Notes
*This adds titanium and red stain to the new fritted base of G2571B. Fabulous results. The amount of titanium in the previous test was too little high (losing a bit of the silky feel of the surface), this reduces it to 3%. This also increases the red stain from 5 to 6.
2000 water and 2000 powder worked well.
Mar 2023: Tests were done to dilute this up to 50:50. The diluted versions do give a better quality surface yet still have good color.

Notes
*The titanium/stain marbling mechanism works well in our G2571A cone 10 high-MgO silky matte glaze. But does it work at cone 6 in the G2934 MgO matte? That is what this investigates.
We are using a 90:10 matte:glossy mix to start. From prior experience, it seemed evident that more titanium would be needed o induce the effect, so we started with 4.5% (and 8% stain).
However, from the photo below it is clear that more titanium was needed, thus the 6% in this recipe.
