Cone 6 / 1200°C

Almost 5 years ago, me and Prof. Tizgol from Akdeniz University conducted a small study about mid-range ceramic glazes. Tizgol, works on and teaches contemporary ceramic art, as well as, ceramic technology. Under the supervision of him, I prepared a mid-range glaze catalogue which includes 36 recipes. Glazes, which are fuse to ceramic body properly through firing at Cone 4-7 or 1165-1210°C, are classified as mid-range glazes. But, within the scope of this lab study, we specifically focused on 1200°C in other words cone 6 which is the most popular temperature in clay world.


For this catalogue, I examined already applied and proven glaze recipes as much as I can. I revised them according to the available raw materials and did over hundred experiments. In the light of the results, new alternatives were created and 36 final recipes with healthy results were inventoryed. In general terms, test results can be defined as matte, glossy, semi-matte; textured, smooth; opaque, semi-opaque with various color and shade options such as; green, blue, black, yellow-brown, white and pink-purple.

For these experiments; Eczacıbaşı ESÇ-3 (white), Creaton 25% chamotte Nr354 (red) and a basic chamotte clay were used. The biscuit firing of the bodies was at 900-920°C in a chamber type electric kiln. They were glazed by dipping into 40 grams blends of water and ingredients. I used 5 different pebble stones’ form as a test plate design for seeing the results of glazes on a minor 3D form.

Building process of test plates

Most of the glaze recipes are not recommended to apply to daily used object especially for food and drink purposes. The original study can be watched in the ceramics laboratory of the Faculty of Fine Arts, Akdeniz University (B14-b).

Recipes, calculations, notes, diaries, surprises, miracle, changes, stubborn ingredients, power of firing, potential of materials, results, disappointments or satisfaction are all part of this study like any other lab experiments on ceramic glazes. Please see the attached document to find all these precious moments and steps. Enjoy!
