Melt at exact temperatures and measure more than just temp.They melt at the right time with time and temperature work on them. That isthey melt with the time it takes to get to a given temperature. Which effects the glaze melt-faster fires melt it less slower rises melt it more. Only cones reflect this factor and melt accordingly.
We take these little things for granted but they really arefantastic
I have been lucky enough to have a huge collection of cones mainly from buying out 3-4 potters who thru in the towel years ago. Also back in the day (1971) was told to throw away all the old cones from the university clay shed I worked in from the 50’s.Those cones missed the dumpster and ended up in use. I have given boxes of extras to our now defunct ceramics guild members over the years.
No matter if you use pre made pads or self supporting or youare like me and always make your own pads.
Next time you place a cone consider what they really do.
I have my cones organized by those used every week and those needed only rarely. I do not use cones for bisque in car kiln anymore and only use two cones per glaze fire-cone ^10/^11 .I’m not suggesting this for anyone. Us old times have our own ways
It is suggested to put 3 cones in with your main cone being the middle cone in pack. This is good practice
Melted cones in the photo are ^10’s and ^11’s.
Get to coning.
