?
-
Getting back to physics, May be it is not water in the glass, something with slightly less density like oil or alcohol.
-
Could be :)
I mainly assumed based on color of the "Liquid" (oils and similar were instantly excluded, based on probability of getting these liquids served in such arrangement). While scotch, whisky, bourbon & maybe even rum aren't strong, pure enough (based on density, drink must have at least 86% of alcohol for ice to sink to bottom). Tea or coffee are mainly water. So the only argument left for me was, that those "Ice rocks" are basically made of glass. Then they would keep cold, wouldn't melt, would sink to bottom & have different IOR. Problem could easily be solved, if title weren't so descriptive. ;)
Yet still, there's so much detail missing to stop any speculative guessing... ;)

Glass cubes in coloured water in container made of ice. Problem solved? :]

This was the photo I used as reference.
Not sure if it is ice/glass/alcohol/colored water :D

That looks more like whisky rocks to me...

I have a solution =D

I have a solution =D
Yup, i know this one - STROH - goes well in winter with alpine herbs tea, but it's still not strong enough ;)
In this polish vodka, ice goes to bottom & with a bit of stroh rum for proper color, also minds melt :D cuz we never drink alone

on the rocks :D
hard to notice, but i assume, rocks goes to bottom because tops/peaks are not submerged
ie.
