Hello every one,
Good day to you all,
I have a big problem and I need help, I have been using Kodak DK-50 for a while now and I can't get any new supplies from it, I tried to get some from outside Egypt and the airport customs in Egypt blocked it from entering the country, right now I can't work and me and my family depend on my work.
I work as I.T technician in Suez University, Egypt, and my second job in Flexo plates and I need large films for that, I have absolutely no knowledge about chemicals.
I need someone to explain to me how to prepare Kodak DK-50.
As the attached photo I can prepare the Kodak DK-50 & Kodak Replenisher DK-50R, the problem as you can see in the subject title "Sodium Metaborate"
I found the below page here, but can't understand it well
https://www.largeformatphotography.info/forum/showthread.php?101161-Borax-(sodium-tetraborate)-SUBSTITUTE-for-sodium-metaborate
From user IanG
10g Sodium Metaborate can be substituted by 7g Borax (sodium Tetraborate) and 1.5g Sodium, that's the recommendation from Kodak in a Datebook for DK50
If you want a more accurate substitution then:
10% Solution Sodium Metaborate
14.5 grams Sodium hydroxide
69 grams Borax (Tetraborate)
Water to make 1 liter.
Some books have an incorrect substitution, Kodalk is Sodium Metaborate (Octahydrate) which is why the total weight of Borax & Hydroxide is slightly less than the equivalent amount of Kodalk.
But I still don't understand how to prepare sodium metaborate alternative
I prepare 1 liter of Kodak DK-50 & Kodak Replenisher DK-50R
So I want the simple way and quantity to prepare sodium metaborate alternative for 1 liter of DK-50 & Kodak Replenisher DK-50R.
Thank you every one, sorry for my bad English
