The lampliner would burn out if you fired it. It
is for using after the pot is finished. As I
remember, different brands are to be applied in
different ways. If you don't get the answer you
need, search the archives--there was quite a
thorough discussion of this on Clayart at one
time. (You can find the address for the archives
at the bottom of any Clayart post, and they're
very easy to use.) Also, I've found Axner to be
very responsive. If you give them a call, I'm sure
they can help you.
That said, if you have a good tight clay body, oil
will not seep through. It also helps to have a
good, well-fitting glaze. Given both, you do not
need a lampliner. I have oil candles which have
been sitting in my home, full of oil, since my
earliest days in pottery. These are glazed with a
commercial glaze I no longer use and are crazed,
yet not leaking oil in 5 years or more. I'm a
lucky girl. I hit on a good body without knowing
what I was doing--pure luck. In fact, now that I
think of it, this may be a good test of the
vitrification of a clay body: will it hold oil? If
it doesn't hold oil, I doubt it's a good clay body
for any kind of use where it will regularly get
Many times, a clay body will be advertised as good
for ^4-^8 or similar. This is an impossible claim.
Such a clay body will vitrify (become glass-like)
at one given temperature or level of heat work
(probably, but not necessarily, at ^8). If it is
fired below this vitrification temperature, it
will be too absorbent for ware which will be
washed, used in the dishwasher, microwave, etc.
(Keep in mind I'm talking about stoneware, not
unglazed earthenware baking dishes in which
porosity is a part of the function.)
So, if your clay is not holding oil, do some
experimenting to see what cone it can withstand
without bloating. I'll bet it can (and should) go
higher than you're firing.

I just ordered some Axner lamp liner.
The packing slip said that instructions were included. They weren't.
Has anyone used this product?
Can someone give me instructions as to how it is to be used?
On raw clay? On bisque? On a finished piece that isn't glazed inside?
Is there a ^ maximum?
I fire to ^6 electric.

This product is meant to be used on ***unglazed***, ***fired*** clay. I
tried using it over glaze once and days later the lamps still oozed liner
when turned upside down. If you try this, I would suggest drying for at
least a couple of weeks before you take the work to a sale. (Been there,
