I was searching for information about building a fiber gas-fired test kil=
=3D
n
and following various threads when I came upon a message from Lori Pierce=
=3D
about colloids and how colloidal silica is a rigidizer for ceramic fiber.=
=3D
=3D20
What caught my eye in particular is that she is from Rockland, Maine and
notes that there is a colloid plant in that city. I live just north of
there in Camden, Maine and know all about that plant. Should mention tha=
=3D
t I
have been a potter in Maine for 37 years, 25 of them in Camden.
I'm sorry to disappoint you, Lori, but that plant makes carageenan from
irish moss seaweed which is used as a dispersant in things like ice cream=
=3D
,
toothpaste, yogurts, etc. Wouldn't do much good to try to make your own
with silica and carageenan. Not sure how they make colloidal silica, but=
=3D
I
doubt it's as simple as mixing those two ingredients together. Your use
with paper that you mentioned makes sense as it is not a heat treated
object. Best to just buy the rigidizer material as it was intended if
you're planning on using it.
I knew the man who started that colloidal carageenan plant in Rockland. =

His
name was Victor Legloahec and he used to own a cottage down in Friendship=
=3D
next to my family's summer home. He was very French in speech and
mannerisms. He is long since gone.

Good to hear from you Peter...You knew me as Lori Rudolph years ago when we
were both at Haystack in Cynthia Bringles workshop, long before your caving
days I believe!
Your comments on my old posting which referenced colloidal silica as a
rigidizer for ceramic fiber sent me to the computer and Wikipeg to learn
more about colloids! My face is red; Of course I knew Rockland Colloid made
a stabilizer for icecreams etc but in ignorance had no idea the field was s=
o
broad and their work so specialized.
I will be interested in how your litttle test kiln comes along...Rick Berma=
n
in Atlanta might be of some help...he has worked with the Olympic Kiln
Cmpany and was 'poster boy' for one of their fiber gas raku to ^10
kilns...not the configuration you are looking for I think, but a cousin.
Good luck. Lori Rudolph Pierce, Orange Park, Fl.
