I noticed many conspiracy theorists for this product... so I'll say: yes this is glass. I tried to scratch it with a very sharp heavy duty knife... it's not plastic!Also, it doesn't just shoot rainbows. You need to have a valid setup... so no, you can't use the sun on a cloudy day (diffuse light) or in a room with more than 1 light source.With a very bright flashlight it's very easy... just rotate the prism until you see the spectrum. The photo I included is a high CRI light source, so the spectrum was fairly smooth and complete.Mine had a broken corner when it arrived. I'm not going to return it, it's almost not noticeable at all.
Thank you for your feedback

5.0 out of 5 stars Everything under the sun is in tune....
Reviewed in the United States on September 3, 2017
I had no specific use for a prism other than sheer curiosity after finding the one I had 25-30 years ago as a kid. It was acrylic and a bit dulled up, like what happens to car headlights. This came in the mail promptly. It IS solid glass and is much more solid. I was using a small AA Maglite to try to get a spectrum Dark Side of the Moon style and what I got was... ok. The next day, I held it in the direct sunlight of a window and it gave off a deep, brilliant spectrum. The colors were enhanced beautifully from the red to the indigo and violet. I held it side by side with my old acrylic one and the glass prism definitely worked much nicer. I imagine that being glass, it would scratch or break easily, so it does come in a padded storage box with a soft liner. Glad I purchased it. Pretty cool conversation piece. Supposedly, a right angle prism works nicely too and I may jump on one too.
