Notes

This is GR10-J dolomite matte (a Ravenscrag version of G2571A) with 1% iron oxide added (to produce a bamboo effect).

An alternative bamboo (for both this and the G2571A recipe) is to add 3.5% rutile and 10% zircopax.

Make cone 10R bamboo colors using the GR10-J Ravenscrag silky matte base recipe (right) and adding 1% iron (left), (0.5% centre). These samples are porcelain. This iron addition also works using the G2571A matte base recipe.

Two G2571A Bamboo versions: With iron, rutile-zircopax

These mugs are Plainsman H450 fired at cone 10R. Both have a black engobe (L3954N) applied to the insides and half way down the outside during leather hard stage (the insides are glazed with Ravenscrag silky matte and G1947U over the black engobe). The bamboo glazes can thus be seen over the black (upper half) and the raw buff body (lower). The bamboo glaze on the left has 1% iron added to the base G2571A recipe. The one on the right has 3.5% powdered rutile and 10% zircopax added.

The bamboo matte on the left is better:

It does not stain and does not craze.


A pottery mug has a glaze the stains easily

These mugs are Plainsman H443. The cone 10R dolomite matte bamboo glaze on the left (A) has 3.5% rutile and 10% Zircopax added to our base G2571A dolomite matte. The one on the right (B) has the same addition but in a base having less CaO/MgO and much more KNaO. This gives it a craze-prone calculated thermal expansion of 7.9 (vs 6.7 for ours). B also stains badly (as can be seen from the felt marker residue that could not be removed using lacquer thinner). Why does A stain only slightly? It has an additional 4% Gerstley Borate, a powerful flux that develops the glass surface better (giving a slightly less matte surface).
