I like it! It seems like a lot of the ingredients and processes already exist (crushed bauxite exists) so there wouldn't be a need to add new items/material types, "just" the mechanics. Cooking the four glaze ingredients in a cooking pot makes sense to me, and storing the glaze in liquid containers/barrels like dyes makes sense. We already have the mechanic of dying cloth in barrels of dyes; seems to me applying glaze to a ceramic would use the same or a similar mechanic. I think most if not all of the items would need to be crushed using the pulverizer rather than the grindstone, based on what items currently require the pulverizer (like quartz and bauxite). This could be a viable way to add player recipes for the patterned storage vessels, flower pots, and planters that already exist in the game (currently must be bought from traders or found in ruins) {1.21.6}, meaning no need for new textures for each glaze (at least not right away). The ingredients needed are sufficiently difficult to acquire, relative to something like refractory bricks for the similarly advanced steel making, so it seems to scale pretty well with existing mechanics, especially with needing the pulverizer and perhaps high tier pounder caps. Making glazes in a cooking pot may even make the pot "residue covered" like candle making does, adding another level of planning.
