Safety:
    Due to changes in safety standards and raw materials that are used to manufacture the products, the information on the website is considered a general guide and is not the final authority regarding toxicity and dinnerware safety.  Always refer to the specific product label for complete toxicity and dinnerware safety information.
    Spectrum clearly identifies their few glazes that contain lead through the use of a BLACK label and appropriate safety information on the label.  Appropriate safety precautions should be taken when using a lead based glaze and these glazes should never be used by children, women who are pregnant or may be considering becoming pregnant, or people with other health issues.
    There are a few Spectrum glazes that are listed as being toxic in the premixed liquid form.  These glazes typically contain excessive levels of soluble copper or other metals and while the finished product may be dinnerware safe, the liquid glaze should only be used with appropriate safety precautions, and children, women who are pregnant or may be considering becoming pregnant, or people with other health issues should avoid using these glazes.

Performance:
    Spectrum's products were designed for use with moist clay body, and all firing information within this website and on the product labels is specifically applicable to moist clay.  If you use Spectrum's products with cast slip, such as Mackie's Slip or Seeley's Stoneware Slip, a small change in the firing temperatures of the glaze may be required to meet the technical specifications of the slip.
    The digital sample pictures within this website show the product fired on a white, nearly flat, horizontally fired, tile that was fired to the appropriate cone.  With the exception of the Raku glazes, all products were fired in oxidation (electric kiln).  The digital picture is the best means of showcasing the results that may be obtained with each product, however, due to variances in computer displays, ambient lighting conditions and other factors, the digital pictures should only be considered an approximation of the results that may be obtained.  The use of a clay other than white may dramatically affect the color that is obtained, especially with lighter colored glazes and underglazes.
