Glaze results vary between different brands of digital kilns because the
firing schedules in the Cone-Fire mode probably differ. This may also be a
reason that one brand of kiln fires more slowly than another.
Also, every kiln has its own unique firing characteristics. Even kilns of
the same brand fire a little differently.
Another variable that affects glaze is the thermocouple (temperature sensor)
on a digital kiln. The K-type thermocouple drifts in its temperature reading
as it ages. To avoid this problem, order a kiln with the S-type
thermocouple. The S-type is more expensive, but if you fire to cone 6 or
higher, it doesn't make economic sense to use a K-type thermocouple. The
S-type ordinarily lasts for many years of constant use without temperature
drift.
Venting kiln fumes to the outside near your living room window may be a
problem. One option is to extend the vent up high outside using PVC pipe. I
would also keep the living room windows closed when you are firing your
kiln.

I read different kilns can give different results with glazes even using
the same firing schedule -Does anyone have opinions or advice on this?Is it
mostly just getting to know whatever kiln you own or are there some definite
advantages to certain kilns when you are mixing your own glazes? I am
defintely venting the kiln from the bottom and may put a vent on top. I
heard that is too much venting but I want to make sure the area is cleared
of toxins as it is in our basement. Our basement window that we are venting
from is directly under our Living room windows. Will that be a problem for
the toxins coming back into the house after being vented outside underneath
the living room windows?
