The AN glass goes on top only. The rings form between the base side of the neg and the smooth glass.
You maybe can fabracate a top glass carrier with no glass on the bottom. Lots of enlargers are made this way. I just installed a AN glass from a slide mount into the top of my 35mm Omega carrier. I left the bottom open.

Thank you Ronald.
The anti newton glass is on top , you can use clear glass on bottom or as Roman says you can use a regular bottom carrier and glass on top.
I think as the enlarger heats up the negative bows towards the heat. therefore glass on top is good.
Personally I prefer glass on top AN and Regular bottom
As well and I find this to be quite critical and will pass these gems of info free of charge to this community. Usually its$9.99 video at Kmart
when using glass carriers for mf printing or 35mm I have a strick set up proceedure as follows.
1. approx center the negative in glass carrier, emulsion down
2. raise the enlarger height to the correct printing height
3.In my case make sure proper condensor placement is in.
4. put in the proper lens
5. place the easal into position and take neg carrier out of enlarger
6. turn on enlarger and position the easel dead center to the circle of light
7. put glass carrier set up back into the enlarger.
very important ladies and gents.
8. make sure image is centered into the easal blades, if not move the NEGATIVE not the easel.
9. when you are happy that the easel , lens , negative, condensors, and light are in a vertical path.(tape the negative to the bottom glass)
10.Important step> I use black masking tape on the underside of the glass carrier to mask out the raw light going around the mf negative(some enlargers have swing in blades for this purpose)
I use a light table for set up, I have qtips handy , canned air, lens brush , anti static cloth , negative cleaner.
Keeping the humidity down is good to control dust.
If I am not sure of the enlarger alignment I will check after everything is sized and correct if needed and then start printing.
Sorry for the long post but I think the above is critical for edge to edge sharpness and this is the technique I use.
