Most of the work in marbling is getting set up, but once you are all set up you can play for hours!
Making a frame
If you are working with fabric or clothing larger than your available pans, it's easy to build a pan using some 1" x 4" wood. Nail together a frame without top or bottom and just line it with some heavy plastic. You can make the frame any size you need.
How much size do I need?
Preparing the "size"
Carrageen (Blender type): make 24 hours before it is going to be used.
Use 2 tsp per 4 cups of warm water, slowly add to the water through top hole in blender lid. Blend until it's fully dissolved, make as many batches as you need to fill your tray or frame.
Refrigerate for 24 hours to obtain the best viscosity and to allow trapped air bubbles to rise to the surface.
Before use it needs to be warmed to room temperature.
Methocel: can be made 30 min before use
Use 4 tblsp of Methocel and 1 tblsp of ammonia per gallon of warm water
In a bucket, add ammonia to the water and then slowly add Methocel, stirring constantly with a whisk or large spoon.
Pro-tip: Dont use the blender or it will foam up and have to sit over night, ask us how we know!
Stir until the Methocel is dissolved and appears clear, let sit for 30 min for bubbles to rise.
How thick the "size" needs to be will vary with the brand of paint being used and the effects you like best.
Pro-Tip: We found doubling the Methocel recipe above kept most paints from sinking and gave us neat spreading patterns with the thinner paints.
Fill your pan or frame with the size, and just before adding the paints, skim off any film that has formed on the surface of the "size" by dragging a strip of newspaper from one end to the other.
Hard water:If the water in your area is "hard" (contains lots of minerals) you will need to add some of our Water Softener. Hard water will interfere with the process.
Reusing the size
The "size" can be used over and over again. It can be kept for 3 to 4 days at room temperature before it begins to mold and must be discarded. To keep it longer, refrigerate. (Mark and tape the container clearly so it is not eaten.) Warm it to room temperature before using. If the "size" has been sitting awhile, clear the surface of tension and dust with strips of newspaper before using.
Preparing the fabric
Pre-wash the fabric with Synthrapol or regular fabric detergent and dry. This will wash out anything that is likely to prevent the paint from sticking.
Dissolve 3 TBS of Alum per quart of hot water. Cool to room temperature. Dip the fabric into the alum solution or if necessary, such as for paper, sponge it on very thoroughly. Lay it out flat to air dry. The fabric must be treated and must be dry before it is marbled. It is best to use the treated pieces within 24 hours. If you can't, then wash out the alum and try again another time. Careful! Too much or too long rots the fabric!
Iron the fabric on low briefly if needed to remove large wrinkles, but not too hot or too long as alum and heat can rot the fabric. Small wrinkles will not effect the print.
Now Let's Get Started!
Floating the paints
You may need to thin some paints before they will float. Use a few drops of Dispersant and a little water to thin them to the consistency of whole milk in a paper cup or one of the Color Mixing Cups.
With an eye dropper, lay the paint on the surface of the "size" as gently as possible. The drop should spread out to a circle 2-3 in size. As the paint spreads out on the surface some may sink to the bottom - it's ok as long as most of it stays on the surface. If too much seems to be sinking, thin the paint a bit more. If the drop spreads out too far, thicken the paint by adding a bit from the bottle. Keep adding paint to the surface until they seem intense or you are happy with the proportion of the colors.
The order in which you drop the paints directly affects the look of the finished piece. As you add new colors, the ones added previously will intensify as they are pushed together. You can add new colors next to, or on top of, the ones already there. Some paints will spread faster and push others out of the way more, you should keep notes if you want to repeat effects. The colors don't mix, but rather stay separate. You can remove the paint and start over by laying newspaper on the surface to pick up all the paint from the surface.
Pro-tip: Making a small side frame of size for testing your paint consistency can help you get clear how your paints will act before 'going for it'!
Making the designs
Anything goes when it comes to making your designs, in fact that's a main part of the fun.
Going back and forth with a toothpick or chopstick will produce chevron patterns.
Using a wide spaced comb or sort of rake in one-direction gives an interesting series of rounded, repeating shapes.
Using a skewer to make series of spirals will result in a "snail motif."
Dip a whisk or a bundle of broom straws in some paint and flick drops onto the surface.
Create "negative" areas in the design by placing soapy water on the surface with an eye dropper or by sprinkling it on. Use 1/8 teaspoon of liquid soap to 1/2 cup of water. Use this like a "clear paint" in your designs
Applying the paints to your fabric
Lay the middle of the fabric down first and let the ends roll out onto the surface so no air is trapped underneath. Leave the fabric down for 2-5 seconds before lifting it off. Try to "peel" the fabric off the surface so it doesnt fold onto itself.
Dash to the sink or have a bucket handy and gently rinse with cold water to remove the alum and excess size. Now lay flat or hang to air dry. Don't wring or squeeze as the paint will not be 100% set until it has dried and been ironed.
When the item is completely dry, heat set according to the heat setting instructions for the brand of paints you are using.
If you are doing two-sided items like T-shirts, cut a piece of cardboard to size and cover with plastic or Saran wrap and insert into the shirt. Do one side, re-do the colors and then do the other side.
After each "printing" you can either add more paint or clear the surface with newspaper and start a new design.
Other examples we did:
Skim the surface of the marbling base with a strip of newspaper. If you're planning to reuse it soon, cover the paint mixture with plastic wrap or airtight lids. The size is usually good for more than one session.
If youre not using your size again pour it down the toilet or run lots of hot water with it down the drain to avoid clogs.
Rinse the marbling tools in lukewarm water without soap. Soap residue on tools can contaminate future prints.
Rinse the tray thoroughly in a sink. Again, do not use soap.
The marbling paints sink to the bottom of the tray.
The size might be too thin or old. Add 1 teaspoon of Methocel (Methocelulose) powder per gallon of solution, or throw out and start a new recipe.
Marbling colors are too thick. Add water to thin the colors, skim the marbling base, then test. You may need to add Synthrapol to the paints to improve its ability to spread and float.
The marbling colors spread too much or not at all.
You might have added too much water or surfactant to the marbling color. Add more paint to balance it out.
Size maybe too thick causing the drop to just sit on the surface. Add water to the size to thin it out. Skim, then re-apply marbling colors. Experiment with it to achieve the desired effect.
The marbled print appears fuzzy.
The marbling base is too thick. Add water to the size, then re-apply paints.
The marbling colors might be too thick. Thin the colors with water, then test.
There was too much time spent between making the pattern and putting the fabric in the paint mixture. Work more quickly.
The most frequent disaster is that the fabric falls apart at the end. It's from the Alum. Make sure you are not using more alum then recommended and use your fabric right away or wash it out.
As you may have surmised by now, marbling can be a messy project, one which is best done with enough space to spread things out, and with lots of newspapers on hand. It's a great outdoor project when weather permits! However, the results are unique and spectacular!
THIS IS NOT THE WHOLE STORY!
This is just a quick introduction to the topic. There's a lot more to say and to know. We have a good DVD on the subject that goes into detail and can help you get good results.
Things you might need:
Rakes, combs, implements for pulling the paint:
