Bartovation Diffraction Grating Sheet 13,500 Lines/in [One 6" x 5ft Roll]

This diffraction grating sheeting is amazing! 🤩 it adds such a cool holographic effect to fuse/peeler bead creations! This tube comes with a lot of it which is great for using fuse/peeler beads because you can roll it out and cut it to size using only what you need as you go! The ONLY difficulty is being able to tell which side needs to face down when ironing. There is a shiny and matte side (sort of) and if you mess up which side works just flip it over and try again. Otherwise it works well and looks great! 5 stars!

Works on perler beads. I used this on mini melty beads instead of using parchment paper for the melt. Key is to leave on the diffraction sheet till the perler is cool. I added a photo of what it looks like when its hitting the light vs no light.

We’ve used this over a camera lens, projector, and an lcd light cube for some stellar effects.

Love this for my suncatchers.

The roll is smaller than I expected. The picture makes it look bigger than it is and it’s not. I think it’s a little overpriced. I was trying to use these as a “hack” since it’s all over TikTok to make holographic fuse beads. As you can see in the pictures, it’s hard to tell the coating is on there under regular lightings but if you use any flashlight, then you can def see the holographics. It doesn’t come with any instructions just a warning on the label to use gloves to avoid any fingerprints on the film but I don’t find it a big deal without using gloves since I’ll be ironing it anyways. Overall, it does work!! Just not as shiny as I wanted it to be without using your flashlights or turn it a certain direction for the lights to hit. Here’s a tip: The right way to use it is by facing the glossy side up and the non glossy side is facing down on top of the beads when you’re ironing it. Results is kinda hard to tell at first but trust the process. If it is just shiny, you’re using the wrong side!

Seems to be the best I’ve seen. I wasted money on others and this one is the real deal. You can tell it was made with high precision equipment.

The product is great, just have to use the correct side for chocolate I'm order for it to work. Helpful hint. The side you want to touch the chocolate when it's cooling is the brighter more colorful side. Don't rely on the squeeze test as this film is VERY delicate. I advise wearing gloves when handling the film. Your finger prints will imprint into the film and will transfer onto the chocolates. Also the holo effect on the bottom is very heat sensitive so your hands will destry the effect, keep that in mind when displaying the effect on the chocolate. Other than those things to look out for the film is GREAT!!! WIll be purchasing again soon and frequently

I wasn’t sure how well this was going to perform, but blew all my expectations out of the water. Bought a roll to cut into multiple sheets and so far it’s done everything I hoped it would.

This is a single sheet of thin plastic, with the surface on one side to diffuse light. If you temper chocolate correctly for phase 2 crystal structure (89f for milk chocolate), it will retain this diffraction matrix after it sets! Impress your friends with your crazy cocowizard powers! Make some inclusive and representative sweets for your sweet! One roll, 6" wide and 5' long. Some listings are for individual sheets, this is a tube with a roll. None of my tables are that long, though
