Alternative ways to create a one-way mirror? Answered


I'm creating a video installation with rear-projection. I want the viewer to see his reflection and the projection so I was thinking of half-silvering Mylar or acetate to create a screen. I also thought of mixing aluminum powder with a clear medium and painting it on however, no luck finding that in Canada. 

My only issue with silvering the screen is that it is so large (10x5ft) that I don't know how to go about heating it up when I pour the solution over it. 

Looking for suggestions for other materials as well as solutions to these issues. Thanks!


You could try making your own aluminum powder using tinfoil in a ball mill.

Good for fireworks, bad for reflective properties.

For big areas you can also use tintin foil for windows, it is available as a mirror foil as well.

a simple sheet of glass will give a good reflection and allow back projection - peppers ghost-

For semi silvering try removing the paint on the back of a mirror with pain remover - then score the silver with a sharp blade at regular intervals - this produces a sort of half silvered effect.
