Cmc Gum Ceramics
They slow the drying time allowing for more movement of the glaze before it soaks into the bisque fired pot and reduce the surface tension of the glaze so that it s more willing to flow rather than just stick to itself.
Cmc gum ceramics. Finnfix cmc sodium carboxymethyl cellulose and kelzan xanthan gum are well known additives in different segments of the ceramic industry. Since the hydrophilic groups are not uniform in the production of cmc then the dispersed particle sizes of micelles are inconsistent. When water penetrates inside the cmc gum blocks the part with less hydrophilic groups will produce swelling while the part with more hydrophilic groups will immediately separate from gum blocks after swelling. Gums are used in ceramics to harden unfired ceramic glazes.
Quantity discounts are available. Cmc gum also reduces drying shrinkage and enables multi layering without flaking or cracking. An organic cellulose gum which functio. Normally a small amount of gum is added to a quart or so of warm water and left overnight.
Carboxy methyl cellulose c m c powder. Blend this mixture very well allow it to stand for a day then blend again. The viscosifying plasticizing and suspending properties of these products make them ideal ingredients for consistent predictable performance. Cmc gum carboxymethylcellulose cmc an organic gum used as a suspension adhesion agent in glazes.
This makes for safer handling of ware better adherence to the body slower drying thus better brushability. Cellulose gum has been used in food products for over 50 years as a thickener and stabilizer. Cellulose gum carboxymethyl cellulose cmc or cellulose gum is an abundant and natural polysaccharide found in all plants. Add 50 grams of the dry gum to one liter a bit less than a quart of very hot water in a blender reserved for studio use.
Cellulose gum is a water soluble gum that is based on cellulose. Carboxymethylcellulose cmc gum is used to thicken and stabilize materialsit is a nontoxic food grade additive that is seen in ice cream toothpaste diet pills and even personal lubricants it is used in ceramics to harden unfired ceramic glazes it is also a helpful addition to stain mixes that are applied over glaze by stamping or painting a small amount of gum is added to a quart of warm. Cmc gum apt ii spectrum brushing media and magma all improved the glaze s brushability.
