If you glaze fired to a hotter temperature than the bisque, it is possible that more carbon would burn out during glaze firing, causing blisters in the glaze which would not have time to heal over. For some clays this is not a problem. The carbon content in the clay is low or burns out early.
Catecholamines are derived from the amino acid tyrosine, which is derived from dietary sources as well as synthesis of phenylalanine. Catecholamines are water-soluble and are 50%-bound to plasma proteins in circulation.
Salicylates are one type of phenol in the phenol family and scientists believe they are produced by plants for use as their own natural protection from diseases, insects, fungi, and harmful bacteria.They are made up of a phenol compound with an additional COOH group (more science talk about how it is put together).As it turns out, salicylates are chemically very similar to the man-made chemical acetylsalicylic acid, more commonly known as Aspirin.n a normal body, one with the correct levels of sulfates and liver enzymes, phenols and salicylates are easily metabolized. The body utilizes what it needs from the chemicals and properly disposes of the rest through the bowels.
