brown stained royal doulton - restoration
« on: March 17, 2011, 04:16:31 am »
Hi has been awhile. Hope everyone is well. I am wanting restoration info I guess. I have purchased a very old piece of royal doulton and it has brown staining on it. It has a print but this is not affected and I believe parts of it are hand painted. I have researched and only find recipes that will take 6 months to work. Is there a safe, faster way? Ta

Hello Again,

Let me be the first to ask... could you post some pics?  ;)

BTW ... did you ever sort out that little glass Robin with the shop?

as to the robin I loved him so much that I never bothered contacting the shop. They obviously didnt care about ripping people off so I doubt they would do anything... he has pride of place in my cabinet. Have attached pic of my stained platter...my new true  love lol any advice on cleaning appreciated

That is unusual, I've never seen that. Then again, I don't have much pottery/porcelain experience. Are we sure it's not supposed to look like that? Is it the design? You can see it better than me though, so I'm sure you can tell that it's not supposed to be there. ;)
This mentions Napisan but I wonder if it is only for surface stains. Is yours on the surface or underneath?

I also read that it could be from washing it in water that is high in iron but can't find anything about how to fix it.

I frequently see old porcelain plates and bowls with that brown staining. The staining seems to be in the lower quality give away pieces with store advertising on it that have been used daily. I think it is something in the food or wash water that gets under the glazing when crazing develops. I do not find it offensive unless it is really dark brown stains that mask the design or advertising printing. I do not think you can get rid of it. JMO.

Agree with wayward.  It is usually from a low grade glaze and has had "seepage" of water over time.  Now, if you feel the piece and it "feels" like something is on the surface (and isn't slick/smooth? then it can be mineral build up on the outside.  Otherwise, you can ruin/devalue the piece by trying to "bleach" out the stain in the piece.  

This series "Under The Greenwood Tree" was made after the World War and the pieces, if in pristine condition, still sell for a pretty penny!

use only 40% hydrogen peroxide. This is not the peroxide you buy at the chemist. You need to buy the stronger type that is found at a beauty supply store. Always wear protective gloves to protect your skin and pour into the plastic container. soak the items sometimes for a month, and up to 6 months. I like my items to be completely covered as they soak.
The peroxide loses strength over time. You will know when to replace the peroxide because it tends to get discolored, and starts to have an odor. The brown crazing is usually old grease that has become trapped in the crazing of the glaze. This old grease darkens with age.
If I have a piece of porcelain that is more delicate, and I don’t want it soaking in peroxide for any length of time, I simply wrap the piece in old white rags soaked in peroxide, only putting the wet rags on the spots that need whitening. I place it in a large rubbish bag, and seal it. If using rubbish bag method, the rags will need re-soaking every few days, as they dry out.

Clean your pieces very carefully

Use great care with any cleaning method. It’s a good idea to try the method on an inexpensive piece before attempting to clean valuable pieces. After you have the piece as clean as you can, wash it with soap and warm water to clean off and residue of the peroxide.

NEVER USE CHORINE BLEACH! This will destroy the pottery, porcelain or ceramic piece. It literally eats it from the inside out. It makes the glaze flake of the piece.

Also, please make sure that you carefully look over any piece that you are going to soak. If restoration or repair has been made on a piece of pottery, porcelain or ceramic, chances are the piece will be ruined in this cleaning process. If in doubt ask a specialist in restorations before you try this.

Its a good idea to test a small unseen area first if possible

Gingertom, do you have any before/after pics? It would be great to see some and maybe add this info to the Special Threads section?

do you think the brown would lower the value. I dont want to sell but am interested to know. I have checked and there is no crazing that I can see.

Yes it is devalued,
 staining is never a good thing, also in UK this type of plate is not a rare, in general the rule for ceramic collectors is it must be perfect. There are some exeptions like delft
