*L3685U is a product of work done to match a white engobe to a vitreous fritted cone 03 red stoneware. However that slip is too vitreous for standard Terrastone 2 (which is not a vitreous body).
The first trial to adjust it for Terrastone 2, L3685X, is not dry shrinking enough and fire shrinking too much. This mix, Y, adds more bentonite and subs 5 frit for nepheline.

G glaze.

No hint of shivering on side of mug, but rim on one. However the slip is very thick on the rim, maybe this is part of the reason.
