Cyanotypes in negative and positive

manutex panel

It’s surprising where ideas come from. The inspiration for this piece came from the bottom of a pot – no, not that sort of a pot ! It was a smear of manutex (sodium alginate thickener) that had dried out while it was waiting to be washed, creating lovely frost-like patterns. So, taking that idea, I spread a thin layer of manutex on to a transparency and left it to dry.

I then scanned it and cropped out the middle panel, played about with it to increase the contrast and bring out the details, and ended up with this.

Next I split the image into 9 panels and printed each one on to an A3 transparency film. Now, I’ve always liked playing around with the positive versus negative versions of images so I thought I would convert my manutex scan into negatives and print those also on to A3 transparency film. So, I had two sets – 9 negatives and 9 positives – but couldn’t decide which ones to use for my cyanotype panels and ended up printing the lot on to treated cotton sateen. This fabric has a beautiful, smooth, slightly sheeny surface which absorbs plenty of solution and gives a gorgeous colour.

I played about for a while with different ways of combining my positive and negative cyanotypes and ended up with the version above, simply alternating positives with negatives.

The moral of this is – always look at the bottom of the pot before you wash it up 🙂 .

    Thank you for sharing this. I too have a scan of a piece of dried alginate that I took several years ago but sadly still remains in my take it further pile!!

    I’m curious to find out what blog system you are
    using? I’m experiencing some minor security problems with my latest website and I’d like to find something more safeguarded.
    Do you have any recommendations?
