Hi
I have finally found a Danish dealer of a two-way mirror, but I am uncertain to whether mirror is suitable for a MagicMirror Project. ![alt text](!

@mortenbirkelund

here is another mirror project
https://glancr.de/development/test-spionspiegel-fuer-smart-mirrors/

This developer s has tested different mirrors with different transmissions.
The test description is very detailed.

German:
Der Spionspiegel vom Glaser mit etwa 12% Transmission sowie der Chromspiegel mit 8% lieferten einwandfreie Ergebnisse

English:
The mirror from a glas manufacturer with 12% transmission and the chrome mirror with 8% delivered the best results.

You haven’t more details or datasheets of this mirror?

@mortenbirkelund

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!”
