It'll be after November,so everyone who can, will be throwing on their life vests, jumping in the sea and paddling like Cubans but in the other direction.
Fuck me dead and bury me pregnant!

Stunning work! Please show us more progress pictures if you can!

Have I said WOW already? I'm a big fan of this topic already...

Ok, here's a couple more.
This is still a test sample, we are making this to work through the issues involved in the laminating process. Issues like, how the hell do you glue things this big together without getting air bubbles and crap between the layers.
This is 10 sheets of glass with the contour lines compressed to form the image. So it has some depth but nowhere near the final piece which will be 10 times thicker.
Something most people don't realise is that glass isn't very easy to see through when you stack it all together, you get multiple reflections and clouding and the more layers the denser it becomes. You eventually can't see through it at all.
However, when properly 'glued' together the block of 100 sheets will become pretty much optically clear. You will be able to read a newspaper through it.

Fantastic project. Very interested to see the process and results!

This was a test to confirm the amount of detail we wanted to put into it, we needed to do a large enough section so that we could see if the back and front faces worked together. It would be no good if the hair on the back of his head overpowered the detail of his face. I think we have got the balance right.
As I mentioned earlier, sheets of glass stacked together become too dense to see through, but once laminated it becomes optically clear.
You can see that here, the first image is just dry sheets of glass with all the detail but not glued.
The second is the same sheets glued together.
The third is with light from underneath.

Some would call it an "exceptional art object", others call it "just a test"...

Thanks Cotty, I know what you mean.
But now that it has answered the questions it's just a 90 kilo lump we have to put somewhere out of the way. -
Seems a little morbid!

yikes, so how much will the full project weigh?!
-
I think I mentioned that in my original post. ~3000kg each. We are adjusting the calculations all the time as we refine things. The special air bed transporter is limited to 7 metric tons. So we need the two blocks and their support structures to come in at less than that. It's going to be close.

insane just freaking insane !
-
BRAVO!
-
The job has been tied up in rather uninteresting testing and jig construction lately so no interesting photo ops. But I figured this little vid might be of interest and give a bit of an idea of how dynamic the sculptures will be.
-
I'm surprised how good you can see through the whole glass block...
-
Looks incredible! Is the green color a choice or is that always the result with a huge block of glass.

Yes it is remarkable, when correctly laminated the optical quality is almost perfect.

All clear glass has a colour, usually this greenish tint, sometimes it is a little bluer, but it's not normally noticeable when looked through. If you look at the edge of a piece of glass you will see the colour better.
You can get several varieties of "white" glass, Saphire, Starfire, Low iron etc. They are expensive and not what we wanted in this case. We had to make sure we were able to get all the glass we needed from one batch so the colour was uniform. I made a sculpture many years back that ended up with a blue stripe through it. -
A bit of an update, this is what about 1/3 of a block looks like. This is just a dry stack of glass so it is too dense to see deeper than a few layers.
-
Have done lots of glasswork, but this is definitely a masterwork!
Couple of questions...
How are you actually attaining the contours?
I know you mentioned acid shading, are you using hydroflouric acid?
Are you laminating with a UV glue, or a film laminate?
Sending links to all my glass buddies, thanks for sharing, this is a fantastic project. -
Those are some very knowledgeable questions Dale.
Do you mean, how am I getting the data for the contours or how am I putting the contours on the glass?
I have 3d scanned two posed models to get very detailed meshes which I have sliced vertically at .5mm . Then I laser engrave those contours onto the appropriate layers.
We abandoned the acid shading, it confused the image. But no, it wasn't Hydrofluric. That stuff is just too complex to work with on such a large scale. I've used it a great deal over the years, seen the results of a tiny splash, a leaky respirator etc and didn't want to get involved with buckets of it for this job. We used the simpler version, Armour Etch, still dangerous, but thankfully not needed now.
The laminating process is quite involved and isn't just one or the other. We have had to develop a unique combination of techniques and glues specifically for this job. UV would be no good as the Sculptures will be outside in a fairly harsh environment. The expansion and contraction of such a large block would tend to tear the layers part, the glue wouldn't fail but the glass would.
So I've had to use a system that allows the whole block to flex, breath and enjoy the snow and sun on its face. It has been something of a challenge.
