If i understand this sentence right, this mirror is a chrome based mirror with a transmission value of 3%
The problem is, 3% is too strong and in bright illuminated room you didn’t really can read the white words from behind the mirror.
Better a value of 8%!
“In principle, the coating of SGG MIRASTAR can be thermally toughened*, even on the pulley roll side. Chromium mirror glass can therefore be converted to toughened glass, giving it a huge advantage over conventional silvered mirrors!”
