Loads to tell...

Well, another unforgivable gap in the B&W blog - but I come loaded with excuses, as it's been a somewhat busy period. I shall try and keep the whole thing pared down, as there's much to tell!

1. The exhibition of my stuff down at Artsite has gone really well. Five pieces (small ones) sold - and the promise of a few commissions which is exciting. I'll do more of a breakdown of that later.
2. Lots of press and media - coverage in both local newspapers/mags, and interview with local radio and coverage on the regional bbc online section. This is all really good stuff for establishing a credible artists CV. It's a shame but  also the reality that there are plenty of people who don't simply buy things 'sold as seen'. The back story of the artists and the snob value of an established past counts for as much (if not more) than the simple aspect of whether or not they like the piece. Well, not having studied art at degree level, it makes having a name and recognised reputation all the more important: (go have a looksee - )

Sitting in the gallery has been an interesting experience. Including the private view, I reckon I should have had around 500 people through the doors by the end of the fortnight. Given Artsite's slightly hidden location and maybe less than welcoming exterior, I don't think that's too bad. Certainly I've had plenty of positive feedback from visitors - not to mention a few swapped tips from casting enthusiasts and old pattern makers. Swindon had a large number of foundrymen working in the GWR railway works, so that side of things shouldn't have come as a surprise! Lovely and interested people make enduring the cold sat on reception rewarding. The trouble is with Swindon that interesting/art interested people are a little thin on the ground 10.00am to 4.00pm during the week. I'm going to try and encourage the mangement team there to open in the evenings and weekends instead. That'll make invigivilating easier to organise, as well as hopefully picking up potential visitors who are looking for something to do of an evening (catching the people going to and from the Wyvern too.)

Andy and Bill at Artsite have been brilliant keeping me company and helping man the desk on my college days - and it's also given us an opportunity to talk through some ideas to help PR Artsite a little more. Watch this space!

The exhibition finishes this coming Friday - next things to consider are ideas for my forthcoming trip to the States (erecting a large sculpture over at Gerry Masses Sculpture Trails in July), putting up another exhibition at the Beehive for March (thinking of casting up a load of simple ally scratchblocks for that one) - PLUS staring work on a load of insect inspired pieces for a week's exhibition in the Walcott Chappel in Bath with Gina Dunsford. It promises to be a VERY busy summer...

OK - I'm going to go off now to start posting up a whole load of images to the Finished Works and Exhibitions sections.

Slurry

So, the time has come for us Black & White Casting folks (erm... Toby and I) to push the envelope in our search for more detail in our casting work.  So far, we've been the proverbial* sand-men, packing our formative objects de wax within a silica tomb before applying a generous dollop of hot metal.  However, it can be advantageous in some instances, particularly with work where a high degree of surface texture is required, to use an alternative method - namely ceramic shell casting.

In theory, this is an easy process, you simply make up your wax pattern (in my case a model of a hand), coat it in several layers of slurry, letting each layer dry before applying the next, fire the whole thing (to burn out the wax and to harden the ceramic shell), then tip in your molten metal.

The trick is getting the slurry mix right.

You can buy slurry mix off the shelf (albeit a shelf in a specialist casting shop), but it costs a fortune and we Black & White Casting types "prefer" (ahem) to bit somewhat thrifty when it comes to materials.

Thankfully, Toby had come across a "secret formula" on one of his more recent casting courses, so we used this as our basis for testing.

My first test begain with the creation of a small wax keyring type object.  I then mixed up the soon-to-be-not-very-secret secret formula, which consisted of equal parts of plaster, sand and vermiculite (the latter being old-fashioned loft insulation).  It was a right pain to grind down the lumpy vermiculite into powder, but I sort of managed it and pressed on regardless, adding water to the mix to make the aforementioned (and very aptly named) slurry.

The slurry was the dribbled (for want of a more arty expression) over the wax keyring and put aside to dry.  Once dry (ish) I added a further coat and repeated this process a third time before deciding enough was enough.

I promptly took a couple of months off over Christmas, eat and drank a lot and avoided all things arty (I'm lazy like that).

Having had a long time to dry (in my kitchen) the slurried-keyring had gone rock hard (if a little powdery), so with the dawning of the New Year and a trip over to darkest Wiltshire, the time was nigh to melt out the wax, fire the ceramic shell and get that metal poured.

In short... success.  The ceramic shell survived half an hour with of heat blasting in our bespoke melt out oven/ceramic firing kiln (aka a heat gun and Twinings Tea tin) and didn't even collapse/explode when we poured the molten ali in!  Additionally, the surface of the final keyring was pretty good considering I wasn't THAT careful in it's construction and I hadn't paid too much attention to having a pour cup (to allow a head of metal to press down into the mould) or sprues or anything any sensible caster would have done.

The next step was to refine the process somewhat.  With that in mind I made a better test item (molten wax poured into a metal tin to produce a uniform and smooth shape), modifed with letters stamped into it (for extra detail).  I also purchased high quality vermiculite grinding apparatus (a £12 blender from the Argos sale) and chopped that lumpy crap into proper powder.  Mixing it with sand, plaster and water produced a much  smoother slurry, which acted a lot like that special stuff that flows like a liquid, but is hard when you punch it (look it up on t'Internet if you don't know what I mean).

My final act before close of play was to slurry-ify (technical term) the new wax pattern mentioned above.  With luck, when we return to "the Shack" I will be greeted with a strong, solid ceramic shell which I can continue to build up and (eventually) pour molten metal into!

See you next time.

Exhibition upcoming!

I've posted this over in the Exhibitions section - but thought it worth repeating here (I'm that vain!) A big thanks to Andy Preston for putting the poster together for me.

Dates will be from the 1st to the 18th of Feb 2011 - private view on the evening of the 5th.

Winter is upon us

The first frosts have arrived, and therefore working in the Shack becomes a bit more... 'Shackleton' like. Although the thin insulation we glued on last year has stopped the worst excesses of the condensation, we still get the odd drip - and in really cold weather, its like being in an ice grotto, complete with stalagtites!

I've several projects which need to be got on with - Aluminium Overcast #3 (which I'm hoping will have a home over at ASI, the people who strip down old airframes - www.airsalvage.co.uk ), a piece I've entitled 'Square Pegs in Round Holes, plus I want to make some 'optical moulds' for glass blowers. I spent a fantastic weekend over with my old friends Andy and Becky Potter ( www.pottermorganglass.com ), being given a brief introduction into the art of glass blowing. I had a fantastic time - enjoyed every minute of it, and have come away feeling very inspired. If is wasn't for the fact that I'm nursing a bout of man flu, I'd be cracking on today.

I spent last weekend up at the shack starting prep work for Overcast #3 and having a general tidy up. It has to be said that the shack is *somewhat* chaotic at the best of times - but it felt good making some space and tidying things into some sort of order.

Ok - catch you all soon.
