PAIR OF CERAMIC LAMPS WITH BRASS FITTINGS


PAIR OF CERAMIC LAMPS WITH BRASS FITTINGS

Pair of hard paste porcelain vases standing 29 inches (75cms) with brass fixtures and 22 inches (56cms) the vase alone.  Both decorated using cobalt blue glaze.  Vase 1 has been broken and repaired using 21 rivets which was an old repair method.  I will have to remove the lighting fixtures and the brass fittings on the top rim and base of each lamp before doing any work.  They have been wired using a brown textile covered wiring which appears to be up to date and will be re-fitted when the vases have been repaired.  Now for the examination and dismantling!

Vase 1

Vase 1 - showing rivets

Vase 1 - again showing rivets

Vase 1 - more rivets

Vase 1 - more rivets!

Vase 1 - close up of rivets

Vase 1 - this vase is very dirty

Vase 1 - the base showing fixtures.  It has pads where it has been tightened onto the vase base.


Vase 1 - close up of rivets where the broken pieces meet

Vase 2 - not broken but dirty, which has some glaze popping which happened in the firing process

Vase 2 - showing glaze popping

Vase 2 - glaze popping near to the vase base

Vase 1 - Dismantling of the lighting fitting

Vase 1 - light fitting, pic to remind me how it's been wired up

Vase 1 - Little screw that tightened the base to the brass base (must NOT lose!)

Vase 1 - the top brass fitting that has loosened after I got the base off.

Vase 1 - I took the light fitting off and it lifted away from the main brass top.
I was left with the metal pole that goes through the entire vase with top brass fitting (see photo above) which I was then able to unscrew.  I was then able to dismantle by pulling the electric wire through the entire centre of the vase. 

Vase 1 - As you can see here there is what looks like an MDF/wood fibre shaped stopper
 which holds the rod vertically so that it doesn't move.  Am assuming it's like this on the other one.

Vase 1 - with the top off it has revealed a big chip from the rim, as well as all the dirt!!

Vase 1 - the base without the brass fitting, no markings on the base (mucky!)

NUMBERING THE DISMANTLED BITS

This is really important, and you must do this methodically.  Numbering of all the light fittings with Vase 1 or Vase 2.  Even though they present as a pair each vase is unique and there is a possibility that each fitting has been made bespokely (spelling??) for each vase and sizing could differ.  So to avoid problems later on make sure you do this.  I had to tape up the wires for the lamp switches to get them out through the hole.


Vase 1 - top and base numbered
Vase 1 - stopper and central post
Vase 1 - Four components on base electric fitting

TAKING OUT THE RIVETS

 There are certain things you need to do before lifting the rivets.  You have to take into account that there may/may not be adhesive after you've taken them out.  You also have to remember that there may be 'spring' tension in the ceramic body as the pieces come apart.  This is the tension that exists in the clay body of the vase when it was manufactured.  When it suffers impact damage this tension is released.  To minimize this it is best to tape the breaks with masking tape to hold the pieces together after the rivets are removed.

Vase 1 - Masking tape around the rivet, to prevent the file scratching the vase and to hold the pieces together.  Then using a triangular file or any fine file work through the metal.
Vase 1 - lever gently to try and lift

Vase 1 - you may need to break the rivet to get it off or it might come out with the pliers in one go.....
Vase 1 - you should end up with all the rivets out and masking tape holding the vase together, therefore time to be very careful on handling!!  I did leave ONE rivet in at the base of one of the hairline cracks as a precaution for when it dismantles.


Vase 1 - Tadaaaaa! now Vase 1 in three pieces after carefully taking off the masking tape bit by bit.........

 DISCOVERIES ALONG THE WAY!

Vase 2 - Broken rim stuck with a rather large amount of Evostick!!
Vase 2 - outer view of vase rim

Vase 2 - losses around the base which may have been them forcing the brass fitting on the piece, or just poor glaze adhesion to the clay body during the firing.

ANOTHER DAY....

After having soaked overnight I rinsed and steam cleaned all the pieces, whilst still damp I soaked some cotton wool in hydrogen peroxide to eliminate any remaining staining on the edges on Vase 1 only.  I left this overnight.  At the same time I put some DCM on the repaired broken rim on Vase 2 and covered with clingfilm.

Vase 1 - edges covered in cotton wool and hydrogen peroxide and covered in clingfilm

Vase 1 - Same as above

Vase 1 - Near the base at the base of a very long hairline crack I have decided to leave in the last rivet as a precaution to the crack perhaps carrying on.  When I consolidate the crack it will be more stable and I will take out the rivet when this has taken place.  To the right the handle of my steam cleaner.

Vase 1 - Steam cleaned after the hydrogen peroxide and with the plaster removed from the 42 rivet holes!

 It was a lovely sunny day (unusual for the UK!) and I left the pieces out to dry.  They're now ready to put together.

Vase 1 - colour matching with special epoxy and historic pigments

I put the vase together in two stages, the side piece and then the top sectionholding the pot together using masking tape whilst the epoxy cured. It is important to use nitrile gloves at this stage otherwise you find you've got finger prints all over the surface that you hadn't noticed before! I used masking tape as it is quite strong and the pieces were heavy.  After re-construction of the vase using special epoxy I mixed up some more to do the fills and the rivet holes that were left after removal.  

Tinted fills after vase was re-constructed

Fills with tinted special epoxy

After doing the fills and where the rivet holes were (42!) and glaze losses to the base, top rim and all the small glaze losses that I discovered in the body.  I then sanded down using micromesh to just below the level of the top glaze and to enable space for the colour tint.  Using Golden colours I tinted them to colour match the darker cobalt blue as I didn't need to colour down the base colour (paler blue) of the fills as they had been colour matched.  I then painted several coats of Golden colours to infill the pattern that was lost, the leaves, the cross-band pattern and the handles on the side.  I then sanded down the re-touching with micromesh to achieve a smooth finish, repeating the procedure until I was happy with the result.  Observational skills really come into play here and time taken to study your work usually shows somewhere that has been missed.  Best to leave it sometimes and go back to it with a fresher look.

Completed vases,  Vase 1 (rivets) is on the right

Finished with the brass fittings and wiring attached.

It took me a good hour and a half to get the brass fittings back on these vases, loads of fiddling about and trying to be careful at the same time!  I was able to put an additional thin circular padding of Plastazote™ underneath the top section as there was none there previously.  It would add more protection to the ceramic rim when the bases were screwed tightly.

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.

Recreation of flower and extended finger

The finished lady with her missing finger and flower remodelled and tinted.

The final pictures..
