Hi all,
As a newcomer to glaze testing I would greatly appreciate some advice from
those who know.
I inherited a 25 kilo sack of powder labelled "Frank Hamers Matt Talc"
(and was born with a reluctance to throw things away!) My first
question is does anybody have the recipe for this (what's in this apart fro=
m
talc?!) and
what its maturing temperature is? -I have searched glaze base and the
clayart archives.
25kg of Matt finish doesn't really appeal and from what I've read up on
so far, it would appear that I can alter the characteristics and lower
the maturing temperature of this glaze by the addition of frit and
colourants. -Is it really that simple?
Could I realistically produce some stable mid or low fire glazes from
this, or would my time be better spent starting afresh with raw
materials? The chemistry fascinates me, however, I'd appreciate someone
who knows preventing me from wasting my time!
Many thanks
Lesley Verbrugge

Hello Lesley:
I checked both editions of Frank's book for any referece etc to the Matt
Talc. Found nothing. He does give some glaze recipes of his and his
wife's in the book. The temperatures for his glazes in the book are 1260
and 1280 C.
If you haven't figured this out yet, why not ask Frank? I'm pretty sure
he's still around. I have an address and phone for him if you'd like to
get in touch with the one person who should definitely know what the Matt
Talc thing is all about. I think he lives in Wales. Anyway, let me know
if you'd like his contact info.

Lesley,
I live a few miles away from Frank and I know that he is not on the
Internet. So I have taken a copy of this and will post it to him. When I
get an answer I will post it on Clayart.

Lesley,
I understand from my answer-phone that Steve Mills also saw your post on
Clayart and that he telephoned Frank Hamer yesterday, so I expect that
you will hear from Steve. I understand, however, from the message left
for me that the glaze is one of PotteryCrafts and should be for firing
at 1200 - 1250 C not 1280 C as suggested by Craig.
With a quantity of 25 kilo I presume that you will test it and see what
use you can make of it.

Frank and Janet Hamer fire to traditional
stoneware temperatures in the 1250-80C range, so
if it is a recipe he uses himself, it will be up
there. Of course it is impossible to tell if that
is the case or just a recipe he included in one
of the several editions of their dictionary or
another published sources such as Ceramic Review,
which has featured a great many articles by Frank
over the years.
Is the writing on the bag by hand or printed?
Because, there is also a possibility that it is a
commercially produced glaze which was given a
Frank Hamer moniker, whether it was formulated by
Frank or not. Well known potters are always good
for sales... So it could be an glaze fired to a
lower temperature... Not likely in my opinion
(being matt) but possible.
I am sure Steve Mills will be able to tell you
more and if not, we may be calling in on our way
to collect "The Path" panel off Ned Heywood in
the next couple of days and I will ask. The
Hamers are so well organised, they may be able to
give the gen off the top of their heads... I am
sure I would not after 60+ years of being in the
business given the many changes during that time,
but if anyone can, they will!

Have to say thank you to all who have helped both on and off list. My
connection has been playing up, hence my tardy reply!
Once again, Clayart has come up with the answer! Steve has indeed passed on
the recipe. No-one has 'warned me off' so I'm going to carry out some tests
after Christmas to see if I can produce some lower maturing glazes. I'm
really looking forward to getting my first line blends under my belt! Stev=
e
has mentioned upping the Potash feldspar - Am I right in thinking that I
could also use any LT frit to reduce the temp?
Once again, thanks for the help
Merry Christmas to you all!
