"tube" results

-
After the pieces had plenty of time to cure or hydrate so the concrete had the chance to harden nicely, here they are:

building up layers of dark or white mix


making latex stamps and impress them into wet mix










texture when hardened, stained with rust

samples combined with a looped wire rope, explored different angles for different 
perception or meaning and different surface treatments like polishing or sanding down 
to the prior layer


I'm pleased with the outcome and it turns out that the formula I used offered me a lot of the textural properties as I worked. I got the surface I wanted, just like that, after trying so hard making moulds for impressions etc. 

The rather viscous white mix feels like porcelain slip and also looks a bit like porcelain in the hardened stage. I wrote about the versatility of concrete before but now it becomes even more apparent. I can almost mimic a ceramic piece, treating the surface by polishing or sanding. The rusty stain comes from ferric chloride that I have been using for etching copper pieces. The resolved copper will hopefully give some greenish tinges, similar to when I used copper carbonate, iron oxide or manganese powder on my ceramic pieces.

more glazing trials on discs

Eventually, I would like to achieve textured tiles that I can use to make flexible latex moulds for impressions on future concrete forms. I did further experiments in clay and glaze to bring me nearer to the desired outcome.  Prior to the actual clay work, some drawing exercises: Creating texture with string: sample discs: Glazed after the first firing Results second firing: I used parchment glaze in green and violet, a simple white glaze, red glaze in varying thicknesses and for the dark parts it's manganese that went under the glazes. I like the outcomes as such but think I'm not where i want to be yet in terms of texture. The impressions with string are a start and I will try a mould sample from the disc top left corner to get the reverse effect for a squiggly texture. The sample bottom left looks very intriguing and organic, especially on the right half but feels far too pointy and unpleasant to the touch. All in all, I like how the manganese reacts with the glazes and give

Final Reflective thoughts

Sandra Holle HOL14245918 August 2021 Reflection and evaluation of my MA / professional practice course:   When I first started a Level 3 course at Hull College school of art and design in 2014, I only wanted professional advice on my painting and to improve my technique. Since then, painting is what I have done the least. What, however, emerged over time, was an understanding of why I do what I do and why it always seems to develop towards a certain direction. During all the projects that I did, there was always a sense of distress, muted colours, imperfections and organic-ness to my work that I have grown fond of. That’s me.   I moved from oils to drawing to school workshops to animation and model making to knitting with upcycled PET to clay and finally seem to have settled with sculpture, mainly in concrete but I also don’t mind the occasional piece of copper on my workbench. These 7/8 years gave me such a wide range of skills and I was well able to feed my curiosity about different
