When we
turned the furnace on in January, it never reached top temperature. Glass
usually melts at 1250 degrees C. and the temperature never went over 1140. The
glass was melted, but at such a low temperature, there were a lot of bubbles.
An electrician came to assess what was going on, and sure enough, 3 of the 9
elements were out of order. Of course, we knew the day would eventually come
when we would have to exchange parts on the furnace, and that day finally came
at the end of the Agya conference.
So the
other thing about having an electric furnace is that the elements are not that
common, and take a while to produce, 3 weeks, in this case! We bought ours from
Schupp and as they understood our urgency, they produced them as quickly as
possible. Now the furnace is back to its regular working temperature, and we
are ready to blow some glass again!!
