VG Flashpoint huh?

[MotherNatural]

vaping 100% VG has it's unique disadvantages that I won't get into here. But I just read this on Nude Nicotine's site. Can anyone translate this into more understandable terms please?
In addition, with liquids containing VG, the vaper must be conscious to vape within range of VG’s flash point (176C). Vaporizing eliquid is a function of atomizing eliquid at the flash point, and our goal is to hover around this temperature as the flash point of VG is the higher than both PG and nicotine. However, with VG, at the boiling point(290C), carcinogenic acrolein is produced. This fact should be considered with vapers using rebuildable atomizers reaching high temperatures vaporizing high-VG eliquids. Please be wary of your operating temperatures

I take it to mean that liquid VG begins vaporizing at 176C, and boils at 290C.
Boiling VG is bad due to breakdown and the toxins created.
Running too hot of a coil with high VG juice can, in theory, produce these toxins.
