For another, it cannot correctly heat and then cool the ceramic pieces. For one thing, conventional ovens do not reach the required temperatures to properly fire the ceramic. Unfortunately, a conventional oven is not built to handle ceramic pieces. It will have to be refired in order to fix the piece. If the piece does not reach the proper temperature, the paint will not harden correctly or gain its true vibrancy. If the ceramic is not fired long enough, it cannot reach the correct temperature to properly fire. What happens if it doesn’t fire long or hot enough? The weather, the amount of pieces in the kiln, how tightly packed the kiln is, and several other factors all work together to affect how quickly or slowly the kiln will heat and cool. The entire process usually takes 2-3 days. The kilns are specially design to heat up and cool down at the best rate to ensure the safety of the pieces inside. Pieces that are heated up too quickly or that cool too fast can crack, or even explode. Why does the firing process take so long?Ĭeramic pieces are fragile and require a lot of care. Ceramic paint requires very high temperatures in order to harden and change color. We get a lot of questions about this part of the process: Our kilns are a bit more modern: they are electric! All it takes is a few button pushes, and the kilns are off! Once all the pieces are loaded, the kiln is sealed shut and the firing begins! In the days of old, kilns operated using an actual fire, or the use of coal. An average load of the kiln usually holds anywhere from 40 – 60 painted pieces. We use adjustable risers to change the height of the shelves so we can fit as many pieces as possible into each load of the kiln. Ceramic pieces will stick to anything they touch during the firing process: the shelf, the walls of the kiln, even other pieces! Each piece is placed on a stilt to keep it from touching the shelf and is carefully placed to avoid brushing up against other pieces. The process of loading the kiln requires precision and care. The firing process takes anywhere from 2-3 days, depending on several factors.įirst, pieces are loaded into the kiln. Treat yourself to some people watching and retrospection. After the over glaze dries, pieces are placed into the kiln to be fired. PISCES (February 19 March 20) Dreamy Pisces, you are wise, empathetic, and fiercely creative. Firing brings out the true color of the ceramic paint and hardens it into the shiny, glass-like material you’ll see when the piece is completed. Firing refers to the process of baking a ceramic piece within a ceramic kiln.
