Denise,

Thanks, I wonŽt give up. No way. I just have to keep it simple. I had the idea of bying a heated car windscreen in Holland. A rear window I mean, flat, straight. One of my funny ideas.
I first try to sort out at which temperature the emulsion starts to set, then IŽll try to coat just above that temperature.
Apart from your video tutorial in a movie about George Eastman, you could very well see how the emulsion was of a thickish nature and was applied by the same puddle pusher technique a you showed.
I know there are other ways too, but IŽll keep that for anotherday.
Have a good time,

Henk
