Re: [Marbling] marbling issues - white spots and sinking residue
- Hi Suzy,
I marble on fabric but the technique is the same . You shouldn't worry about the size getting dark. What matters is that the surface remains transparent. Yo can easily see this if you lower your head at tray level. The newspaper strip used to skim the surface must be the same width of the tray. Take the strip by each corner and starting at one end of the tray, slant the strip a little bit and skim al the way through. When you reach the opposite edge paste the strip to the tray wall and pull it up. Are you doing your marbling outside? That could add dust to the size. I do my marbling in my terrace and on windy days I get a little bit more dust than usual.
There is a DVD by Peggy Skycraft, Mastering Marbling that shows how to do this. www.dharmatrading.com has the best prize that I have seen so far. Hope this helps.

I am relatively new to marbling and have found reading these messages invaluable, so thanks to everyone! I am marbling on a carrageenan size using acrylic paints. Switching to golden fluid acrylics (as discussed in this group) has solved some problems I had with colour intensity and blotchy colours where the pigment wasn't mixing well.
I have two recurring problems which I am hoping someone may be able to offer me advice on:
1 - I keep getting tiny white spots on the finished image which I believe is due to dust on the size. How do I stop this, other than working extremely quickly once I've uncovered the size? I am also wondering whether the occasionaly tiny white spot is to be expected. I've got a sheet of marbled paper from a professional marbler which does have a few tiny spots on; admittedly it's a second but it has a large air bubble so I presume that's the reason for it being a second.
2 - When I clean the size I'm obviously not doing it right as I'm pushing some of the residue under the surface so that the size is becoming contaminated and so dark very quickly, after 1 sheet in fact. I've tried skimming lightly and putting newspaper down flat on the size but the trouble with this is that it takes quite a lot of the size with it and some still gets pushed under! This has only really been a problem since I started using the golden fluid acrylics, presumably because there's more pigment/stronger colour?
Hope to hear from anyone that may be able to help!
