    Coating Glass Plates

    Hello to All,
    Those of you who have read my posts on this Forum know that I have a pair of hands that are just not connected to my Brain. On top of that, all of my glass plate coating must be done in total darkness, with only a relatively cheap IR monocal. I have tryed the traditional pouring of emulsion; glass rod draw downs;and steel Meyer Rod draw downs. All these methods have given me problems, both with the quality of th coating and with making a big mess, as well as wasting good emulsion on the floor.
    Last night I tried,sucsesfully, the method that Denise Ross uses. She has described it in detail somewhere on this forum or on her website www.thelightfarm.com. Basicly, A catheter syringe is used to slowly lay down a coating on a glass plate nestled closely in a glass frame, slightly higher than the glass plate itself.
    This method is the easiest, cleanest method that I have ever tried. I highly recommend it.
    If I can do it, anyone can!
    Cheers,
    Bill

    Bill,

    Can I get a decent film density range for carbon transfer printing from home-made emulsion? Also, I don't want to use glass plates. Do you know
    how well does polyester sheets take emulsion?

    Hi Andrew,
    I am certain that you can get negatives with sufficiant D-max for carbon printing. My most recent emulsions are as black as my sense of humor. As for printing on polyester,IDK. I have no interest. Denise Ross has published on this forum about her sucessful coating on untreated Melanex.

    Andrew, at the GEH emulsion workshop I coated some AZO emulsion on photoformulary's subbed Estar Melinex and it worked great. I haven't shot or developed it yet, but this is a very easy product to work with.

    You might also consider trying Dura-Lar's "prepared" (gel-coated) surface. Might also be called "wet media"??

    That sounds like a great subject for a You Tube video. What size of a plate did you coat?

    I have a prototype glass plate coater that you guys should try sometime. I have coated about 4 plates at one time using it.

    Results are quite good.

    PE,
    By "you guys" to whom are you reffering? I would be happy to try it. But Buffalo,NY, or wherever you are, is a long way from S.B.,CA ! Is this the same coater that your machinist was having trouble with the base bending? I remember, at your workshop 4 years ago, you were explaning the problem . I never heared anything else about it. It was a big chunk of high quality stainless steel.
