    Hi Konrad,

    I haven't done carbo or gum, but cyanotype. If you start with just cyanotype, you could make prints for a fraction of the price and gain much valuable experience that can be applied to the more complicated carbo and gum processes. Cyanotypes are actually quite elegant in there own right and you could print over it as part of a tri-color gum.

    If I am reading your list correctly, the paper you selected is only 15% cotton; you should use a paper that is 100% cotton rag or select one that has been proven to work with the process you are using. For cyanotype, I use Arches Aquarelle Bright White water color paper.

    Have fun!

    SadowskyPL,

    Start with Cyanotype, learn how to make negatives (see HybridPhoto and ask there for digital related stuff) then you can use those negatives to make gum prints. Gum is very flexible, by testing you can just find the correct parameter set for printing from Cyanotype negatives. Canson Montval is good for Cyanotypes, it was the first paper I had used. Carbro is a little tricky and I'm not sure if current materials are OK for carbro prints. You can just make carbon prints later, by pouring your own tissue or (hard to you as I figure) purchase ready made tissue from Bostick & Sullivan. That's completely doable. But first train yourself with Cyanotype. It looks simple but you need the discipline to make high quality cyanotypes; it will give you the "modus operandi" useful for many other alt processes, or, if you like; it will tame you and make you ready for more tricky (because of vast amount of parameters) processes like Gum and/or Carbon...

    Keep it simple for the first attempts -> if not you may loose yourself in the details.
    Good luck!
    Loris.

    BTW, 1+2 gum+water or 1+3 gum+water are both fine. But, 1+3 is a little thin to my liking; I personally prefer to use 1+2 gum+water... Put Sodium Benzoate (I use a gram per 100g of gum, much less will be enough but I do that for ease; it's hard to weight sub-gram amounts) or Formalin (1-2ml per liter of gum solution is enough) to preserve the gum solution. If you do not, it will rot in a couple of days and smell horrible!

    You don't need tempera or oil colors (or acrylics); use tube watercolors or dry pigment...

    Best gum paper (especially for starters) is Fabriano Artistico. Unfortunately it's not suitable for Cyanotypes unless you acidify the paper before...

    See Katharine Thayer's (and Hamish Steward's) sites for gum printing... But don't take all info about gum as absolute; with gum many things depends on your particular materials and working style. You have to test and find the right method that works for you. Read as much as possible!

    First do some gum then you'll try gumoil. You can't do nice gumoils without learning gum first. It's a messy process BTW; you spend a lot of paper towels and you get cramps in your hand/fingers while cleaning excess oil paint from the print. I did a couple and decided that I don't like it at all!

    Thymol is fine. But since you need an extra chemical (alcohol) to dissolve it (and that's an extra step too), I don't use it. Also it's more expensive to me where I live. Sodium Benzoate and Formalin can be obtained for a song here in Istanbul...

    New Cyanotype is very good, but you'll have to use best papers -> it's very finicky when it comes to paper choice. A tip: If you get chemical fogging with your paper of preference, add 2 drops of 40% citric acid per ml of coating solution (don't add citric acid to the stock solution!), probably it will cure the problem.
