I only melted some metal with it but never did ceramics. It is an UHLIG U15, I think they are still sold. Max temperature 1050°C, draws 900W, so at 230V little less than 4A. Now due to 3D printing I thought of some neat ideas that could be done in combination with the kiln. So I deceided to build a control unit for it. At this point be warned, I take no responsibility for the things you are doing,  especially not when it comes to high voltage or high temperatures.  Do not play games if you don't trust in what you are doing. The cheap kiln usually don 't have any control units, with some luck you can buy some random on/off control for them but there is no real temperature control.  My version got it and you can program different times and temperatures. You need the following things: Thermocouple element, I got
