Hi Henk,
Thank you for the information. One thing I have noticed today was that the paint I used the carnation oil in turned my piece of Plexiglas cloudy where it was sitting. (I use a sheet of Plexiglas to keep my test dabs on )
As Letha said some painters use lanolin for the gritty paint. I believe Andrew Orr started telling us about this. But again, I haven't noticed a lot of difference. Maybe if I stated grinding with it from the powder instead of adding it to the mixed paint it might help but from what I understood him to say, he just adds it to the mix.

Hi Sam, I have tried copaiba, Fat oil, Oscar oil, mineral oil, Jojoba, two types of water base medium. Also adding a bit of flux. The best shine was obtained with Copaiba and Fat oil. Adding flux did not improve shine or helping for gritty paint but only fading the color. Gritty paint can be improved by grinding in a porcelain mortar or using a glass pesttle on a glass plate but it cost me years to find them in Germany. Very effective is tumbling the powder when you have larger quantities, I have used that and it works great but only when you have more then approx 50 gram. A simple but less effective method is using a strong hard palet knive on a matt glass plate to grind the powder and smooth it. Much more simple is buying a better quality paint Henk

LOTS of work and LOTS of good information in the dictionary. Thanks for making it easy to look up what we need!
I asm so glad to see how to repair broken pieces! Repair mixture. A repair mixture to 'glue' back on a piece of broken porcelain can be made by mixing dry Base for Gold powder with Elmer's white glue. Mix until clay like and then stick the pieces together. Be sure and let it dry before firing. This will also repair cracks that are forming and will prevent the crack from going further in most cases. Fill the crack on both sides of porcelain and make sure it's mostly on the edge that is going toward the centre of the porcelain. See; Elmers White Glue

We have Base for Gold here, I believe it to be a hard enamel. Fires with a shine, and is less likely to scale than most enamels.
I mix mine with Dark Balsam of Copabia to a paste consistency, and thin it with Turpentine. When it strings it is right. You need it looser for dots, and firmer for scrolls.
Personally, I don't mix with glycerin, some do mix it with with Glycerin but to each his own.
I have mixed it with Milk and drizzled it on Ornaments. Dropped fusible glass into it, and fired 016. Then put Liquid Bright gold over the Base For Gold and fired again at 018. Popular with most people, and a good seller. Sometimes I use Luster to add color to the Christmas Ball too. This may not be in the right place, Henk, Forgive me if it is. Cherryl

Hello Henk, I was looking for "Wink". You give the explanation, but would you know of a same product available in France ? instead of drilling the faulty spot ? Have a good Sunday Francoise, Melun France with the cold sun and frost all over the place

Hi Francoise, As far as I know is whink not allowed in the EEC. And for good reason, it is to dangerous to use. Your health is much more important than a piece of porcelain. When you insist to etch a spot in your painting a 20% solution of ammoniumfluoride can be used using rubber gloves and being very carefull not to spil it on your skin. It is in the US on the market as Etchall. For info mail to etchall@etchall.com. Henk

Hi All, As there is some misunderstanding about the types of glycol I added information on the toxic Ethylene, diethylene and buthylene glycol's and the non toxic Propylene glycol. Unfortunaly all types are sometimes used in water based porcelain painting mediums. So ask for the ethylene, diethylene and buthylene glycol free type. Henk

Dear Henk,
Since lanolin is absorbed through the skin,does lanolin raise a persons cholesterol level ? That may be an unknown answer. Thank you for this information

Dear Tami, Good question, As we have cholesterol in all our cells and Lanolin (being for 1/3 cholesterol) is used to transport medicines into your skin what more is going. I do not know the answer. Henk

Arabic gum. Arabic gum or “Gummi Arabicum” is the oleoresin of the tree Acacia Senegal and contains mainly sacharides and glycoproteins. It is used for postal stamps as wetted with water it becomes sticky. In porcelain painting it is used in water based mediums. Other Acacia trees give comparable gums.

Hi All, I added a new item. My dear wife Ans tried it and the results are great Henk ======================================
Scratch technique Scratch technique is a method of backgrounding designs. A quick drying waterbase medium is used to mix the paint. First the mixed paint is applied with a sponge. After complete drying of the paint design can be scratch in the paint with a sharp pointed hard wooden stick. Whipe off excess paint with a soft brush. When a matt white or pink base for gold is used as paint en after scratching the design fired and then a luster (e.g. Mother of pearl) applied and again fired, only the scratched parts will show the shiny lustre colours.

J added the following item. ==========================================
Black stoneware, Black Basalt, Egyptian Black Basalt. Stoneware with a body completely colored black with cobalt and manganese oxides, fired in the range of 1200-1315°C to a normally partially vitrified state. Josiah Wedgwood first advertised it in 1774. See also Porcelain noire.

Crystal Magic. How it works. A thick fluid containg naphthalene, paraffin wax and a plasticizer dissolved in a mixture of organic solvents. Use a thick coat and let it dry completely. The naphthalene forms needle like crystals in the fluid. After evaporating of the solvents and the naphthalene, the paraffin wax and plasticizer stay behind, still showing the needle like structure. Direct firing will burn away all of it, but covering it first with luster or any porcelain paint followed by firing will result in a difference in contrast showing the same patterns.
In case of using the crystal magic in unfired condition any organic color can be added to the fluid to give an extra color effect.
Naphthalene and the mixture of organic solvents are toxic and highly flammable. Keep away from open fire and use very good ventilation. When fly’s are dropping dead the ventilation is not sufficient enough.
General Composition. Crystal Magic contains the following basic ingredients: Naphthalene (naphthene, cycloalkane) as crystalizing component Dibutyl phthalate as plasticizer Paraffin (alkanes ) as filler Further as solvents; Methyl ethyl ketone (methylaceton) Acetone (dimethyl keton) Cyclohexanone (cyclohexyl keton) Isopropyl alcohol (dimethylcarbinol) Hi-flash naphtha ( contains; n-pentane, hexane, , and short chain hydrocarbons.) The ingredients, except paraffin, are very hazardous and highly flammable.
