Smile Efflorescence

I am working on a video about efflorescence. I have just about completed it. Just wondering if anyone has anything they feel I should add that is important?

If there is time in the vid maybe talk/show about a problem that looks like efflorescence but is not. Such as frosting

Default Frosting

Sorry for my ignorance but what is frosting? We may refer to it as something else here.

On another note the term "salt" is a generic term that relates to an ionic compound resulting from neutralization. In the case of Zinc it is as a result of the anodic sacrifice.

In the case of efflorescence the loss of water causes crystallization from a hydrated or solvated salt. So it is not the moisture that causes the efflorescence it is the drying out of the water leaving the ionic compound found in the minerals of the masonry surface. The moisture is like the vehicle to draw these compounds to the surface.

I am finding the more I research this subject the deeper it gets. I can't afford to go that deep with my students as I will lose them. In time I may try and find a simple way of explaining this.

So it seems to me that version two will be coming up soon!
