Citrato férrico de amonio verde 15% - Química de cianotipo Hoogwaardige

Product arrived on time and in the quality demanded, I recommend

Erg bijzonder materiaal, ben aan het experimenteren en heb goede hoop op bijzondere afdrukken

The chemical (Ferric Ammonium Citrate Green) works fine, but it seems to be finer ground than other batches I have bought from other places. It becomes airborne and therefore it is important to wear a dust mask. This was not the case with the same chemicals I have purchased elsewhere. I also wish the powder came in a light-proof plastic jar - the ziplock packages are hard to deal with. But overall the product is good and I am happy to be able to get the supplies I need at a reasonable price.

I would like to get a paper that tells me How to mix the excact solution. How much water to how much powder of each solution.

Produit conforme à la description. Parfait.
