I've been practicing a lot recently on different sizes (undisclosed
ingredients from seller).
Finally after much searching around, I found some carrageenan in a big
company lab. I just don't know how concentrated the powder is. After
mixing 30 gr. per gallon, it is much more liquid than other sizes I have
used. It is about the consistency of light cream.
I use premixed paints and acrylics I mix myself (which seem to work ok
Funnily I had to put some ox gall into my Pebeo yellow because it would
just sink! I also found that not all pre-mixed colours from a provider
work the same.
I have also tried to marble on white wallpaper sheets (the one with
little bits in it called ingrain in French) and it worked well. Besides
it was very interesting because I could cut the sheets to the exact size
of the tray (it always annoys me when some of a nice pattern has to be
left behind for waste).
Should I leave the carrageenan until tomorrow? Will it continue to
thicken? How should it be? Can the consistency vary depending on the
temperature you will use it etc.. or is it invariably the same?
Thank you for your advice.
Have a great weekend.
