Many people use the term "Methyl Cellulose" to refer to a wide range
of cellulose ethers and it is something of a misnomer.
The kind of cellulose ether generally used for marbling is a kind of
"surface treated" and therefore cold water-dispersible grade of
"HPMC" refers to all kinds of hydroxypropyl methylcellulose, the
majority of which are dispersed in hot water, not cold.

advanced search specifically targeting our group, you can get some of
the messages to come up.
