Very intersting demonstration. Thank you very much for this detailed demo. I have two questions : Q1- what is the % of the Nitric Acid in your small bottle with yellow label ? In Europe we cannot find pure HNO3 but a 53% dilution. In fact we should doubble the number of drops if I am right, to follow your indications. Can you help to clarify. HNO3 can also be found in 98% purity and is called smoking Nitric Acid. Not sure which one you use. Q2- Have you an alternative to laser print to report on stone as the laser has a visible rasterisation that I do not like very much ? Onec again this tutorial is one of the best I found on KZbin. I will continue to follow you.

We are using a 68-70% nitric solution. I get it from the Faculty of Science supplier on my university campus. The manufacturer is Fisher Scientific Canada. As for the laser print, the halftones which I think you are identifying (and don't like) *can* be mitigated or eliminated in a couple of potential ways. First, if you have access to a software programme and/or RIP, you can control and customize the output. Alternately, you can produce your image as an inkjet print, using a much finer resolution, and then photo-copy it. This will convert it fully to b&w, and preserve the dither to an extent. This process will also up the contrast, so that's a factor to keep in mind. Good luck!

I've been interested in lithography for awhile now but it's really hard to find a lithographic stone. The ones I'm finding are all used and battered and still really expensive. Does anybody still make them?

Hi, buying "new" litho stones is almost unheard of. I suggest you find a printmaking studio or university art programme in your area to connect with since they may have leads on good used stones or ones that someone is giving away. They might even be able to help you get an old stone nice and flat and printable again! Good luck.
