900 Series Low Stone Glazes Pottery can have a stoneware finish with Spectrum 900 Series Low Fire
Low Stone Glazes. These glazes vary in shade, style, and use, but all
are lead-free and dinnerware safe when fired to the appropriate
temperature. Forty-seven of the Spectrum Low Fire Low Stone Glazes are
certified A/P certified non-toxic by the Art and Creative Materials
Institute. The remaining 16 are also dinnerware safe, but should not be
used by young children or pregnant women due to high levels of copper
oxide or nickel oxide.
These glazes are available in two-tone gloss with either satin, speckled, or metallic finishes.
Our exciting line of low fire (cone 06/04) glazes that give the appearance of a stoneware finish.

We have included 900 Clear in this line which can be used, for example,
to line the inside of pots. Please do not use our 900 series glazes on
the same piece with our 700 series glazes. Due to significantly
different expansion rates this combination can cause pots to crack.
In addition to the chip samples in our color chart which show the result
of applying 3 coats of each glaze on white bisque and firing to cone
05, please also look at the bell samples on our poster which show
examples of some of the wonderful effects that can be created by
layering these glazes. These bells were done by putting 2 light coats of
one of the Low Stone glazes on the top half of the bell and then
applying 2 normal coats of one of the other Low Stone glazes over the
entire bell. We only had space to show a few of the numerous possible
results that can be achieved this way.
All of these glazes are lead-free and dinnerware safe when fired
correctly. 47 of the colors are AP non-toxic, but 16 of the colors
Health Labels for use in the unfired state. This is due to the presence
of copper oxide and/or nickel oxide exceeding the prescribed limits.
