FOUR FIGURINES

FOUR FIGURINES

Here are 4 figurines that have recently arrived in the studio.  Previous restoration is evident on all of them with losses and discolouration of varying degrees.  First thing I need to do is to get rid of the old gunk! So DCM, soak, rinse, steam cleaned.  You have to be careful cleaning the tiny pieces as the pressure of the steam can cause small fragments to shoot off in any direction.  One way of stopping this is to use a fine metal gauze placed over the piece that needs to be cleaned.

THE LADY ON PEDESTAL

The above lady's head was partially joined to the body.  On further inspection a matchstalk had been lodged into some grey putty in the head hollow.  The bow on the hat has losses and the rim of the bonnet has a slither lost.


Finished figure




THE VIOLIN PLAYER



This elegant violin player has suffered breakages and losses.  The leg looks to be a clean break but the small hand has missing fingers and the violin has lost the carved scroll machine head.  The broken leg was relatively easy to attach using special epoxy which I propped up using sculptors plasticine.

Mould of scroll made of sculptors plasticine ready for silicone, very tiny piece!
Tiny end piece made and attaching to the violin and hand. I also had to
extend the missing finger and thumb that was playing the strings.

COMPLETED FIGURINE




BOY IN BLUE TROUSERS

This one is more problematic in that there are several losses not obvious until I get it out under some good lighting and magnifying specs. Some pieces remain so this will be a good jigsaw! After having cleaned the pieces individually I can see that the discoloured piece beneath the body is not ceramic but some kind of old fill, looks like plaster.  It has been badly repaired and I'm not sure which angle the head will go? There seems to be a loss on his right cheek which may suggest that the hand touched there.  The head was totally askew when it arrived so I have to think about this one.

       

LOSSES
  • Base losses on each side of the feet to base
  • Loss on the join of proper right knee
  • Loss on joint of proper left knee
  • Loss from top of wood stump that joins to the blue trousers (proper right)
  • Large loss on proper left ankle and foot
  • Loss on inside proper right jacket (yellow)
  • Front chip off white blouse and part of the 'v' neck of blouse (front)
  • Chip on basket (dark maroon)
  • Loss underneath proper right arm around to the back of the jacket (pink enamel)
  • Loss to proper right hand which pushes against the pink jacket which has to be created
  • Losses of gold borders in many places
  • Loss of proper left thumb that's holding the basket

FILLS

I mixed up 3 grams of special epoxy, bulked it up with fumed silica and let it rest for half and hour.  I then mixed some Titanium Oxide white into a small amount of epoxy, to achieve the colour of the white body. Blending the white mix gradually into the rest of the mix to get the correct opacity, looking and holding it against the white body and to the daylight.



Fill on the back shoulder propped up with sculpting plasticine.
Below the fill to one side of the base

Next fill at other side base and fills at the knees held at an angle whilst curing
Fill at neck and part of right hand
What was I thinking!! I've been looking at how I put the head on and it's just not right at all.  This is tricky and I have come to the conclusion that I have to dismantle and re-do.  The head and shoulder took a good couple of days to come apart again, right ready to go again ........
OK this looks better!!
I used sculptors plasticine to prop up the head and shoulder so I could see exactly how it might fit into the proper position.  I then used part of the epoxy mix to fill only part of the neck.  The next day it was still soft enough so that if I wasn't happy I would be able to move if necessary.  It was ok, so I left it to cure another day. 


  • A.  Top of the shoulder filled up to where the collar of the jacket is to be created
  • B.  Loss on the top of the cuff
  • C.  Fill of the frill on the blouse
  • D.  Fill where there were chips on the neck



  • E.  Join where the forefinger meets the cheek
  • F.  Cut off piece of pipette to keep the shoulder in position which will be removed
I am now going to allow this to cure, put the rest of the epoxy mix in the freezer and come back to it again to create the collar of the jacket.

Now we've got to get the legs and base back on......  when I took the boy apart again I didn't remove the fills that I had previously done on each side of the base.  so I have to refill the knee joints and the large loss on the proper left foot.

AT LAST DONE!










LADY WITH FLOWER




This lady carrying a basket of flowers looked only to be a clean break at the waist but is actually in three pieces with a slither.   She also looks as though she was holding a flower which are missing and also that her little finger looks as though it was extended these have to be re-modelled.  I also re-modelled a leaf and flower petal that had been missing in her basket.

SPODE JUG

SPODE JUG

This jug is 7.5 inches tall and was stuck very badly with epoxy that had discoloured with age. It is mostly the side and pouring part of the jug that has suffered impact damage, however on inspection part of the lion head on the top part of the handle was missing.  Very pretty design on this one, I'm looking forward to working on it!


Jug de-bonded and steam cleaned


This jug has a pale coloured clay body which has not been fired to a high temperature and was therefore slightly porous so I didn't soak it.  I de-bonded the old epoxy using DCM over five hours in an enclosed container.  The pieces came apart quite easily and I used cotton swabs and de-ionised water to clean off the DCM residue.  Some staining remained on the edges so I used Laponite with 10% hydrogen peroxide (35%).  I put the Laponite/hp mix on the edges and covered in clingfilm for a few hours which worked well



As the ceramic body had not been fired to stoneware it was not suitable to use special epoxy directly onto the surface.  I therefore consolidated the edges by brushing with Paraloid B72 (Acryloid in the USA) 15% in acetone prior to application of the fills.  




This is the jug after I'd done the fills


For the fills I used special epoxy and bulked it up with a mix of fumed silica and marble dust which gave it a similar texture to the ceramic.  I used historic pigments to colour the epoxy to achieve a creamy shade.




The fills here have been taken back to just below the level of the glaze.



Here I have re-touched in the missing design using Golden airbrush colours

AT CITY & GUILDS OF LONDON ART SCHOOL

CONSERVATION PROJECT 2010


This is the Buddha at the Buddist Centre in Kennington, South London.  

This stone carving had been out in all weathers and was in need of some care and attention.

Buddha partially cleaned with steam cleaner

Here you can see clearly where the Bath stone has been cleaned.  
This was done using an industrial steam cleaner, lots of brushing and using
a biocide to get rid of and to prevent algae forming on the stone.


Buddha totally cleaned

Here is the buddha all cleaned to begin the pigmented limewash prior to the gilding work.


Buddha limewashed and partially gilded

 Here we've put on the pigmented limewash and have gilded the head, hand and feet.  
We used a coating of 3 hour gilding size on top of the pigmented limewash to take the gold leaf. 

We didn't gild the cushion or the hair (bumps of knowledge) as historically these are not gilded.



We painted the 'bumps of knowledge' with casein paints which will cross-link with the stone over time.


The unveiling of the Buddha after finishing the project

And here is the finished Buddha, gilded in two shades of gold leaf.  At the unveiling ceremony the original carver of the Buddha came and we threw silk scarfs onto the buddha and said prayers.  It was a lovely project to be involved with.  A hood has been made to protect the gilding from bad weather.

The Cosmati Pavement - Westminster Abbey

One of my summer placements whilst at City and Guilds of London School of Art was at Westminster Abbey, conserving the Cosmati Pavement with my fellow classmates Lianne and Lucy which has now been completed.  Unfortunately, I was not present at the filming of the video as I was rushed into hospital!!  I did however manage to work for four weeks doing the same work as my colleagues.  Lucy now works at Westminster Abbey in the Conservation Department.

Click on the link below to see a video of what we did..........



This tomb intrigued me the most because the turquoise, red and white mosaics
were made of glass and there was no evidence of where it originated. 
After taking away the hard Victorian portland cement from around the tesserae we
built walls of Paraloid B72 and microballoons to protect the stones prior to new fills. 
Another part of the floor that has had the old hard mortars removed and
are being protected prior to new fills.
Lazer cleaned part of one of the tombs that is part of the floor
