Who makes Seraset? A Google search on seraset comes up with nada.

Thanks in advance,

Hello Lee,

The coating sounds good. I've always thought we could make our own. I
think ITC and some of the other newer coatings are mainly Zircon based,
with some refractory cement. Do any of you Clayartors know more about
Zircon coatings?

I have been using an old product from AP Green called 'Greencoat". It
came along with a bunch of bricks I bought, so there is no need for me
to make my own.

Our posts are just dipped in wash on the ends, and are usually wadded on
both top and bottom. The wads are easy to knock off after firing.

Good Burning,

We sometimes coat our soft door bricks in a mix of:

75% seraset (high temperature mortar)
25% alumina hydrate

This is mixed to the consistency of skim milk and the soft bricks are
completely submerged for a second. They are then allowed to dry on two
thin pieces of wood. (so they don't get scared).

They are then used in a wood kiln which is salted. This gives each brick
much more strengh and it is highly resistant to the salt. We have used
the last set for two years (25 firings) and they are only now beginning to
show wear.

And the soft bricks are not crumbling or cracking in half like they
normally do when they are under weight.

(If you want you can send me $130 for every gallon you mix up. That will
make it reflect more heat and increase fuel efficiency too. Just kidding,
in case you did not know. )

Paul,

Cool kiln. Please send some larger pics.

Ap Green has a product (MaCoat or something like that) that is 95% Zirconium
silicate with 5% binder. A variety of people are testing in including myself
(next firing). It is suppose to be equivalent to ITC but less expensive.

Tony

Thank you.

I just wanted to share a tip I picked up here on ClayArt, from my friend in
New London, Craig Edwards.

I didn't have time to order ITC when I was building my kiln. Craig
told me via private email, that he brushed a mixture of kaolin and alumina
hydrate on the softbrick inside his Anagama and it works to protect the
softbrick from the flames and volatiles in the wood firing. I mixed up a 60%
Alumina Hyd. 40% Korean Kaolin batch and sprayed it on the walls of the inside
of my woodkiln with a compressor spray gun. I sprayed the walls and only
the ceiling over the fire entrance and also where the door bricks go (I didn't
want flaking from the roof, if the mixture didn't hold. After the bisque
firing, as one might expect, the mixture would rub off if you brushed it with
your hand. After the bisque, I put another coat on. It has effectively
sealed the surface of the softbricks pretty well and won't brush off after the
glaze firing. I put a third coat on before my second glaze firing and it took
pretty well.

I'll let you know how it weathers as the firings go by. In Euan's kiln
(same desgin as mine), his softbrick show weathering where the flame enters the
ware chamber and also at the ceiling, where the softbrick meets the door. I
think this coating will give the interior softbrick a longer service life.

Hey, for kiln stilts in your woodfiring, do you just coat the ends in
kiln wash or the whole prop?

Roger, I believe that that is spelled "sairset". I found several listings
by Google search.

It's spelled Sairset; many clay suppliers stock it.

Roger,

Sorry I spelled it wrong. It should have been

Sairset. Try Marc Ward at Ward Burners. Exert from catalogue:


Mortars

Sairset is a wet, high temperature, air setting mortar that is an
excellent trowleing mix to bond fiber, brick, and metal. Made with
colodial silica to provide stickiness. Apply in thicknesses under 1/8".

15 lb pail.....$ 25.00 50 lb pail......$ 62.50
Greenpatch 421 is very similar to SAIRSET but can be used in any thickness
to bond, fill, or coat. Comes wet and ready to trowel.


15 lb pail.....$ 25.00 50 lb pail.....$ 62.50


Sairbond is a high alumina dry mortar with much the same working & firing
characteristics as the wet mortars. It is ready to use immediately after
mixing with water. As Sairbond is a dry material, there is no waiting for
thawing in cold weather. Sairbond does not contain a colodial silica so it
does not have the stickiness of the wet mortars. It is better suited to
bonding brick to brick.
50 lb bag......$ 47.50

Roger,
I think John means Sairset and I know from your past posts that you are well
acquainted with it.
Sometimes spelling matters.
