mikewhi said:OK, I mixed my first batch of ANSCO 130 this evening using the old stock of chemicals I have on hand. The stock came out dark ice tea color, or the color of coffee those heathens in the mid-west brew, not the stout proper brew that we have perfected here in Seattle.
I will be printing with it soon, starting out at 1:3 (recommended by folks here) and AZO Gr2 and Gr3. I'll try some other papers, too, like the JandC Museum paper.
I noticed that at least one of the ingredients called for a fraction of a gram (like 2.2gr or 5.5gr). My scales only measure in 1 gram increments. How important is it that I get that .2 or .5 amount correct (Metol called for 2.2gr I believe)? I estimated but I'm sure I was off .2 or .4 gr.
Do I need a scale that measures fractions of a gram? If so, can someone recommend one? Do you know how I would calibrate it or verify it's accuracy if I bought it used?
Thanks.

Robert Hall said:I wouldnt worry too much about .2 grams, but if you do you can put 22grams in 100 ml of distilled water and use 10ml of it. (I would just add 2 grams and be done with it.)
Just make sure it's disloved before moving on.
If you want a nice scale see:

I've used this one for a long time. Works great.
To verify your scale, weight something you already know the weight of, such as a 500gm counter balance.

Hopefully your solution of Ansco 130 will work well for you. I would not be concerned about the small measurement differences, but the color of the solution is of some concern. My current Ansco 130 solution was mixed with fresh glycin and is very clear, perhaps with a hint of yellow. A previous solution that I mixed with old glycin was the color of dark coffee, and gave unacceptable results.
Of all of the commonly used reducers glycin appears to have the shortest shelf life of any. Compare to Amidol, for example, which appears to have an almost indefinite shelf life. Michael Smith's current stock of Amidol, for exmaple, is almost 100 years old according to one of his messages on the AZO forum. In my experience a number of other reducers, including pyrocatechin, pyrogallol, and phenidone also have very long shelf lives.

juan said:I know it still works because I recently tested a film developer made solely of glycin and TEA - worked just fine (although very slow and too expensive.)
