The term "seraset" has been posted to the list as the product name for a
refractory repair material. Just in the interest of clarity and to save
someone time in the future, the actual name is Sairset, a product which has
been made and sold by Harbison-Walker (now part of ANH Refractories). It is
described as a wet, high-strength, high-temperature, air-setting mortar,
mixed for a troweled joint but can be thinned for dipping. It is sodium
silicate fluxed. Works best in VERY thin application between pieces which
otherwise fit very well.

Sorry David,

My mistake. It is Sairset.

Just as a further elaboration, Sairset is one of the legendary AP Green
products which became a Harbison-Walker product when they purchased AP Gree=
n
around 1997. ANH Refractories now makes Sairset, and the name "ANH"
combines the first letters of AP Green, North American Refractories, and
Harbison-Walker. They are still making products from all three companies.
Among the AP Green products that ANH still manufacture that are very popula=
r
with potters, Sairset is a thin-application mortar (as Dave Finkelnburg
reports above), Greenpatch 421 is a super-duty pre-mixed bonding
refractory-repair mortar that can fill spaces, and Mizzou castable is one o=
f
the tried-and-true super-duty castables for things like burner ports and
flue and damper lintels in very high-duty applications like salt, soda, and
wood kilns.
