    Gum print, arabic gum question

    Hi,
    I used to buy my gum arabic in small bottle of 60 ml, this is obviously a too small amount if you are printing much, and it's also very expensive for this quantity.

    few questions:

    -is the E 414 arabic gum powder (for fooding) is apropriate for gum print?

    -Is it possible to buy in bigger quantity this kind of ready-to-use solution on a reasonable price ? i saw that :

    but it says is for protection in terms of storage of plates,1:1 dilution, did someone tried this?

    btw i am in Europa,
    Thank you for sharing

    It is possible to buy gum in the powder form. It is not too difficult to make the syrup from that. Much less expensive. I have made it many times that way. Gum solution used in the graphic arts is often less pure.

    Yes, I buy the powder too, but my supplier is in the US. There must be a source closer to you.

    I think gum Arabic is used in food. So you might find it at a food vendor for cheaper. I think it's used as a thickening agent or candy.

    I know gum has different qualities (grades) but I didn't think that the stuff from arts supply was inferior. Well, you learn something every day.

    Here is a link to some interesting (but not neccessarily related to artistic use of the gum) information: http://www.fao.org/docrep/w3735e/w3735e22.htm

    I don't know where you are located in the Union, but here is one supplier: http://www.kremer-pigmente.com/en/index.html

    Food grade powdered gum is the best; it's very pure / free of contamination (dirt, dust and other alien material / compounds), therefore it gives a very clean / clear gum solution - this is what I use myself...

    Thank you for the answers,

    Powder looks like a cheap and good solution, i just didn't want to bother with conservators, I read everywhere that self made gum solution with powder will not last on shelf if you don't add some chemicals in it, so i was thinking it was nice to think to get some ready made solution.

    I am glad to hear that I could use that food gum powder, This would be OK ? here it's called "E 414" : (sorry german):

    where do you get the additives ? if i am correct : Thymol and isopropyl alcohol, I am in Austria, and it's quite hard to find that stuff if you don't know where to search...

    Hi again,

    I preserve my gum solutions with sodium benzoate; I have 3 years old stock that looks like it was mixed yesterday. I use 1g sodium benzoate per 100g of dry powdered gum, which probably is overkill. I'm sure the gum solution would still keep well even if sodium benzoate is cut to 1:5...

    Regards,
    Loris.

    Thanks very much for the good tips,
    I found some Arabic gum in a local store, sodium benzoate is much easier to find and cheap ! it's on the way.
    Strange than they are both used for food...
