I was at the space today trying to use the kiln in blacksmithing and found that it heats up very slowly. I’m not sure if this is intentional or not, I’ve not looked into the specific kiln.
I did start tracking the progress though based on the temperature readout. I started tracking it at 293 degrees and recorded about every 15min. I found over the course of 1.5 hours it reached 337 with every 15 min being a 6-8 degree increase. Seems like it was increasing linearly so I suspect that the insulation is working well and the slow rate is due to either the heating elements, controller board, or probably most likely would be a software thing.
I’ll try to take a look at it next weekend to get more details but if it’s not a software limit would we be able to leave the kiln on overnight to preheat for use the next day? The limit on the kiln is 2300 degrees. Starting at 70 (the initial reading today) it would take ~70 hours or ~3 days. To get to 1250 (slightly higher than aluminum melting point) it would take ~37 hours.
Another question is do we have tongs for holding crucibles? I didn’t see any one the rack
