Before I begin using the speedball fabric kit wanted to test what the exposure time will be. I will be using the light fixtures I have at home. 

This post will be about how to use the diazo emulsion fluid and how I used the screen to test a sample of it for exposure times.

Here are Photo Emulsion and Sensitizer bottles I showed you came in the kit in my last post.Before I begin using the speedball fabric kit wanted to test what the exposure time will be.

The Photo Emulsion has a paper top I had to remove. I recommend keeping it upright after you open it, the lid does not seem air tight. I opened the Photo Emulsion remover and stored it on its side last night and it ran out everywhere from under the lid.The Photo Emulsion has a paper top I had to remove.

Fill the sensitizer bottle half way with water and shake or stir well. Then add it to the photo emulsion and stir. The kit actually comes with popcycle sticks, they were under the screen so I did no see them when I did the unboxing post.Fill the sensitizer bottle half way with water and shake or stir well.

I taped up a small square on the screen as an area I will put the emulsion for the test.I taped up a small square on the screen as an area I will put the emulsion for the test.
I poured a line of emulsion across the top of the tape box.I poured a line of emulsion across the top of the tape box.
I used the squeegee to cover the area. I did not put photo emulsion of both sides, however, some drips were hanging on the other side so I did smooth out both sides. I was impressed how little emulsion was needed to coat the area. Of the amount you saw I put on above I was able to put some back in the bottle. This bottle will last a while.

If only I had enough photo emulsion remover left….oh well.I used the squeegee to cover the area.

I Exposed the screen using the light fixures we have in basement. You can use any light source, including the sun or regular light bulbs. The directions give some sample exposure times you should use depending on the kind of light you use. I would still recommend experimenting yourself to make sure you get it right. My exposure time tor this method is about 8 minutes. If you are using direct sunlight to expose your Diazo Photo Emulsion it should take about 1 minute. Do a TEST, however, or you will waste your suppliesI Exposed the screen using the light fixures we have in basement. You can use any light source, including the sun or regular light bulbs.

You can see the places where the emulsion was covered there is a ghost image in light green.You can see the places where the emulsion was covered there is a ghost image in light green.
Because I let it expose too long it took longer to rinse out the image. I used a paint brush to remove the excess emulsion. Because I let it expose too long it took longer to rinse out the image. I used a paint brush to remove the excess emulsion.
