    It's a project with long interruptions, because there's always work coming in between that seems to be much more pressing. But last summer there was a holiday period in which Jelle and I could get to work to finally shape the large mirrored griffins. In my last post on this, from more than a year earlier, I said that these two mirrored griffins will probably be cast in concrete. But I got good news from the customer: on closer inspection he preferred sandstone originals to concrete casts. We can proceed to carving them in stone! I decided that this is quite a big project for me alone and that I would like to make it together with Jelle Steendam both the modelling and the carving. With the combination of both our senses of shape and an extra pair of hands, this will become a great piece of sculpture that I am extremely enthusiastic about.

    Not foam but clay

    Making steel frames for the work of griffin in clay and then casting in plaster

    I had already started to enlarge my scale model in hard foam. But the work was not to my liking. I could not get the suppleness that I had in mind and decided to do it differently and thus, I wanted to model the griffin in clay. The first step was a sturdy frame. I drew a contour template from my scale model, enlarged this to the desired scale and sawed it out of a sheet of wood. Then I welded together a steel frame from square profile tube for the griffin. I could roughly model the body of the griffin out of wire mesh and fix it to the frame, and filled with polyurethane foam. I made the wings removable.

    Shield

    Then came the modeling of the shield. The shield is such an intricate movement of parts with all kinds of details that at first it was difficult to read from the small pictures. When we were almost done with all the casts, the client sent us a whole series of razor-sharp photos showing that I had been very close to the original. But there was also new information that we discovered on them which we will certainly incorporate in the reconstruction. I had already spent many hours in photo editing to find out what it once had looked like.

    A colleague noted that he was more likely to use such old photos as a guide to make his own animals than to make an exact copy of them. There is also something to be said for that. But for myself it has been a challenge to reconstruct and approach the level of the old griffins. It has made me a better sculptor. And it is also a very educational project for Jelle. He has a lot more modeling experience than I do and is also better acquainted with making plaster caps. But doing it on this scale is new to him too! So together we learn a lot. Only when we really start carving will we be on familiar territory; we have done that many times before.

    I made a one-sided cap from the shield and with the help of Jelle also a plaster cast. We could use this for further modeling work on the griffin's body.

    The shields are also both different. They both have a family crest on it, one is of Graf Von Klot-Trautvetter with two helmets and two knights with banners and lances and a motto, and the other of Graf Von Bohlen, with five griffins and three helmets and the weapon motto "Cave Gryphem". These family coats of arms alone are extremely laborious pieces, so this is a project we will be spending a lot of weeks on in addition to the time we needed to model it in clay.

    The general shape of the shield I had also modeled n clay and cast in plaster. I did not model that whole family crest, because that is a lot of work that you cannot transfer anyway with the copying saw. I could better carve it directly into the stone, which is much faster once the drawing's transferred onto it. A good example for this is the large family crest with two griffins that I installed in 2013 in sandstone.

    The body of the griffin

    Then came step three: modeling the body, the wings and the tail. This was the point where Jelle could also come into action. Together we shaped the griffin in a number of days of intensive modeling. Clay can naturally dry out and shrink, so it was very nice that we could do this together in a shorter time. The griffin will be 115 cm tall and the shield 122 cms wide, so that was hard work.

    Plaster molds

    But you can't do much with a clay model. When it dries out, it will crack and disintegrate. When wet, it can sag or become damaged. That is why we have used up a gigantic load of plaster to arrive at a plaster model. We were satisfied with the expression of the clay griffin, so that we could proceed to step 3: Placing plaster molds over it.

    First I took off the wings and tail and made separate plaster molds for those. Then we made, in an intensive rhythm of mixing plaster, putting on a thin layer of plaster in color and applying a thicker layer over it, a plaster mold for the belly of the griffin. The last two molds were for the griffin's head. We definedthe seams with strips of metal, in this case cut from a sheet of zinc that I still had. Finally, the two molds for the left and right half of the griffin followed.

    Castings

    After that Jelle and I made casts of each mold part. We had mixed a good load of glass fiber through the plaster, so that the casts could remain thin. Finally, we joined the loose parts together with more plaster, which we smeared over the seams from within. Overall, we now have a hollow griffin of approx 8 cms thick, that we can still handle a bit.

    But the statue was still encased in the plaster molds! That is why we have also been busy for a few days to carve away all the molds from the plaster cast. Fortunately, we had added a little red dye to the inner layer of the plaster molds, allowing us to see when we were getting close to the final surface. We ended up with a bunch of casts, which may not have been perfect according to the views of professional mold makers, but more than sufficient quality for our copying saw and also good enough for a maquette to start sculpting from.

    Mirrored

    This griffin will later on be carved in stone. And just like all those flying buttress figurines of the past years, it is first sawn on the sculpture sawing machine. For this we need a sturdy model that does not depress when a follower disc rests on it. I could've also cut the beast out of foam and covered it with polyester, but with this method we were more flexible with the design. After all, you can easily remove and add clay, and with foam that becomes more difficult.

    But the griffin will become two different griffins, a left version and a right one. They need to be mirrored and that means the front legs, the claws, sit differently with one version than with the other. I thought we could first cut out and sculpt one griffin, and that we will then adjust the plaster legs of the model so that the right claw holds the shield and it rests on the left.

    Ordered some sandstone

    For these two griffins, the two shields, the four wings and the two tails I have now ordered a batch of Obernkirchener sandstone. The quarry informed me that it will take a while to find good blocks of such a large size for the sculptures. But I really wanted this type of stone, although it is very dense and quite difficult to carve. But it is extremely weather resistant and has a beautiful color. Above all, the material is very strong. I had cut a slice of approx 1 cm thick, about 15 x 15 cms wide, and I couldn't break it with my hands. And yet I still have quite a lot of strength in my fingers. This is a perfect property for my purposes, because these beasts will be standing on 1 front leg, and the shield, the wings and tail are not very thick either. This way they can last a few centuries.

  • Two griffins with a large shield

    The next project has taken a very long time to get properly going. More than a year ago I received this request, and only now there is the peace and time to address this well. It is not a simple little project for doing between other things.

    Castle

    Griffins with Shield ancient castle entrance

    This client is working on the restoration of an ancient castle. There were formerly two large griffins at the entrance, each bearing a large shield with the coat of arms of the Count and of his wife.

    The castle needs to be thoroughly restored, Moreover, its main entrance was so severely damaged that only a few pictures remain of how it used to be. The client asked me to reconstruct these two guardians, so he can restore the entire entryway to its former glory.

    This clearly shows that the original was hollow

    Not stone

    On a few old photos can be seen how the damaged griffins are missing legs and heads. Because of this, it's clear to see that the old statues were hollow, so they probably were casts. Given the age of the entrance, dating from around 1880, I expect it wasn't cast in concrete, and probably not ordinary ceramics either, because the material was quite thick. I'd sooner think of a material like Coade Stone or the like.

    Coade stone is a composite of 10% grog, 5-10% crushed flint, 5-10% fine quartz sand, 10% ground glass and 60-70% ball clay from Dorset and Devon. This was then fired for 4 days at 1110 degrees Celsius.
    Coade stone is very resistant to weathering and can, after casting in plaster molds, still be extensively reworked by hand before firing. There is also an interesting video about this material available on YouTube ↑, including the history of the remarkable woman who stood at the cradle of this material, and its rediscovery.

    Commission

    After much research of grainy old photos and making sketches I first made a little clay maquette in plastiline. Then I was about to magnify this in hard foam. From this, the customer would create rubber molds and then make two mirrored casts in, probably in some kind of artificial stone.

    I'd been carving the foam models for some time when I found that my little clay model gave me too little reference. Because I need to make clear four separate front legs and two different shields, and that should all carefully fit together. That's why I retraced my steps and made a larger clay maquette in plastiline clay. The first model was about 30 cms tall, and in this one, just the griffin itself is 62 cms wide. Plastiline is a modeling clay that never hardens and never dries out. It allows me to continue to work and change things without worrying about cracks or fissures. Modeling wax would allow that as well, of course, but in that material detailing is much more difficult and the lighting is hopeless. There is also professional industrial modeling mass, but for the size I want to make, I would need to spend a few thousand euros on clay, so that's not an option.

    What next??

    Once this larger clay maquette is largely to my liking, I'll make the griffin body out of hard PIR foam with two hind legs and the head, two left front legs,  two wings, two right front legs and a tail. There will also be a shieldin which will fit two different center pieces bearing the coats of arms in relief. Once these parts are cast, they need to fit exactly together and form two mirrored griffins. Altogether a challenging job!
