A couple tips on coating with a "puddle pusher"

 The ink helps you see how good your technique is and how much sensitizer will cover a given area well. On the left you can see a dropper in a cup for measuring out the exact amount I would use to coat with real sensitizer.

This week I started getting set up to make some platinum prints again, and this time I want to use a glass coating rod instead of a brush. In the process I learned a couple of things you might find helpful:

1. I love Bostick and Sullivan, but the prices for their glass coating rods are high. Find a glass blowing shop or supply store and they will see you about four feet of rod in almost any size you want, cut to lengths you like, for about five bucks.

2. Practice coating some cheap paper or toss offs using water mixed with food coloring or ink. I used the india ink I set to make glop for carbon printing. The tint will help you see how complete and smooth your coverage will be. This will give you good practice before you start coating with the expensive metals and paper.
