tests with carved drawings

As I've been getting more and more enthused about tree-branch drawings on my hand-built pieces (as mentioned in this post) I've been bringing this interest to some functional-ware as well... and testing out oxides and glazes. 
Inspired by the mid-fire results I'm seeing on my 'study day' with Shane Kent (where all our work is fired to cone 6) I'm also considering transitioning to cone 6 for all my functional-ware.
Small test pieces (or sake cups) with carved drawing inlayed with a copper carbonate and iron oxide slip and glazed with a translucent satin glaze with lithium carbonate in it. Cone 6 fired.

Two (each side) as above contrasting with the middle one which has the same oxide slip but a satin glaze without lithium carbonate was used, and it was fired to cone 9. The colour result on the middle one is less interesting in my opinion.

making whorls

Something other than pots! Last year I was approached by the lovely Rebecca of Needle & Spindle about the possibility of making some ceramic spindle whorls. Spindle whorls?  These intriguing little objects are something straight out of ancient history - they were/are used for spinning yarn. Rebecca is an amazing spinner and knitter with a keen interest in ancient technologies (check out this blog entry of her's to get the picture). 

I didn't know a thing about spindle whorls when Rebecca approached me about this but a few google searches (specifically on viking whorls, at Rebecca's direction) gave me the picture and I set to making some. They were a pleasure to make and it was a delight to be part of what seemed like a project from another era. 

Rebecca is a generous and eloquent blogger and she wrote a couple of blog post about that batch of whorls, and took some lovely images - check them out here and here. I especially loved the second post in which she details how she took the whorls bush camping and fashioned a shaft out of bracken and proceeded to spin her yarn and then dye it with leaves, all while camping! Now that's true low-tech ingenuity. 

This week I've been making a new batch of whorls because there were a few things I think I didn't get right the first time ... so I thought I'd share the process.

First I form the basic shape, flattening small balls of clay by pinching

Making the hole. This is the part I felt I didn't get right last time... I waited until the discs were leather hard and opened up a hole with a drill-bit - the result was holes that were not as smooth as I would like and probably not big enough for the shaft to fit in some cases. This time I made the hole with a pencil in soft clay and worked on creating a smooth and tapering shape that will hopefully be more practical fitting a shaft to.

At leather hard stage I smoothed the surface a little, ready for carving the designs.

The freshly carved designs, inspired by Victorian flora

This shot shows the profile of one of the whorls - I imagine the decorated, slightly concave side of the whorl facing upward when in use, and the extra thickness underneath should help with the spin (I think? or maybe just help with the stable attachment to the shaft).

Rebecca put me on to this book (found in the local library) which gave me some insights into how whorl shapes affect the spinning... because I don't spin myself I'm still not confident my whorls are great for spinning with, but it's been a fun thing to learn about!

This batch isn't finished yet... they will be bisque fired then oxides will be brushed on and rubbed back before firing again. You can see the ones from last year in Rebecca's afore-mentioned blog posts though... and while you're there do check out some of her other posts - they are always a delight!
