(The System 96® annealing temperature is 950-960°.)Īfter fusing, during the cooling phase, the glass is sensitive to temperature change from 1000° down to room temperature. This allows the glass in the project to equalize at that temperature. We relieve the stress by holding the glass at an annealing temperature for a period of time. ![]() The process of heating the glass causes stress within the project. Once we have the desired effect, we cool the glass. At 1465°, the glass will completely melt into one smooth piece. At 1365° glass sticks together, otherwise referred to as tack-fuse. At 1265°, the glass will slump and take on the shape of a mold. Over 1000° we can heat the glass quickly to the desired temperature. To avoid thermal shock, which is breakage due to rapid temperature change, we heat the glass slowly from room temperature until we reach 1000°. Glass is sensitive to temperature change between room temperature and 1000°. During heating we take the kiln from room temperature to 1200° – 1500°, depending on the type of fused effect we want. There are two basic stages to the firing process: heating and cooling. To better understand why glass breaks, let’s do a little review. ![]() The base layer is clear, and the second layer is a pretty purple and the third, partial or accent layer is a pattern glass with hints of purple. Our sample project is made of two full layers of glass, plus an accent layer. Let’s take a simple project and break it. You just have to recognize what your broken glass is telling you. We ask why, what was different, where did I go wrong? We rack our brains looking for answers.Īll the while, the answer is right there in front of you. On the rare occasion that the project doesn’t come out well, our disappointment is heartbreaking. When the project comes out as expected, or sometimes even better, angels sing, unicorns exist and a rainbow glows brightly over your studio. We look forward to it with the same childhood glee we have when opening a crisply wrapped gift. I’ve asked numerous students, and most admit that opening the kiln after firing is their favorite part of fusing glass. It’s the mystery of making something new and the magic of melting materials that hook us. Especially if they are placed on a delicate surface.Mystery and magic attract us to glass fusing. We recommend putting felt pads under your products to avoid scratches. ![]() For the Astro Gemini sculpture, the word Communication influences the expression of the figurine's pose and helps describe the unique characteristics of this zodiac sign. The energy of the specific characteristics of the zodiac signs has been translated into the design of the figurines. Each Astro sculpture has been created with a descriptive word based on the values associated with each of the 12 different zodiac signs. The raw expression helps to create dynamics in the figurines as naturalistic details so that they appear as sculptures that can be appreciated from all angles. All the zodiac figurines are made of white unglazed stoneware and stand in a silhouetted look. With the new Astro sculptures from Kähler, the Danish sculptor Malene Bjelke has been inspired by Kähler's long history of figurines and has created 12 different zodiac sculptures that beautifully bring the design heritage from Kähler's historic ceramic workshop into the present day with a spiritual focus.
