he spiral I’ve been chipping away at between other exciting works here at Dreamspace gallery and workshops www.dreamspace.nz is now pretty much like shiny aged bronze…a product I’ve tested from Peter Fell Ltd in Auckland, called C2 hardener and sealer for concrete, seems great…not a paint but a penetrating lithium silicate product which apparently replaces the calcium silicate in the concrete or plaster, making it denser harder and more polishable. ..
Just spent most of today doing this, in between visitors… overnight setting but still nice and soft to carve… in a twist of the unfolding it’s now not for the bronze ‘sunwheel’ – clients want a smaller one for that… will buy this one as well for a different site… with whatever feature I come up with… including carving…so I went for a celtic knot plus some branch hints and on one side a medallion probably to have a celtic knot in it too…
Note the tungsten scraper and also the steel ruler which scraped at an angle around the spiral helped true up the curve.. on a boat hull this is I believe called ‘fairing’ the lines. Also for carving the knotwork I found it helpful to paint primer on first so it is easier to draw and see to cut to the lines… More work needed but at least main carving done while plaster is softer. Tomorrow it will be harder. ..but still ok to scrape with tungsten blades.
Always a mental obstacle to starting the next stage… transition to a different mode feels like a big job. But plastering is actually quite quick… the thing is to begin!
Note the ropes steadying and supporting the sculpture while it sets. Also the screwed wood pieces holding the twisted 10 mm rebar main armature pieces bent at right angles at the floor.
