The "Glass Finish" on the HRQ16N3BGS quad door refrigerator is different than the traditional stainless or powder coated (painted) steel finishes offered on other models.
What does Glass finish look like?
Think of a stainless steel door covered by a glass sheet. Glass finishes take the best qualities of stainless steel, like its smooth, polished exterior, and removes all the negative elements, like utilitarian sterility, lack of warmth, and its easily-smudged surface.
It's an alternative to the textured or glossy black and white finishes that serve as the only two common alternatives to stainless, which don't necessarily provide the smooth look that many people are looking for in an appliance finish.
