Firevase - Legit or not ?
Dear Mad Scientists,
My attention was recently drawn to these fire extinguishing vases:
https://www.dezeen.com/2019/02/25/vase-fire-extinguisher/
I have found very little information about them and would think of a hoax.
I dont see how potassium carbonate will help put out a fire...
Comments ?

Dunno, perhaps the crystallisation of a supersaturated solution of K2CO3 is endothermic?

Here's this ...
"Specifically formulated" aqueous potassium carbonate

Thinking this over, imagine a scenario of a hot pan of grease on fire and you throw the vase with the solution and it hits off-center or something
less than ideal. Seems like a potential to make things worse.

As some one in the field, Potassium Carbonate is used in Kitchen suppression systems and Class K portables all so used as antifreeze in Portable
pressurized water extinguishers. Some times Potassium Citrate/ Acetate is used as well
It saponifies the oil surface creating a soap layer as the water evaporates and cools the oil fire.

Where I come from, anything that is designated as a "Fire Extinguisher" has to conform to all kinds of regulations -- including certain labelling
requirements (ie, ugly).
There are plenty of things you could use for putting out a fire. But there are a smaller set of objects that can legally be sold as fire
extinguishers. This aint one of them.

Thanks a lot for all your answers: I learned something so that's a good day.
I thought they said carbonate instead of bicarbonate. At least that now makes sense.
