Re: Grainy paints / What do you use?

I use mostly Golden Fluid Acrylics and Jacquard Air Brush colors, on a methylcel vat. I have noticed that black slides off easier than other colors, also red. I assume it is a characteristic of those particular colors. Each color is a tiny bit different chemically. I mix Jacquard Air Brush black wit...

Re: Regarding allum.

Alum solution, when it dries, leaves a very fine crystalline powder behind. This is normal. The whole point of putting alum solution on the paper is to get a very fine layer of tiny crystals deposited there. The alum kind of grabs the pigment and holds on to it. As you have probably found, the pigme...

Re: Are the 'off-the-shelf' marbling inks any good or are they snake oil?

Some are OK, some not. Sorry to say, differences in water, conditions, types of size, etc. make every studio situation a bit of a mystery.....and definitely, one type of marbling ink does not fit all. You just have to try stuff. Most of the ones I have tried float too well. But I have no way of tell...

Re: If I am adding several layers on top of my marbling, do I need to re-apply allum?

Yes, I would do the acrylic layer last. Some other artists are able to do several layers of acrylic. It might be a combination of the paper and the brand of acrylic. I have done pieces with the first layer of acrylic thinned a lot, so it didn't cover the paper fibers completely. The second layer stu...

Re: methocellulose, carrageenan and ammonia.

Yes, it is necessary to use the ammonia with methylcellulose. Left overnight without the ammonia, the container appears to have a rubbery hockey puck at the bottom in the morning. When initially mixing the water and methocell, I stir until the solution is fairly clear (lots of stirring at first, the...

Re: How far in advance do you alum your papers?

I apply alum, dry, and iron the paper. Have used these papers up to a couple of months later. However, I have noticed that papers which have alum applied several weeks previously tend to get brittle. I assume the paper is breaking down. Alum will degrade cellulose over time. This is very noticeable ...

Re: If I am adding several layers on top of my marbling, do I need to re-apply allum?

Yes, alum needs to be carefully re-applied after previous layer has been rinsed and dried well. Acrylic paints dry with a kind of plastic finish. Once they are dry, more acrylic will not stick. The second time around, do the alum thing and proceed. But the second marbling will stick only to the pap...

buffered paper

I have read that buffering on paper interferes with color attachment to the paper. Does anyone have thought on this?

Re: Paper

Sulfite papers (all wood pulp) are too tender to stand up to all the wet-and-dry, unless they are more than 90 to 100# in weight. Paper which is good for printmaking is usually pretty good for marbling. These papers are usually all cotton, tend to have one 'toothy' side and be somewhat absorbent. Th...
