Liquid Brushing Directions
DIRECTIONS: Shake well before use. Thin with water and AMACO® Gum Solution if needed. Apply 3 coats of glaze to Cone 04 bisque. (Let the glaze dry between coats.) Glaze fire to Cone 5-6.
Ancient Jasper benefits from a heavier application—it needs thickness to promote the floating of the iron. This glaze will produce reds on all clay bodies, although iron bearing clay bodies will produce the widest range of float colors. No special cooling cycles or soaks are needed. (Soaking will actually diminish the reds.) This glaze is also great to use when layering with other AMACO® Potter’s Choice glazes.
PC-53 Ancient Jasper exudes the beauty and tones of ancient rock. Deep red tones, purples, yellows, browns, and black all intermingle in this glaze. Textural pieces allow Ancient Jasper to break up into a rainbow of rich tones which look like a combination of many different glazes.
Dry Dipping Directions and Warning
MIXING INSTRUCTIONS: Do not produce dust. Wear a NIOSH approved mask for dust or mist. Do not empty glaze powder into another container. Add water gradually into the bucket, stirring slowly. The glaze level will drop in the bucket as you mix in the water, allowing for more water additions until a creamy consistency is achieved. To insure a homogenous mixture, use a glaze mixer attached to a hand drill. Mix for at least half an hour. Although every glaze formula will have its own special water requirements, a basic recipe is to add 3 1/3 gallons of water to 25 pounds of dry glaze. Add a little more water if needed. One pound of AMACO® dry glaze will make approximately one pint of liquid glaze. Try not to let the glaze become thinner than needed, since the lower the viscosity, the greater the chance that heavy glaze particles will settle out. AMACO® glazes have a sufficient suspending agent to prevent settling unless an excessive amount of water is added. Store prepared glazes in their own airtight buckets.
DIRECTIONS: Stir well before using. If it is too thick, add some water very cautiously until it has the consistency of thin cream (dipping consistency). Dip the Cone 04 (1940°F, 1060°C) bisque fired piece into the glaze, lift it out and turn it over, allowing the excess glaze to pour out. The glaze will stop running as soon as it is lifted out of the bucket. Application is uniform and there is no waiting for it to drip or dry. Fire to witness Cone 5-6.
Request Material Safety Data Sheets when using in manufacturing. Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
WARNING: This product contains a material known to the State of California to cause cancer.
PC-53 Ancient Jasper is an “Artistic Float Glaze”. These glazes need a certain thickness to float materials to the top surface of the glaze. This creates interest where the glaze pools in texture or drips. (If the glaze is applied too thinly, the glaze will not be able to float. The end result will be flat and probably an incorrect color) The tiles show the float developing as the glaze is applied more heavily. Float makes these glazes perfect for layering.
