helmer kaolin substitution?

updated mon 20 oct 08

 

Michael Wendt on wed 7 jul 99


James,
Why not have him order the body from
me directly since I mine, mill and mix
Helmer here at the source.
Cost:
38 LB box
$9.50
shipping
$9.30
total
$18.80
He can order just what he needs at the
time he needs it
Ships anywhere in the 48 states, Alaska
or Hawaii for this cost.
The cheapest quote we could get to send
a ton of Helmer to Alfred was $700.
We can mail it for $500 one box at a time.
No old clay. No storage. No money tied
up. Just fresh clay when you need it.

Hi, all...

A young wood-fire potter friend of mine is currently in
grad school. His clay body requires a large proportion
of Helmer Kaolin (most of the balance being Custer Spar
and silica). His new school does not stock Helmer, and
he cannot afford to order any. Any ideas on possible
poor-boy substitution? We are thinking #6 Tile Clay
plus a bit of Red Art and a touch of titanium dioxide
or rutile. Chemically, this seems like it would get
close, but not sure about working properties (his work
is probably 98% wheel-thrown).

Any thoughts?

All the best.

Helmer Kaolin (not Helmar... never was Helmar)
I named it that because it is mined at Helmer,Idaho.
Not just for wood fire anymore...
Helmer is a huge deposit. Bore holed on 50 foot
centers, it has known reserves at the surface of
1.6 million tons. Additional layers go down many
feet. Some of that clay is even better than the top
layer but the cost of extraction is too high for this
sales volume. We mine 500 tons per year.
At that rate, the supply will last 3200 years.
Even if demand grew ten fold, we would still
be able to supply the identical clay composition
for 320 years... longer than most of us will live.
The decline in availability is a consequence of
high shipping rates so we have now offered
to ship small quantities via US Mail for the flat
rate price of $18.80 per box anywhere in the 48
States, Alaska and Hawaii. That's the clay AND
the shipping.
It saves huge amounts of space, avoids the drying
out issue and ties up no extra money.
Try it, you will like it.

mix of EPK, Redart, Hawthorne firclay and a smidge of
titanium (not too much or all your pots come out
grey-blue). Unfortunately, much like albany slip,
there are many substitutions, but none are the real
thing.

Caleb,
I meant no chastisement. I am trying to clear
up the spelling and pronunciation error that has
crept in that confuses people and makes Helmer
harder to find on the web. What a struggle.
If you come here, it is $4.75 per pug (19 LBS).
Dry Helmer is $6.50 per 50 LB bag.

Tee hee. Most educational. I apologize for my

Just out of curiosity, what would it cost to by a
couple hundred pounds if I was passing by the mine and
could drive it home myself?

Thanks,

38 X 6 = 228.

6 boxes is rounding up: 6 X 18.80 = $112.8

James -
Tile-6 doesn't flash very well in salt, soda, and wood. It is quite
plastic, and in the name of particle size distribution I like to include
some in porcelaineous bodies, but I always include a good fraction of EPK or
Grolleg for the flashing. In this case, the Grolleg might be prohibitively
expensive, but Tile-6 and EPK are both very reasonable. I'd make the clay
component of the body 50-50 Tile-6 and EPK.

When I am typing fast I often make mistakes, as you all know very well. I
have been trying to remember to quickly proof my posts. I read this one
over and I had written "Tile-6 doesn't flash very well in salt, soda, and
food." I guess you know what I was thinking about.

Hi James - I have an experiment for flashing slip coming out of a wood
firing tomorrow - I'll let you know if it worked.

Helmer substitutes for Avery. Do they have old Avery in the chemical room?

Check out John Britt's glaze book. It has several flashing slip recipes.
