Topic: SCAA Color Cards (66 msgs / 1246 lines)
1) From: ginny
if I could get pics of the colors I could fire tiles...
not a big deal, just a little time in getting the right glaze fired.
thoughts?
ginny

2) From: ginny
I was thinking more like roasting to the perfect color and then matching the glaze to the bean. hence a pic to getg the color good. maybe I will just buy the color cards and match them.

3) From: ginny
just plain Mike:
thanks for you kind offer.
just talked to a friend who may have a set for me for FREE (read we like free) and I can go from there.
my new kilns will be here in a week or two and I will get started. my guess is 30/60 days, we must consider
test time. I will fire them in a gas raku kiln which may help retain color. maybe? testing this idea I got;
in the end they will be inexpensive to produce and it sounds like tons of Traditions to me!! heck, I would sell them
too... great giveaways for the Summer Gathering I too...
ginny
I have time now to play with my other projects and fun stuff

I have a set of SCAA chips coming next week. I am going to use them to do some sets in the gas raku kiln and se what happens.

I will play with the thoughts while waiting for my new gas raku, lots of heat control with the gas.

Mike,
Thanks,
I just drew a very art deco shape demi-tasse the would work well...
mugs are tuff since we all like the feeling of our fave, why not lister who are interested post to Bens roasting site on Yahoo you favorite "mug shot" (I have mine) and we can all decide down the line what shapes we want.
Ben will post his site for me since I don't have it handy this second.

great idea but having them the correct size after firing is/would be the issue. 
that's the problem with hand done pieces.
you could have a couple of  "standard" sizes and get darn close.

Hi Group
I have read that the SCAA produces a series of color cards used to identify 
the deepness of your roast. My understanding is that these are really for 
comparative reference and not a strict grading value but none the less I 
decided that I wanted some. Unfortunately I don't see them offered any 
ware. I emailed the SCAA but haven't had a response. Does anyone know where 
these cards might be had? Assuming that I am remembering correctly and it 
was in fact the SCAA that produced them in the first place. And of course 
that they are still being produced.

I don't think pictures would do it.
First you have to specify what kind of light is on the tiles when they 
are being photographed.
If taken with a digital camera, there is always colour-balancing 
processing within the camera
How would you view the photo - if on your computer monitor, then it 
would have to be colour-matched to the camera.
If printed, there are the variables of printer, ink, and paper.
Nevertheless, if I had the tiles, I would send you a picture, but the 
prices are too rich for me.

Hi Group,
I too have been trying to get this color thing down. Everything
depends upon light, what kind of product the color is on etc. Dumb
question and this is for Tom as well. Would it be possible for Tom to
roast some beans to say six different roasts, divide them up into
smaller groups and sell the smaller groups to us? That way it does not
really matter what light because we would be able to compare the two
colors under the same light, it really wouldn't matter what kind of
bean as it would all be an average. Since the type of beans would not
really matter, it could the "s..t" beans Tom uses for samples of bad
beans. Would hate to see Lot 143 used. But all of us would be able to
see what it called a city roast, a city+ roast etc.
Tom I for one would be more than willing to purchase some samples of
the various roasts so that I could get mine more in the ball park.

Gin, probably not (maybe close). The tiles have a very specific 
pigmentation to take into account lighting temp, etc. In addition, they 
have a special glaze that you need to hald at a specifc angle to make it 
go away, to get the color right. How they make them was just in Roast 
magazine. FYI, the best issue ever.

Nice idea, but there is one glitch.  Coffee continues to darken with time.
The idea of a color standard is that it doesn't change over time.

21) From: john kahla
Good point Dan. Never thought about that. The thing is I really would
only need about two weeks with the samples before I had a pretty good
idea of where my roast was at. Also what would happen if they were
frozen after they arrive or if they were ground? Do they still change
color and if so how fast? Actually even swatches of paint samples from
the local hardware store would be ok if someone who knew the colors
picked them out. Am not trying to be a expert on color but as a newbie
would love to have a starting point that was even close.
John

22) From: Angelo
Whatever happened to the idea of using color swatches from a national brand 
paint company. Someone with a good eye for color matching could select the 
card numbers that correspond to the agtron tiles and we could all have a 
set just by going to the paint store and picking them out...
Seems simpler than going to all the work that is involved with making your 
own..

27) From: Zara Haimo
A couple of years ago, some kind person on this list sent several of us a
very useful set of paint chips that covered much of the range of the SCAA
color samples- can't remember who it was, sorry.  I used them for quite a
while to check my roasts.

28) From: Pecan Jim Gundlach
Dan,
        I was one who got the set of paint chips and I do appreciate the 
effort.  I compared my roasts with them but when it came time to talk 
about degree of roast, I knew most of the people on the list did not 
have them so I resorted to the old phrases such as "just before second 
crack" or "a few seconds into second crack" because I knew more people 
could understand it.

29) From: Pecan Jim Gundlach
If the glazes can be identified, how about a nice coffee mug finished 
with glazes to match different degrees of roast.  People could keep one 
or more of them handy.  Or, if the glazes are incompatible, a set of 
mugs with about six different degrees of roast.   Or maybe a plate with 
twelve degrees of roast at the different hours of the clock so owners 
of the plate could say something like "I took it to about 7:45", which 
would mean three quarters of the way to the 8:00 color past 7:00.
        Just stream of consciousness running here.

I think one of the problems with the "paint chip" approach to defining 
roast points is that, while it's based on the idea of the Agtron tiles, 
the Agtron tiles are meant to be used in a very specific way, using, as 
has been pointed out, ground coffee that is evenly spread, to a certain 
depth, in petri dishes -- I think there are other requirements as well 
but I don't recall what they are. While this may work fine for a single 
bean/blend roasted in a given roaster, I don't think it works well for 
comparing different coffees roasted in different roasters. And, it 
isn't intended to work at all for whole beans.
Of course, "just before second crack" or "a few seconds into second 
crack" aren't very precise either and give varying results with 
different coffees and different roasters. However, as Jim points out, 
at least for home roasters, it's a more universal language and doesn't 
require anyone to have special color tiles or chips or whatever and for 
everyone to use them in the same way to understand what is meant.

I agree, great ideas Jim. If some enterprising soul (Ginny) came up with a 
mug striped with varying degrees of roast I suspect some crazy people would 
even pay to have a set of them. (Like most people on this List I suspect, 
myself included;-) Might even be some established "online presence" 
interested in selling them on a regular basis, eh Tom!

I went back through my archived messages and found that I sent a message to the
list asking about color chips on Sep 16, 2002, and Dan had come up with them by
the 18th.  I was one of the ones he sent them to, and I still use them to log
every one of my roasts.  I'd still prefer that we use them on the list because,
though the system has its limitations and faults (what doesn't?), it still
conveys a lot of useful info that's hard to come by any other way.
So, for what it's worth, Dan, the set you sent me gets used every other day, and
I'm still very grateful to have it!

Gin, the clay does shrink when it is dried and then fired, but with 
practice you can get good at predicting the final outcome.
I do not pretend to be able to do this, but she has made tops to replace 
those that were broken in shipment for her casserole dishes.
Perhaps she will need to make a few tampers at a time and just pick the 
one that fits the best?

S-W is an industrial supplier. As such, they rarely change their colors,
only when they changed to a new paint formula did they have to reformulate
their colors.  Unlike home decorator and hardware stores, which change their
meager selection each year to match the annually published interior

You may have to fire the part with 'machine stock'. That is, extra large.
Then, use a post-process to reduce it to diameter. This would give you the
opportunity to produce a perfectly round tamper to the exact diameter.
i.e., grind it to shape.  Dan

There aren't actually any new numbers that are identical to the old 
numbers so, depending on the exact wording of your question, who reads 
it and maybe their mood that day, they may tell you just that.
However, the last time they changed their bases/colors, even though the 
old colors could not be duplicated exactly, they did have a formula to 
get as close as possible to the old color. (This seemed to consist 
mostly of adding some additional amount of black pigment. Touch up a 
spot in the middle of the wall and it obviously didn't match. Paint all 
the way to the corners and it was difficult to see the difference from 
the adjoining wall.)
So, they may have a list of what color you start with before you modify 
it to get something close to the old color.

John, This reminds me. The same thing happened when I wanted to remix a wall

finding new color chips.

61) From: Justin Marquez
With the computer color matching capabilities of most paint stores, if
we had some samples of known roast level coffees, we could probably
get paint mixed for the different roasts and make our own danged paint
chips.  The down side is that I think they will only custom mix a
minimum of a gallon.

I have gotten small paint samples from SW this afternoon and have not

also contacted the local store about getting larger ( 8x11 ) samples
and what they would cost.
I have talked to Tom and he is willing to take a look at the paint
samples and match them up as close as can be to the SCAA codes and
roast names. Thank you Tom !!!!
Then what I plan to do is list the numbers along with the information
from Tom so that if you want you can go to the paint store and make
your own kit or I will be putting kits together for those who do not

This is all a selfish motive as I want a kit. Will keep everyone

let me play with changing colors while displaying the Munsell HVC 
values along with the values of a few other systems of representing 
color.  My crude first estimate, using a laptop display, is 1.8Y 
1.7/4.1 for my image of Full City and 2.5Y 4.4/7.3 for Cinnamon I also 
ran across the following data base of ceramic glazes that includes 
Munsell values.

with it. I don't know if it is free or not, but those of you more 
knowledgeable about color and ceramic glazing might want to give it a 
look.
Does anyone know if Munsell values have been produced for the SCAA 
color tiles?
