Just as asked. I’m curious as to why some glass is hydrophobic and other glass is hydrophilic.
Some panes are hydrophilic at the top and hydrophobic at the bottom. I dont quite understand that.
Some panes seem exactly the same from the same manufacturer yet display differences in how they take on water.
Interested in some clarification.
i believe it is always some type of contaminate on the glass, outgasing or creeping from the gasket or frame , the screen etc. herewe regularly see hydrophillic glass on the slider not covered with screen while the screen side is very hydrophobic. also a good scrub with bronze wool can reduce the hydrophobia, i assume by removing the film.
In the case today the top half of the pane was hydrophilic while the bottom half (the rained on half) was hydrophobic. I’ll see if I can snap a pic tomorrow.
I saw a video a while back that showed bronze wool on a doodle bug thing on a wet window then water poled, it seemed to work.
