    I have used the Arm and Hammer super washing soda in my paper developers with no problem that I noticed. You can also use dye fixative from an art store.

    I went to the NIH and found the name of the product and it was listed as containing 99.8% to 100% sodium carbonate.
    I looked up the product's MSDS and it says the only ingredient is sodium carbonate. In fact it is listed as CAS no. 000497-19-8, which is anhydrous sodium carbonate.

    NIH website page: http://householdproducts.nlm.nih.gov...nds&id=1031009
    Product MSDS: http://whatsinproducts.com/msds.php?brandId=11203

    Either somebody's playing fast and loose with the labeling or some website has the wrong information.

    will the anhydrous absorb water from the air and turn into the monohydrate?
    Yes it will absorb water from the air so store it in a tightly sealed jar. I have found that canning (mason) jars work very well for storing chemicals. They are readily available, cheap and have a nice wide mouth.

    thanks, I think I'll try that

    even though I have plenty of A&H sodium carbonate right now, it sounds like a good way to make it without running out to one of the few stores that have it

    Oh man, that's awesome! I don't care what you put in that developer, just that you got something that worked. Very cool, master Bob.

    Thanks Thomas

    This is part of a new series that I am doing called Big Head Pin Head. A series of diptychs that have friends pose on the same day and I put them into the matts together.


    .. this image is an out ( different from the main shot) where I was just trying something to see how it would work.. I was trying to have the head float in the air with little information around it but the cloth (blue and the background Blue} show too much detail.
    I am looking for subjects for this project as they come to Toronto to visit.

    I have Dinesh (pin head) and Monty M (big head) slated and as well a few others here on APUG..

    I am thinking that if I come to Michigan for Photostock I will certainly be asking you to pose... You could be the big head,, and Bill S could be the pin head... If it dosen't happen this year we will touch base sometime.

    If you are going to ask your "friends" to pose, how are you planning on doing a diptych?
