FOG Tuesday – We’ve Found Our Marbles

At the April session of FOG we found out just how easy it is to marble on fabric and paper, both having the same prep for a wonderful result.

We tried two different methods of marbling, one using a thickened medium in our trays and the other using foam shaving cream. It needs to be the foamy kind, not gel, to work. NOTE: It is helpful to know some basic colour theory to understand how your colours will mix.

Prep for the first technique. Thickened Carrageenan or MarbleThix

Using carrageenan (available at art or health food stores) or MarbleThix™ by Delta, mix the quantity of dried product to warm water, MarbleThix™ used one TSP of powder to one quart of water. This is best done at least 6 – 12 hours before using. MarbleThix™ is the one that I used. Some did this in a blender; I just did mine by hand in a container. Unfortunately, MarbleThix may no longer be available. We purchased ours from a local dollar store

The second step for prep is to mix up an alum mixture to soak your fabrics and papers. Alum helps the colour to adhere to your product and improve on print quality. Fabric should be soaked in 2 TB of Alum dissolved in 1 quart of water. Paper should use more Alum - 4 TB in 1 quart of water.  Both items need to be dipped in the solution and then dried before marbling. Alum may be purchased in a health food store or in the spice department at your local grocery store.

Both alum and carrageenan are used in the production of food products so are very safe for use, even for children.

Lastly, you need to choose the type of inks, dyes or paints that you will use to float on the thickened mixture in your trays. We found what best worked for us by trial and error. We tried alcohol inks, different qualities and brands of acrylic paints, Liquitex Acrylic Ink and Dye-na-Flow™ by Jacquard.

I tried alcohol inks that sank to the bottom right away. I did not try acrylic paint and found that my best results were with Dye-na-Flow™. It is used on both natural or synthetic fabrics and papers.

Now comes the fun part.

Pour your thickened mixture into a tray. The mixture should be clear in colour. Start by dropping your colour onto the surface – making blobs of colour and then dropping additional colours into that blob, giving some interesting results.

Next, drag a skewer or other tools through the blobs and your pattern starts to appear. Once you are satisfied with the results, place your dry, alum soaked fabric or paper onto the surface of the newly coloured mixture. With fabric, it helps to hold the two sides and drop in the centre of the fabric first, then the sides. Lightly pat the surface of your fabric or paper trying to get all the colour on the surface to adhere.

Once that is done, carefully pick up your piece from the surface and put aside to dry. If there is any colour left on the surface, run a piece of paper over it, leaving it clean to do your next design.

Prep for the second technique. Shaving Foam

Spray the foam shaving cream onto your surface or tray and drag a straight edge across the surface to create a smooth even surface. (If anyone has found an unscented shaving foam, please share the brand name with us.)

Next drop your colour onto the surface of the foam and drag a skewer or other tool through your drops of colour to create your pattern. Once you are satisfied, place your fabric or paper onto the surface, tap it down and then pull your print. Lay the print on a solid surface and using a straight edge, drag the remaining shaving foam from your print.

Inexpensive acrylic paint, food colouring and inks are three good products to use on the foam. The foam can be reused several times, however, if colour is left on the foam it may affect subsequent colours that are layered on top.

Have fun with this, it is quite addictive. I’m certainly ready to make additional pieces and have purchased a larger foil tray to that I can do some larger pieces.

Fruits of our labour.

As always, we enjoy your feedback. Cheers, Meredith and Jan
