I saw a woman firing raku, five years ago or so, using this glaze and it came out a lovely burgundy matt. I just recently got my raku kiln up and running and my first try with this recipe yielded a glossy green:-? It was suggested to me to fire it to a lower temp and to reduce it in a smaller chamber. At any rate, this is the recipe and any other suggestions to make it work would be welcome. I fire this on dark stoneware (Death Valley) from lizzardol@aol.com

On that copper Raku vein going on I thought I should throw in my two cents worth. I like this glaze because it is a little shiny and no pocket squeezing cobalt. Fire a little hotter (I don't raku with cones, so I keep an eye on when it 'slicks off' good) or it does a bizzare bubbly green mess that won't reduce. submitted by: Barbara Webb e-mail: barbara@atl.fujikura.com

> ClayArt Listserv recipe comments: This is to LJ in Alexandria and anyone else interested in raku glazes. We have been using these two glazes along with white crackle and copper wash and have gotten VERY NICE results. This glaze is a very pretty turquiose crackle that turns to copper penny luster with heavy reduction. Apply 4 coats with brush over white stoneware (we use Miller 510). The glaze tends to crawl if applied too thin. Again reduce with pine needles and shredded paper if flashing is desired. If not, I pedestal my piece and use only shredded paper to avoid scarring. Quench with hose to bring about crackle. source for original recipe: Robert Piepenburg submitted by: Debbie Altschwager e-mail: MAltsy@aol.com

can also use Black Iron Oxide. I, too, am restricted to an electric kiln and a Raku garbage can kiln in the backyard. Using the Raku kiln for reduction (closing the damper and tiger torch port completely after seeing the glaze melt), I have produced some greenish blue celadon-like bowls. Similar results have been obtained with a straight forward raku firing.. Try the following which is more or less a cone 08 glaze and can be easily modified. submitted by: Francoise, Ralph Melville e-mail: rmelvill@awinc.com

7mls. of dissolved solution (below) = 1.50 grams (less stable)Silver nitrate is poison and corrosive. In solution, if spilled, it stains the surface a revolting liver colour forever. If splashed on hands or skin...liver again for many weeks. Rehearsal for age spots. Crystals are the way to go. Silver nitrate crystals are weighed by grams and added to distilled water. The ratio is one gram to 10 mls of water. So 5 grams go into 50 mls. etc. Store the dissolved solution in a coloured bottle and keep it out of light. When measuring the solution to be added to your glaze WEAR RUBBER GLOVES,CLOTHING YOU HATE and open the windows wide. This stuff doesn't smell at all but it's powerful . Add the needed amount to the MIXED and SIEVED glaze and stir carefully. It will make the texture of the glaze peculiar at first, sort of curdled but keep on stirring and it will smooth out. Wash the stirring implement thoroughly especially if it's metal. This glaze is best painted on in three smooth coats. Use a special brush for this glaze as it will be perm. stained black.

Some one on the list recently asked for a purple raku glaze. What I thought I had here when I was mixing it was a copper matt untill I lifted it out from under the reduction can. At first it was almost black but inside of 15 mins it is the deepest prettiest purple I have ever seen and I have no idea who gave the receipe to me. They sure do deserve credit. I sprayed this on JM5, a buff colored ^5 stoneware I had bisqued to ^08. I fired it in a small old electric I sometimes use for raku to 1830. After pulling it we went right to a pile of sand with 8' x8' piece of slick newspaper on the botton and as we covered it we threw in another the same size on top of the pot, covered it with the can sealing the edges, waited about an hour untill it was cool enough to touch and got the purple surprise. If someone uses this glaze I would really like to hear about their results. submitted by: Lori Wilkinson e-mail: lorwilk@lookingglass.net

Add the following to the base to get purple: 4 Manganese dioxide. 1 Cobalt oxide. I am sure that the above mixture added to any base will do the trick.

Use Borax Decahydrate. Here, designed by me, are two copper red matt lustres. This one is for fresh mix daily, or dry mix and wet only what you can use in a day. The borax is washing machine borax. Pemco frit 830 or Hommel frit K3 will work also. Use a few drops of detergent to disperse colorant oxides. The above glaze is quite fluid at C07/06 and needs to be heavily reduced. Move from kiln to reduction medium as quickly as possible and leave 20 minutes or so. It produces brillant reds with some blue flashes. High gloss finish most of the time. There you go. I have used these glazes with good results. They are BTW variations of Carol Townsend's original 'Tomats Red' submitted by: Tom Buck via Rob Curfman e-mail: Tom.Buck@freenet.hamilton.on.ca.

Firing temp give as ^016-010 For silver lustres use silver nitrate in the amount of 2.1% and soda ash in the amt of 1 gram per mix. For silver lusters with greenish tints add chrome oxide in the amount of 1.2% to above. For silver lusters with bluish tints use the first variation and add 1.1%_____________________________________ Nan Dufresne, an old lady in NE Wisconsin nan dufresne

1 gram of silver nitrate is 10 mls. of the solution below ( that's one dissolved gram) Silver nitrate is poison and corrosive. In solution, if spilled, it stains the surface a revolting liver colour forever. If splashed on hands or skin...liver again for many weeks. Rehearsal for age spots. Crystals are the way to go. Silver nitrate crystals are weighed by grams and added to distilled water. The ratio is one gram to 10 mls of water. So 5 grams go into 50 mls. etc. Store the dissolved solution in a coloured bottle and keep it out of light. When measuring the solution to be added to your glaze WEAR RUBBER GLOVES,CLOTHING YOU HATE and open the windows wide. This stuff doesn't smell at all but it's powerful . Add the needed amount to the MIXED and SIEVED glaze and stir carefully. It will make the texture of the glaze peculiar at first, sort of curdled but keep on stirring and it will smooth out. Wash the stirring implement thoroughly especially if it's metal. This glaze is best painted on in three smooth coats. Use a special brush for this glaze as it will be perm. stained black.
