SPECTRUM GLAZES:

SPECTRUM GLAZE Series: 1100 to 1192
Glaze Type: High Fire

GENERAL - We offer a selection of 77 cone 4/6 stoneware glazes. All of these glazes, except 1189 and 1190, are lead-free and dinnerware safe. Most of them also come with the A/P non-toxic rating from the Art & Creative Materials Institute (ACMI) which is clearly marked on the product label. Some of the reactive type glazes are rated C/L by the ACMI which means that they are considered toxic in the liquid (unfired) state due to the presence of heavy metals, such as copper, beyond the non-toxic legal limit. C/L rated glazes are not suitable for use by young children or pregnant women.

We have 3 types of stoneware glazes: clear glazes; plain colored glazes; and reactive glazes. These are described in more detail below. In general, clear glazes are used to cover designs created with underglazes. There is a choice of gloss, satin or crackle finishes. Our plain colored glazes are opaque and come in gloss and satin finishes. Some of our most popular stoneware glazes are the reactive colors which produce multi-tone and multi-colored effects by the combination of various metal oxides. Many other interesting effects can be created by layering these reactive glazes. In particular, layering a more fluid glaze, such as 1173, underneath or on top of one of the other reactive glazes often produces beautiful results.

All of our stoneware glazes are available wet in pints and gallons. They are also available dry in 10 lb. bags. The wet glazes are set up for brushing application. The dry glazes are set up for dipping application. For dry glaze mixing instructions see the sheet on "Dry Glaze Mixing Instructions" towards the end of this Product Guide. Please follow the instructions carefully especially with respect to the amount of water required.

CLEAR GLAZES

1100 - Clear Gloss Glaze (cone 4/6) - An excellent lead free, A/P non-toxic, dinnerware safe stoneware clear gloss glaze which is compatible with most commercially available underglazes. Like most clear glazes 1100 works best when applied thinly.

1120 - Clear Satin Glaze (cone 4/6) - Also lead free, A/P non-toxic and suitable for use over underglaze decoration. Satin clear glazes are not as translucent as clear gloss glazes and will tend to mute the appearance of underglaze decoration somewhat. It should be kept thin (i.e. 1 or 2 coats by brushing) to improve clarity.

1187 - Clear Crackle Glaze (cone 4/6) - A lead free, A/P non-toxic clear crackle glaze. After the piece has been removed from the kiln and allowed to cool the crackle pattern will form. A colored dye can be rubbed into the surface to emphasize the crackle pattern.

REACTIVE GLAZES

Reactive Glazes - 1113, 1115, 1117, 1129, 1140, 1141, 1142, 1143, 1144, 1145, 1155, 1156, 1162, 1170, 1171, 1174, 1175, 1176, 1177, 1178, 1179, 1180, 1181, 1182, 1183. - Are all lead free, non-toxic and dinnerware safe. They are formulated to produce reactions during the firing cycle which give very interesting and beautiful effects. The final appearance of the glaze is dependent on firing temperature, glaze thickness and the composition of the clay body being used. The same glaze can look quite different on different clay bodies. The samples shown on the color charts are 3 brush coats of glaze fired to cone 5 in an electric kiln on a white clay body. Different results should be expected in reduction.
