These glazes are made from Ravenscrag Slip, this color is often referenced "Oatmeal". I add iron oxide to get the effect on the left. Then I add lithium carbonate to get the one on the right, that is the G3933G1 recipe.
Left is G3933A, it is an 80:20 mix of our matte and glossy cone 6 base recipes (plus a mix of iron oxide, tin oxide and rutile). The body is Plainsman Coffee Clay. Because of repeated issues with crawling a project was started to create the same effect using Alberta Slip to supply as much of the chemistry as possible. Along that road, the opportunity arose to add lithium (to duplicate Amaco PC-32, a classic Albany/Lithium recipe). That is the glaze on the mug on the right, G3933G1, it has 6% lithium carbonate. Lithium is a super powerful melter, turning this into a very reactive glaze! In 2023 a 500ml jar of this glaze required about $7 worth of lithium carbonate. That makes this an ideal candidate to prepare as a brushing glaze - a benefit of that is better control of thickness, a key to the visual effect this gives.
