Weight of VG?

[Leni]

I find VG to be a PITA to work with, it’s easier if it’s warmed through a bit. What I hadn’t considered is whether or not the weight of VG changes when it’s effectively ‘melted’ somewhat. I could check this myself, but first off is there anyone who mixes by weight that already knows the answer to my question please? Does the weight of VG change when it’s warmed?

I usually add 5% distilled water, makes it easier to work with.

The volume will expand when warmer but I'm pretty sure the weight will remain the same.

Volume increases with heat, mass remains constant, as you say.
VG is said to be 1.27g per ml, and PG 1.04 per ml. Both at room temperature.
But I'll bet you get 100 different answers. Lol

Pg = 1.038. VG = 1.26

 

[RAPTOREX]

Pg = 1.038. VG = 1.26

didn't I say, @Leni lol
In the main, the difference is down the the temperature when the specific gravity is measured. But equally it can be down to slight variations in proportions during mixing of the ingredients used in manufacture.

and here in lies the problem with trying to produce both weight and volume recipes. The two measurements can't really be converted, and are defiantly not interchangeable, within a recipe.
Now the question as to if these variations really matter, is a whole other thread entirely.

Sorry @RAPTOREX , I couldn't resist it.

It's fair to say that the slight differences will be pretty small in the scheme of things and won't really make that much difference.

Exactly, the warmer things get, the larger they get.
That's why the daytime is longer in the summer, than the winter.
Amazing stuff science is.

And there's me thinking the days in the winter are shorter cos they weigh less
