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.

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.
