- As I posted a few days ago, last weekend I took a marbling workshop.
used methyl cellulose for our sizing. In the books I have on marbling
and from reading the posts from this group, most of you seem to use
carrageenan. In this class, the instructor said that after a few days
after being mixed with water the carrageenan spoils, but the methyl
cellulose is usable for months and months afterwards. So naturally I
can't help but wonder why anyone would choose to use carrageenan over
methyl cellulose. I figure there must be a very good and compelling
reason. Would you please share with me your choice of size and why.
