I would think the ants chewed up the dirt from below very well before depositing it at the top of the hill- hence the fineness.

I wanna see, too!

Hi - I'm new to posting here - have tried salt in acrylic - worked great but was heavy on the canvas - had a great lava like texture when it dried -

I have also used cutouts of acrylic painting on paper - cut out section that I liked and incorporated into an acrylic painting on canvas.

Also - crushed glass or polished stone.

You can also spray alcohol onto a thin acrylic wash and get nice raindrop effect - the paint has to be fairly thin

I look forward to getting more ideas here.

Two additives I have tried are talc and baking soda:
Talc can be difficult to mix in to prevent some clumping (unless you want this of course), but it does give an interesting subtle matt finish when the paint is dry.
Baking soda provides quite a bit of "tooth" or roughness to the dried film (particularly in thinner films) and is a lot less harsh on your brushes and palette knives than sand of a similar particle size.

You can also get a range of additives from Kremer including <A HREF=http://www.kremer-pigmente.de/intl.catalog/epigmen13.htm>mica and metal powders</A>, <A HREF=http://www.kremer-pigmente.de/intl.catalog/epigmen14.htm>fillers</A>, <A HREF=http://www.kremer-pigmente.de/intl.catalog/epigmen15.htm>extenders and thickening agents</A> that are definitely worth taking a look at.

Question Glycerin as a retarder: yes or no?

My first acrylics teacher suggested that we add ordinary drugstore glycerin to the paints on the palette to retard their drying, instead of the more expensive retarder. I used to use it with finity and it did make the paints kind of jelly-like, smoother to apply, and it did retard their drying on the palette.

My next acrylics teacher said that this was a bad practice, as the glycerin might be too acidic or in some other way affect the painting's archive-ability. So now I don't know what to do.

Does anyone know the right answer to this question?

Glycerin is gooey and permanently water-soluble. It is sometimes used in watercolors as a binder and drying retardant. I'm inclined to think that in large enough proportions glycerin would leave acrylic prone to resolubility, but a few drops in a large mass of paint shouldn't cause too much problem.

Propylene glycol is what is usually used in commercial acrylic drying retarder. I've never heard of glycerin being specified for this purpose.

PHB, glycerine is often recommended as a cheap retarder for acrylics and assuming you don't use too high a proportion I have not read any specific problems associated with it chemically.

From the Golden website "Humectants, agents that absorb or hold water (such as glycerin), also have been added to retard or slow drying. However, [they] must be used with extreme care as they tend to percolate to the surface of the film during drying, leaving a residue..." (I believe I have had this experience with a commercial liquid retarder). From another source "Rapid drying can be halted by adding [a] propriety retarder or by using pure glycerine with the paint."

As a rough guide use no more than 10% by volume but I would try to use less; you could try mixing the glycerine with water and using this mix to thin your paint, it might be a good way to keep the proportion down.

If you paint on canvas the Golden website has a really good tip that might be of use on their page about <A HREF=http://www.goldenpaints.com/drying.htm>drying</A> (see Soaking the Back of the Canvas near the bottom). There's a lot of other good info on this page also worth looking at.

Crushed up Mica adds an interesting effect.

I managed to download one to my hard disk but none of my graphics programs can open or view it although it does appear to be 'headered' correctly as a JPEG. How did you save the images?

Einion

P.S. How did you attach four of them?
