Hello everyone….
Granulating & Non-granulating.
– is there a magic word, secret sign, number, colour that is/isn’t granulated?
More than once I have been disappointed painting something to then find the colour is granulating. (or vice-versa) I paint in an expressive way, so can live with it most of the time, but would like to buy more colours and do not feel that I should without a little more understanding of this. I’m currently spending time on the handprint and Jane Blundell sites which are great – but I’d love to find the trick (if there is one) to selecting paint by granulation as well as all the other wonderful things I’ve learned via these sites.
I appreciate its all about pigments and all the rest of the techy info – but with a limited amount of time to apply to learning this I hoped someone could help me cut to the chase.
I would really like to include a broad selection of quality non-granulating colours for my next learning fortnight.
Even a suggestion of one colour that you use that is non granulating would be of great help
Can anyone help please?
Thank you
FayeAugust 29, 2014 at 1:06 pm #1210568The surest and most effective way to determine the characteristics of one’s paints (or paints one may wish to buy) is to simply check the paint manufacturer’s web site and look for the technical characteristics of the paints. Every reputable global paint manufacturer has a web site where the information is listed. The same information is also often found on the web sites of the major watercolor paint retailers, for each brand of paint sold.
Hope this helps.

It’s also listed on handprint.com which I would rely more on what it says about the pigments than particular brands. ( even thought quite a bit is still valid )
On that site, the GR column has 0-4 in it, 0 is not all, while 4 is heavily granulating. Then look at your tube and see the pigment code on it, does not have to even be listed as you can assume the pigment is similar. It tends to be the more finely ground staining colors. ( it’s hard to see the heading, it’s the column after the 2 digit “value range” column and just scan for zero’s )
I also rely on if it’s listed on that site as a top 40 pigment as an indicator of quality. Those are the ones that most here seem to mention the most.
Note that you might be better off with hot press paper, it has less texture and thus will tend to give you smoother color. You also might want to look at Gouache.
Thinking Pthalo blue PB15, pthalo green PG7 or PG36, PY154 winsor yellow, PO73 pyrole orange, PR254 pyrole red, PR179 perelene maroon, cadmiums, some quinacridones ( PR209 Quin Red, Quin Magenta ), Dioxazine violet PV23.

Blog: http://marciosart.blogspot.com/August 29, 2014 at 2:42 pm #1210577That’s a useful list of transparent colors. However, several granulate; opacity and granulation are mutually exclusive. Just like transparency can vary depending on how a pigment is processed, so can granulation. Best to check the manufacturer’s transparency and granulation rating for the exact tube you’re thinking of buying.
In general, but not as a rule: the “chemical-sounding” (synthetic organic) pigments are non-granulating, while the “mineral/earth” pigments are granulating (many are synthetic, too). A lot has to due with varied pigment particle size — something that tends to happen when roasting & grinding up rocks and minerals, but not when synthesizing a “pure” organic chemical pigment in a test tube (where pretty much all the molecules are identical, or in one of a couple chemical forms). Some pigment manufacturers are able to make granulating colors out of usually non-granulating pigments; this can be done with Phthalo blue to make a paint that behaves like the once-common (but toxic) Manganese Blue. Conversely, some of the “earth” pigments can be finely ground/filtered to a nearly-uniform size, removing most or all the granulation, and possibly making the paint more transparent in the process.
Some major pigment families that tend to granulate:
– Natural & synthetic earths (siennas, umbers), red/iron oxides, yellow ochres/oxides, various other iron forms (black/brown)
– Terre verte (natural green earth)
– Viridian
– Cobalt pigments
– Ultramarine pigments
– Manganese pigmentsConfused yet?!

August 29, 2014 at 2:46 pm #1210574Hi….
Virgil – thank you, I didn’t realise that they gave all the characteristics so that is really useful to know.
Brian – excellent, thanks… and thanks also for your list of suggestions. Really great to have a little shortcut list to checkout.
Marcio – wow, thank you so much for the lists… this is superb to refer back to without trying to work out what it all means.
shadoj – thanks for the advice and tips there… helpful and much appreciated.
I think I have my answers – thanks to the wonderful people here – as always, a great help and support.
Thank you all so much
Faye xxAugust 29, 2014 at 4:42 pm #1210578Missed some from a major group:
The chromium colors (including cerulean and potter’s pink) are granulating in general. Viridian, mentioned above, belongs to this same pigment family.Jen
August 29, 2014 at 5:15 pm #1210563Winsor & Newton has well organized info on transparent vs. opaque, granulating vs. non-granulating and staining vs. non-staining in their artist’s watercolor brochures which you might find at a nearby art shop.
August 29, 2014 at 6:47 pm #1210562Handprint is becoming very out of date. Bruce hasn’t updated his site in many years, so any changes in formulation or new pigments will not be addressed. He conducted his lightfast tests in 2004 and hasn’t tested anything since that time with the last updates in 2005.
It’s a shame because the site is a wealth of knowledge.
Dick Blick’s website offers some excellent pigment data for most manufacturers. You’ll have to visit Daniel Smith’s website for their information.

Cerulan Chromium (also a Chromium)
Cobalt TurquoiseUltramarines:

Undersea green (mixture)Variable:
Titanium Buff — varies in granulation by manufacturer, so check the tube/web/brochure!Jen
August 30, 2014 at 3:11 am #1210561Generally speaking transparent staining colours are non granulating because of the fine pigment particles.

We must leave our mark on this worldAugust 30, 2014 at 9:06 pm #1210571Here’s a paint-out I did for someone of a bunch of Granulating colours, just for reference.
Cheers, JaneAugust 30, 2014 at 9:21 pm #1210564Nice job, Jane! I must say I really enjoy working with the Daniel Smith Primatek paints and highly recommend them; can’t beat ’em for granulation.
