Affectionately known to some as "methy," methyl-cellulose is a commercial thickener. It is created from the cellulose found naturally in vegetables
. This safe, virtually-odorless, tasteless white powder, even when mixed in small amounts, will efficiently thicken a large volume of water. Used as a base, it is a very cost-effective way to make a large amount of clear gel. It stays thick when heated, and will store for long periods of time without any preservative.
