Interesting charts on viscosity of Aqueous Glycerine and Vapor Pressure and Boiling point - for different solutions of glycerine and water.
Heres some data on PG - not as complete - but I was looking for viscosity. http://msdssearch.dow.com/Published...ycol/pdfs/noreg/117-01619.pdf&fromPage=GetDoc
PG 100% @ 25C 77F - viscosity 48.6 Centipose, boils at 187C
VG 100% @ 20C 68F - viscosity 1410 Centipose, boils at 290C, vapor pressure 64 mm hg @ 100C
Aqueous solutions - non-VG part is water
VG 98% @ 20C 68F - viscosity 939 Centipose, boils at 208C, vapor pressure 107 mm hg @ 100C
VG 95% @ 20C 68F - viscosity 523 Centipose, boils at 164C, vapor pressure 162 mm hg @ 100C
VG 90% @ 20C 68F - viscosity 219 Centipose, boils at 138C, vapor pressure 247 mm hg @ 100C
VG 85% @ 20C 68F - viscosity 109 Centipose, boils at 127C, vapor pressure 326 mm hg @ 100C
VG 80% @ 20C 68F - viscosity 60.1 Centipose, boils at 121C, vapor pressure 396 mm hg @ 100C
VG 75% @ 20C 68F - viscosity 35.5 Centipose, boils at 116C, vapor pressure 450 mm hg @ 100C
So water has a big effect on glycerine. I knew it thinned out VG-Heavy juices to wick better but hadn't expected a little water to change boiling point and vapor pressure so much - should vape better or let you turn down the wattage?
I know PG likes water but not how much effect water has on PG.
If you add 5% distilled or saline water to your mix, how much is snatched by the PG and how much by the VG? Does it mater if you mix the water into the VG first and then add the PG stuff?
Anyway saw a lot of water/saline discussion and a bunch of ?dutch?danish? recipes that all included some water and/or saline and figured these links would be interesting here.
