The bone triptych

I've mounted and framed the three panels of my Bone Triptych, which means I've glued them onto a board and put it in a frame so I can hang the whole thing on my wall, and I've finally gotten around to taking some photos.  




I really enjoyed doing this set of three related images.  This is something I haven't done before, but it's certainly something I would do again in the future.

Time for some colour

The thing about paper sculpture is that it looks totally different when it's painted.  Paint usually emphasizes the sculpture's contours, though it can sometimes obscure some of the details.  The kind of sculpture I make is intended to be painted, and really needs paint in order to work.

This is what my bone sculpture looks like now it's painted:






With bone, I think the secret to getting a satisfactory colour is using many thin layers of paint.  I use acrylic paints, which tend to be fairly flat and don't have the kind of depth that oil paints have.  Acrylic paints are cheap and convenient, but creating a painted surface with good depth and complexity using acrylics requires a bit of work.  This panel with the cross section of a femur has up to seven layers of paint in places.


Panel one


That texture you can see there underneath the femur is done with paint, just to make the panel a bit more interesting.  I've got a tube of Payne's Grey that's kind of old and claggy and it makes some great impasto effects, of which this is an example.

The other two panels use much the same process of layered paint, with some red to highlight the Haversian canals which carry nerves and blood vessels in real bone.

Osteons, again

Like the last post, this one is about osteons.  Actually they're the same osteons I posted last time, but with a greater level of magnification.  The point is that we're looking at the same thing, at successively higher levels of magnification.

They don't look a lot like bone right now, but that's largely because they're blue.  The first layer of paint is blue because I find using a blue undercoat helps to create a satisfactory creamy bone colour.  That'll be the next stage in the project.



All three panels with their first layer of paint.



Close up of panel number three, which I hadn't started on last time I posted.


As I said earlier, I'm interested in the shapes of osteons that you can see in a piece of bone under a scanning electron microscope.  They look almost abstract and are highly textured.  Under very high magnification, osteons are made up of concentric rings of bone tissue, full of small holes and little channels, which is what I've depicted in panels two and three.  Here's a photo of the real thing for comparison:



Picture from Dartmouth


Panel two was done freehand, but since panel three is a magnified version of part of panel two I drew the shapes on a piece of paper, and then sculpted them.






They're made of paper and glue.  It turns out paper is a good medium to portray the concentric rings of an osteon.






This project will rely heavily on colour to bring out the shapes of the bone structure, so my task now is to paint the three panels.

Osteons

Last time I posted I talked about a project I'm doing inspired by what bone looks like under a microscope.




If you recall the first panel has the whole cross section of the femur, slightly magnified, and looks like this:




This second panel is the same thing magnified again, so you can see the circular osteons inside the bone itself.









Panel number three will be the osteons magnified yet again.

Trying some ideas for a new project

When you look at the natural world, and particularly when you look at it under a microscope, it starts to look very abstract.

This image, for example, isn't a piece of contemporary art, it's a cross section of bone seen under a microscope.



Compact bone, from human femur. Bone is made up of two types of tissue: the compact bone forms a shell around the spongy cancellous bone that makes up the marrow space in the centre. Compact bone provides strength and rigidity and is solid in appearance. It is composed of a layered matrix of organic substances and inorganic salts that form around an intricate network of vasculature called Haversian canals.  Credit: Ivor Mason, KCL, Wellcome Images.:

This is the same thing at an even greater magnification.  These round structures with the little holes in the middle are called osteons, which are essentially the building blocks of bone.

I've been playing around with three little panels showing cross sections of a femur at progressively greater levels of magnification.





Panel number one is a cross section showing the compact bone around the outside, and the spongy bone in the center of the femur where the marrow sits.  This piece is made from paper and plaster.







The next one is all paper, and shows the osteons in the compact bone, like that second picture I showed in this post.  It's very much a work in progress at this stage, but hopefully you can get some idea of what it will be like.






I'll talk about the third panel another time, because so far I don't really have anything there to talk about.  What I'd like to achieve is something that captures the abstract look of bone structure under a microscope - something that's all about colour and shape.

Just for fun

No, I haven't abandoned this blog, nor have I stopped making sculpture.   I've just been really,  really slack about posting.  For reasons that aren't entirely clear to me I've been having something of a creative dry spell and I have a largish project that I started on, but which just doesn't seem to be coming together.  Eventually I thought screw it, I'll just play around with some fun things instead.

One result of this was a number of little paper beads made to look like shark vertebrae.




Shark vertebrae have a really cool texture along the side, made from tiny bone septa (ridges).  This is primarily what attracts me to them; the texture is interesting and I wanted to see if I could reproduce it in paper.




For comparison, here are some real shark vertebrae.  The little holes you see in the picture are where the vertebral spines would have attached when the shark was alive.  I included vertebral spines on the ones I made.

Finished hand sculpture

Last time I posted I was very close to finishing the hand sculpture, and in fact I've had these photos and been meaning to post them for a while, but various things got in the way.


  







The late, great Brian Sewell once said of Damien Hirst that "all his ideas were borrowed from things seen as a boy on frequent prowlings in the university’s anatomy museum before, at 19, he left Leeds for London."  Substitute internet for anatomy museum (I should be so lucky), and that's a pretty fair description of my own creative process.

The hand is the focal point of this composition, and since it's highly detailed I've balanced it with a very simple background - just a plain canvas and a thumb print.  There isn't any reason why it's a thumbprint specifically, it's just that the linear nature of a thumbprint ties in nicely with the linear linear blood vessel structures on the hand.  In general, I like to think the composition works fairly well.

I've really enjoyed this relief sculpture, and I have ideas for a couple of others.
