All of the pottery produced by Ray Pottery is handmade by the husband and wife team of Paul and Sheila Ray. It is either thrown on a potter's wheel, slab built or extruded. It is then fired in a propane fueled kiln to 2350 degrees Fahrenheit. Glazes are applied by a combination of dipping and spraying. Two of the stoneware glazes we use most commonly are:
Ash Glaze - Known for their subtle colors and mottled surface effects, ash glazes were some of the first glazes to be formulated by ancient Chinese potters. We use pine and oak ashes, collected from a wood burning kiln.
Copper Red - Copper red is achieved by adding a small amount of copper carbonate (usually .25% to .5%) along with tin oxide to a glaze and then firing it in a reducing atmosphere. Copper reds were first developed by Chinese potters over 1000 years ago and are still commonly referred to as "oxblood" glazes.
