I would only do a day's worth of marbling on the sodium alginate...it would
start to break down after about 50 sheets. I have no idea as to the cost
comparison to carraghean, but I don't think it is any less expensive...its
been too many years since I've used it, and only used it for oil paint

Yes, the days of boiling and straining were messy. If anyone out there is
still doing it, the best strainer is to go to a paint store and get a bag
that is used for straining paint...works a lot better than panty hose (which
would break and you'd have to start all over!). I only had one boil over
and that was a nightmare.
