A very detailed 12 step DIY guide on how to make a Hologram. We start by cutting the glass, then making the film, then exposing it to Laser light and finally developing and sealing the finished Hologram. This is DCG (dichromated gelatin) Holography. holocreators.com/
These are the 12 Steps you need to do to create your own real hologram on glass with DCG (dichromated gelatin):
0:00 Introduction
0:13 Step 1 - Checking the glass - To get the perfect Hologram you have to check the orientation of the “parallel-lines-pattern” inside the glass.
1:53 Step 2 - Cutting the glass - With a good cutting technique you will waste less glass in your hologram production.
4:12 Step 3 - Cleaning the glass - An Overview of the best chemicals for glass cleaning and how to detect the correct side for coating the glass.
6:26 Step 4 - Preparing the gelatin - Some proven DCG Hologram recipes and how they are adjusted for different temperatures and laser wavelengths.
9:49 Step 5 - Sensitizing the gelatin - How to add the Ammonium Dichromate to the gelatin mix and properly filter it.
13:08 Step 6 - Coating the glass - Working in a controlled coating environment makes better, cleaner holograms and also keeps you safe.
16:07 Step 7 - Building the exposure setup - Instructions on how to build a holographic recording setup.
18:03 Step 8 - Exposure - Expose your coated plates correctly to get the best holograms.
22:37 Step 9 - Developing - Keeping the many variables under control makes this the most crucial and difficult step in the hologram production.
30:38 Step 10 - Scraping - By removing some of the gelatin the Hologram will be properly framed.
33:49 Step 11 - Sealing - Using Epoxy Resin and gluing a cover plate on the hologram will protect it from moisture and preserve it for many years.
39:44 Step 12 - Grinding - Taking off the sharp edges from the glass will make the Hologram safer and more presentable.
