Some years ago the Chi Lin Nunnery built a Chaschan kiln in the Chinese mainland (Dongguan City) in the old tradition of early Chinese cloisters and nunneries. To study old pottery techniques, master Gao Feng was asked to train new potters. Every year, two potters finish their education in Dongguan. In spring 2017 I was… Read More

2017 I had again the opportunity to admire the results of the (2016) tea pot competition of the local potters. ” order_by=”rand()” order_direction=”ASC” returns=”included” maximum_entity_count=”500″]
HongKong´s local potters participate every two years in a tea pot competition (Tea Ware by Hong Kong Potters Competition). Several categories exist, even school classes have their own category. The results are exhibited for several months in the “Flagstaff House Museum of Tea Ware“, a subsidiary of the HongKong Museum of Art. ” order_by=”rand()” order_direction=”ASC”… Read More
The Some-Bright-Green Glaze is formulated especially for wood firing with salt and soda. Iron as well as copper and titanium are responsible for the green colors. Very nice is also the modification of the recipe with additional 3% Copper Oxide.
Nezumi-Shino (mouse-gray Shino) is very famous and is achieved by overlaying a Shino glaze (e.g. Currie Shino 2b) over a Gosu slip. Then the surface needs to become textured. The original Gosu receipe (e.g. from B. Leach) is difficult to create, as one of the ingredients is black Cobalt Oxide, which is very special and… Read More
Glossy Nuka Glaze is getting especially nice, if metal oxides cause color streaks (e.g. iron oxide or cobalt oxide). 56,2 Custer Feldspar 11,2 Talcum 11,2 Bone Ash 33,8 Flint 22,4 Whiting 11,2 Bentonite 37 Wood Ash 16,8 Frit 3134
Easy white glaze, getting dull in combination with ash.
The combination of the two coloring components Cobalt and Titanium result in many different green colors. However, Cobalt blue can show eventually. 140 Nepheline Syenite 4 Gerstley Borate 16 Ball Clay (Hymod AT) 10 Talcum 30 Petalite 2 Cobalt Carbonate 4 Rutile
This glaze achieves it´s beauty by superposition of a white and red Shino glaze. Half of the white glaze is enriched with 10% red iron oxide. The red Shino is applied first. When dried, the white Shino is thickly applied and then decorated while still wet. The red Shino from below shall be visible.
Glazes with a high iron content (Temmoku, Oilspot, Tea Dust) are the logical continuation of the Seladons glazes (low iron). Bailey´s Red Glaze The recommended sp. gr. is 145.
A fantastic glaze in principle, but it is not easy to get reproducible results. According to literature, the glaze should have a spec. gravity of 160 (1 liter glaze should weight 1.6 kg). It is mandatory to apply the glaze very thick and on both sides, to avoid tensions.
The simpler, the better: 80/20 Nepheline Syenite and EPK. Beautiful red-orange if applied thin (spray gun), no run-off at 1300°C if applied thick, does not crackle and can become very white. For your info: all experiments have been performed with Wittgert 11sf 0-0,2.
Shino Experiment 3: Penn State Shino
Variations of the flux. Penn State Shino: 14,6 Nepheline Syenite 34 Potassium Feldspar 29 Spodumen 9,7 Standard Kaolin 4,9 Hymod AT 7,8 Soda (calz.)
Shino Experiment 2: Shino Currie 2
A very simple recipe: Flux and variations of Kaolin. Shino Currie 2a: Standard Kaolin Shino Currie 2b: EPK Significantly more red with EPK, if applied thin (see also inside of the cup). If applied thickly, glaze is getting real white, as can also be seen in the picture, where it has been placed on top… Read More
