Green Man Mask continued

I've taken the annealed mask out of the kiln and started work on adding more leaves and details. So far I've learnt;

Getting quite far along, still needs a few more hours yet
1) I need to think more about my work flow.
     I didn't really expect this first attempt to go so well, and jumped around the sculpture a little too much. This has left some areas under more stress as some leaves pull on others, and when I start heating sometimes this stress has caused parts further away to snap. There was quite a lot of re-joining and tweaking as I went back over areas, even just as I finished one of the first leaves came away that'll need re attaching.
    This time I went a little slower, as I added each new leaf I took time to make sure it was well joined, then while it was still hot (and the new join a little flexible still) joined it anywhere else it was touching the main structure to ensure it has at least two firm hold points, then re-heated the first joins just to make sure. I think 'just to make sure' should be the motto for doing this sort of work!

2) Nice work for hot weather.
      I do really need to get more pendants and big marbles made for the next Expo (yes I know it's months away, but foolishly I did book both London and Birmingham which are only separated by a few weeks). It's not too bad until the afternoon when the sun swings around, and the kiln starts getting hotter. This makes a nice change, and as I only need one wheezy old oxycon and the extractor hood on it makes for quite a quite and chilled out working.

3) Tricky to light, ok once lit
      Talking of old oxycons, it can be a bit tricky to get the mini torch to light and stay lit to start with. It might be because it takes quite a while to get all the air out of the oxygen and propane lines, once it has though it seems (mostly) ok so long as I don't have to turn it back off and on again! This is where a stand would be really helpful, if it allowed it to stay lit when needing both hands free.

4) Tidy that workbench
      Actually, I can't really see that happening, I even get around not needing to tidy it when working 104 glass by putting a board over the top of the debris! A separate little work area, with really, really good light would be ideal though, maybe that's a little higher too.

5) More plaster, less filler
      This poor face cast is starting to look like a bit of a burns victim, or something sort of Evil living-dead-doll from an Asian Horror film! The modroc is charring when the surface gets knocked or flakes off, so a thicker plaster/quartz layer might be better. Maybe also use chicken wire for strengthening instead. I mostly used modroc originally because I happened to have a big unused bag, and it makes quite light casts.
Charred and battered cast

6) Stay calm! Make good support underwear and it can be fixed!
      Hard to do when you heat up one area and another goes 'crack,' but that really probably comes down to the initial problems with not making some of the first joins as well as I should have or putting others under too much stress. Having to go back and re attach them has probably made the whole sculpture stronger and better made though. Next time I'll have to think more carefully about the best way of putting down those first leaves that become the scaffold for the rest of the sculpture.

7) Make more leaves
     This uses a huge amount of leaves, which is ok as I wanted to define the shape just in leaves anyway, but I never seem to make enough. When I've looked at Green Man pictures and original church stone sculptures they make most of the face with very few leaves. Sometimes it's one per face area (i.e. one of each cheek, one for the nose) and then stretch them out to make the shape. I wanted these green faces to be more like you might see them, when in a glimpse out of the corner of your eye the overall shape of the branches and leaves in the trees suggest a face, but then when you look it's gone. Or is that just me?

All in all this has been an interesting project, although it's not finished the next questions are 'do I make another in coloured glass,' and 'do I leave clear or sandblast it to a frosted finish?' And if I did frost it, it then leaves another decision, to then leave it as it is or paint it which leaves a nice matt finish? Mind you, as I don't have an airbrush/sandblaster yet it's probably not really a relevant set of questions!

In other news I might only be at Greenwich this Sunday (or not at all, I'm not sure if I can make it yet) so I am hoping to get some more marbles listed into my Etsy shop this week. As usual I'll give a heads up on Facebook to let you know when I start getting them listed.

Plastic and Bullets

I seem to have several projects on the go, the problem often is finding time to finish them or just that last component that will make it work. Embarrassingly, for far too many months gathering dust I have some glass from another artist for a collaboration that have sat in a box in the corner of the workshop/office/studio/storeroom that I seem to live in right now. The problem with that one has been finding two odd bits that will bring it to life, plus some old text books that are buried in the attic. I am sure I will get to it (eventually.)


Crown blank neatly cut out by machine
A newer project that has been rattling around my head for a year or two saw a step closer this week to actually getting out of my head and into the real world. It is going to be a head-dress, or a crown, or something like that - it's still taking shape. I'd could describe it, but I won't, because partly it might spoil the magic of it comeing to life, but mostly because I'm not totally sure how it's going to come together yet.

One key part needed was some old bullet cases, but it's taken until my short New Year break to be able to pop along to a local army surplus store to rummage around for some fired blank shells in various sizes. At the same time I bought some blank tiara/alice bands from a haberdashers which were going to form the base. However once I'd got home I realised they were too thin, too flexiable, and also I'd need to bolt parts onto them at right angles.

Faced with having to cut out a crown shape by hand didn't really fill me with excitement. I was debating between aluminium sheet and acyrlic, both are light, acyrlic was cheaper but I remembered the problems I had last time when cutting through a sheet. I used my trusty electric scrollsaw, very carefully taking my time to saw through so I got a neat straight line. When I finaly got to the end the heat of the blade had just re-welded the plastic together again! So, aluminium it would be.

I was going to order a sheet when on Saturday morning I was setting up at Greenwich and inspiration was setting up a few stalls away in the shape of 'The Shed Laser Co.' who make all sorts of things out of acyrlic! I remember chatting to Sarah who said she could cut anything to order, so I described what I wanted, got a quote, and was sorted!


 Monday afternoon I spent drafting on the PC, then cutting out bits of paper trying to get the shape and sizes right, before emailing Sarah with the design - even down to having the holes so I didn't need to drill them out (and risk cracking the plastic while doing so.) Next Saturday morning I was at Greenwich she gave me the crown base, all neatly cut out! If I'd have done this by hand it wouldn't be anywhere near as neat, I'd have been hot and bothered, broken a few blades, and probably just put off doing it! If you want to do something like this too, and need some plastic 'printed' I know Sarah is in the market most weekends, and you can find 'Theshedlaserco' on facebook too! (I tried to put the link, but for somereason blogger doesn't want to!)

Hopefully there will be more on this head-dress/crown/head-art-installation in forthcoming blogs as i make up some more parts of it.

New Fan, New Aches but No Toxic Gases

Well I finally got the new fan installed on boxing day. The original plan was for a day off (I've heard of those) and go out, but it seems it's business as usual when OH got called to work instead, so I figured I might as well use the time productively.

I was going to get a boxed acoustic fan, to keep down some of the noise, and know they are quite popular with many lampworkers, although I wanted something with a bit more power. I'd almost settled on one when I came across some reviews on a hydroponics forum, for which many of these fans are made. The reviews were good, but many of the mentioned a TD-Silent being the best and most reliable they'd come across. Price-wise they seemed pretty good for the money too, the one I wanted only had a 19db level too, so took a deep breath and placed my order.

I didn't quite expect something that looked like it had fallen off a military jet! I didn't get around to taking a picture, so here's a quite You-Tube link for those considering one! TD-Silent video



 The one I got has a massive 200mm intake and outlet, so the first job was stripping out the old fan, which it turns out might have needed a bit of a clean!


Old fan from the original cooker hood
 I've kept and used the switches from the original unit, it wasn't until the new fan turned up that I found it has two speed so needed more switches to control it. At the same time I took out the lights (which were in the wrong place so never used) in the cooker hood and just about anything that might block the airflow.

Straight up and into the outside world for you Mr nasty toxic carbon monoxide!

From there it was time to seal up the sides of the chimney. Originally I'd intended to use a big 200mm pipe I'd bought for the job, but since the old cooker extractor had a nice chimney that was nearly the same size I figured it would do just as well. A quick trim of some spare aluminium sheet, then a little duct tape to seal any gaps and holes and the job was nearly done. Or so I thought! A joist was in the way so everything came down so I could move the whole canopy over just 3 inches!

Shiny! There really is only one exit, but the mirror inside of the chimney makes it look like three!
After another hour or so of clambering around in dark and dirty, and very uncomfortable, spots to get a small bend of flexible tube attached and sealed, the job was really finished. It's not a very tidy or as neat looking as I'd wanted (I went a bit overboard with the duct tape!) and needs a bit of trunking to hide away the leads. It is quiet though, and a quick test with an incense stick showed even on low power it whisked it away with no problems. On high power I barely even saw the smoke leave the incense stick, it was just gone! Not as quiet as I thought, there is quite a rush of noise from the air moving, however when stepping just a few feet away I could hardly hear it, a huge improvement on the low rumble the old one used to generate.

Needs a bit of a clean, but despite the bodging it has nearly doubled the amount of air this old cooker extractor hood can remove
I'd expected it to take two days to get everything in place, so was pleased to get it done, despite the odd set-back, in a day. However today I've woken up with so many aching muscles and bruises I've got hardly anything done, thus getting chance to sit and blog, so maybe my original schedule was right after all!

I still am not sure if I'll be back to Greenwich between now and new year, I am sure I'll get around to a break sometime in the next few weeks if not! I hope you have all head a great Xmas, and may I be the first to wish you all a happy 2013!

The Harry Pickup method of craft design


Who? I hear you ask, maybe followed by ‘what?’ and then maybe ‘have you really lost your marbles?’ (The answer to the last is yes, there are probably some rolling around under my bench somewhere.)

Do you ever have one of those craft problems where you are missing something to make the ‘thing’ you make? Or it’s gone wrong? Or there is an eyesore on it? Well then it’s time for the Harry Pickup method!

There is a lot of hype around this chap, and maybe it’s more myth than reality, but just after WWII Harry was (supposedly) trying to find a way of getting rid of some nasty caustic waste ash. In desperation he even tried flushing some down the loo, when he noticed it caused an interesting reaction. All the limescale was removed!!! He then took this waste product and turned into something every housewife wanted! Unsure what to call this new product he just took the first three letters from his first and last name…….. Ah! See, you probably have heard of him!!!

So basically I’m talking about taking what you think are negatives and turning them into practical positives, and when things aren’t going to plan I think to myself ‘What would Harry do?’

I’ve been looking into holders to mount marbles in to make walking sticks, and I’ve had a lot of ‘Harry’ moments doing it. I’m still miles away from getting them made, but each stumbling block has helped improve the design. For example I was looking at some nice brass lampholders, and converting them to use as a cup for the marble. However they had an earth terminal fixed to the side; removing it would have left a hole. So instead of thinking how I could remove it, I wondered how I could use it? I could use it to secure a hand-strap! Ideal so it could be put around the wrist to save dropping it, (useful when the top is solid glass!) or even just to hang it up. In the end the holder was too small, but I’ve kept the idea for the hand-strap which I wouldn’t have had if I’d just cursed the useless holder and moved straight on.

On a Steampunk forum a while ago I came across a thread where someone was trying to get rid of some writing enamelled into some old lab glassware (which of course caught my eye!) There were lots of complicated answers, attempts to burn it off then re-annealing it, super-dangerous chemical treatments. My solution was to turn it into a feature of the sculpture he was thinking of making by putting a decorative brass collar around it. Simples!

I see so many links to motivational websites telling us to be positive, all are very good at talking up how to think positive, but I really don’t find many telling you how to turn that into reality. I hope this will give you some ideas to get around that stumbling block by using the stumbling block itself as your leverage. So next time you are stuck, try thinking of Harry, and turn the unwanted into an advantage.
