For more than 37 years David Fry, has experimented with recipies gleaned from the ancient glazing techniques of the East. Combining extensive research and intuition he has successfully reproduced their form and styles. He has developed a ‘Lang-Yao’ or Flambé, a copper red glaze, a rich blue ‘Jun’, a green Celadon, and a Black ‘Tea Dust’ Tenmoku along with Shino and Wood Ash glazes.
Using a 40 cu.ft gas fired kiln, which he built himself, his prime firing technique is ”Reduction” firing. ie. he reduces the amount of oxygen entering the kiln and introduces wood to to create a smokey atmosphere at the end of the firing process. All his glazes contain some wood ash, which are utilised to introduce Phosphorous and Calcium. ( absent form standard glaze materials.) This wood ash is obtained from burning recycled wood and hedge cuttings ( Wild Rose & Hawthorne ). Each pot is overlayed with up to 5 glazes to enhance their colour depth and variety of colour mixes. The firing takes about 24 hours, where a temperauture of 1340C is reached , followed by a cooling stage of 48 hours. During the cooling stage , changes still occur in the colour tones of the glaze as the crystals oxidise. Some of his glazes have a crackle pattern within the glaze structure, much loved by collectors of Oriental ceramics.
David claims that “my glazes or materials do not contain any toxic materials, and the glazes have a high percentage of Silica and Alumina being fired at high stoneware temperatures. The principle fluxing element in my glazes is Calcium combined with smaller amounts of Potassium, Sodium and Magnesium. Therefore my work is safe for the user, the maker, and the environment .The colours of my glazes come from very small amounts of copper and iron in the glaze mix – reduced copper turns red and iron blue/green.”
David Fry is currently based in a sudio at the new Arts Centre in Newcastle, Britain. He is continuing his quest to discover more exciting colours and textures, drawing his inspiration from the endless variety of unique outcomes he attains from his combination of glaze mixtures and firing methods.
