    I use Arches Platine on larger prints and COT320 for 8X10s. Would use COT320 for all if I could afford it because the detail is superior. Tried F. Aristico with oxalic acid bath, but it seemed to remove some of the sizing before coating, so didn't get a comparable print.

    Where are you getting Cot320? No one seems to have it except B&S, and they've been out of stock for some time.

    I have a stash of it right now, and B&S is expecting it back in soon, at least the last time I spoke to them they were, which was just a few weeks ago.

    COT320 - Call Leigh Sullivan at B&S. They're suppose to have a shipment middle next month.

    I've used Artistico quite a bit and I always resize it after the oxalic acid bath(5%) with a starch solution of 1 part stayflo starch to 2 parts water.

    BUMP:

    Thought I'd revive this exchange rather than creating a new thread.

    When acidifying paper do I soak one sheet at a time in a tray? Are there any problems caused when soaking multiple sheets together in oxalic acid solution? Also, once the paper has been in for long enough, what do I do next? I assume just drip dry and hang to air dry to completion. Cheers for your help.

    I normally acidify 8 sheets at a time, keeping them moving in the tray, and drip dry. If the sheets end up with a lot of curl I flatten in a dry mount press. A few more details here:

    Cheers Denis, Will try doing a similar amount in one go. Do you shuffle through the stack, moving the top sheet to the bottom for example?

    I don't shuffle the sheets, but I do separate them by lifting each one a bit to allow fresh solution to circulate.
