Glazecalc vs Repomix
A side-by-side look at the Glazecalc and Repomix MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Glazecalc for developer tools work over a hosted endpoint; choose Repomix for developer tools as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities
Glazecalc tools 33
search_materialsFinds ceramic raw materials (feldspars, clays, frits, fluxes) and, if asked, colorants in Glazecalc's library by name, alias or maker. Use it to find the exact name the other tools take.get_materialOne material from Glazecalc's library: its oxides, loss on ignition, whether it is discontinued and what replaces it, where it is sold, hazards and the data sheet it comes from.analyze_recipeWorks out a glaze recipe's unity (Seger) formula, oxide groups, silica to alumina ratio, fired analysis, loss on ignition and calculated thermal expansion, as the Glazecalc app does. stull says where the recipe sits on Stull's chart (1912, as the recipe page draws it): silica and alumina in moles, the region (unfused, matte, semi-matte, bright or underfired) and whether it falls in the crazed area; a guide to the surface, not a promise.check_limitsChecks a glaze recipe for what is past a recommended limit for its firing (too much boron or alkali, too little alumina, too little or too much clay, rising expansion...) and says what the fired glaze will likely do, as the Glazecalc app does. A cone is checked in the band the recipe page gives it (low cone 06-02, mid 1-7, high 8-11); from cone 12 up (band 'top') no published limits reach, so the band's limits are not checked and limitsNote says so. With a firing, coneFit says whether the chemistry looks like that firing's, by Katz's boron rule and Hesselberth & Roy's silica and alumina whatever limit set is chosen: verdict 'cooler' or 'hotter' only when boron and silica or alumina agree on another band; 'fits' (nothing points away, not a pass); 'skipped' where the published figures do not reach (lead, lithium, much soda and potash or zinc, raku, cones 01 to 3, cooler than cone 06 or hotter than cone 10...). Cone 6 against cone 10 is told apart only roughly (strength 'soft'). stull says where the recipe sits on Stull's chart, as analyze_recipe gives it. These are cautions and guides from published figures, not a test and not a guarantee of food safety.convert_cone_temperatureConverts between a pyrometric cone and its temperature, and between °C and °F. Orton cones run 022 to 42: Glazecalc's figure, from 022 to 15, is Orton's older chart for large cones at 150 °C an hour, and Orton's current figures (self-supporting cones at 15, 60 and 150 °C an hour, large cones at 60 and 150, cone 022 to 14) come beside it; Orton publishes no figure above cone 14, so cones from 16 up have none. SK cones (JIS R 8101, SK 022 to SK 20) by the standard's nominal figures. Give a cone, or a temperature to find the nearest cones.suggest_substitutesFinds the discontinued or scarce materials in a recipe and the modern ones that replace them, then suggests amounts that keep the unity formula as near as the materials allow, as the Glazecalc app does. report.closeness says how near the new unity formula comes to the old, oxide by oxide, as match_from_materials does. Test any suggestion before using it.match_from_materialsRemakes a glaze recipe from only the materials listed in "have", keeping its unity formula as near as they allow, as Match with what I have does in the Glazecalc app. report.closeness says how near the new unity formula comes to the old, oxide by oxide: close (within 0.02, or 5% of a large amount such as silica's), off, or far (more than three times that), with a verdict (close, fair or poor) and a summary. report.miss and report.best are the solver's own scores, for comparing runs. Raw clay is held to 20% of the batch where that costs the match little (report.capped and allowMore say more). Test any suggestion before using it.solve_targetMakes a glaze recipe, in percent, from the materials given whose unity formula comes as near a target as they allow (Solve for a target in the Glazecalc app). The target is a unity formula (moles; the fluxes are scaled to add up to 1) or an oxide analysis (percent by weight of the fired glaze), with potash and soda apart. Give the materials by their library names, or onHand for the materials on the person’s shelf (with a token or connected app that may read it). closeness says how near each oxide comes: close (within 0.02, or 5% of a large amount such as silica’s), off, or far (more than three times that), with a verdict (close, fair or poor) and a summary; unreachable names the target’s oxides nothing given supplies. Raw clay is held to 20% of the batch where that costs the match little (capped and allowMore say more). Test any recipe before using it.blend_recipesWorks out the test tiles of a line blend between recipes a and b (2 to 11 steps), or of a triaxial blend when c is given too (2 to 6 rows, up to 21 tiles), as the Blends page of the Glazecalc app does. Each tile is a mix of the corner recipes, each taken as a percent of its base: its shares, its recipe in percent, its key unity formula figures (silica, alumina, boron, the fluxes), silica to alumina, calculated expansion, its place on the Stull chart (stull), the names of the limit cautions it has, and, with a firing, whether its chemistry fits that firing (coneFit verdict). With two recipes and steps 2 it compares them oxide by oxide (differences). Give base materials only, no colorants. This is a calculation from published figures, not a test result: the tiles, fired, decide, and the cautions are guides, not a guarantee of food safety.vary_materialShows what one material does to a glaze, by putting more and more of it into a base recipe (an ingredient blend or progression test: whiting 0 to 20, say, in 2 to 11 tiles). With mode "add" (the default) it goes on top of the base, so the recipe grows; with mode "replace" the same amount comes out of another material of the base (`instead`), so the total stays the same. Each tile has its amount of the material, its recipe in percent, its key unity formula figures (silica, alumina, boron, the fluxes), silica to alumina, calculated expansion, its place on Stull's chart (stull: region, crazed), the names of the limit cautions it has, and, with a firing, whether its chemistry fits that firing (coneFit verdict). trend sums up what moves from the first tile to the last, and which Stull regions the tiles cross. Give base materials only, no colorants. This is a calculation from published figures, not a test result: the tiles, fired, decide, and the cautions are guides, not a guarantee of food safety.compare_recipesCompares two glaze recipes side by side: for each, its recipe in percent, key unity formula figures, silica to alumina, calculated expansion, place on Stull's chart (stull), the names of the limit cautions it has and, with a firing, whether its chemistry fits that firing (coneFit verdict); then what changes from A to B oxide by oxide (differences), and which materials are in A only, in B only, or in both, with their percents. It is the same comparison blend_recipes makes with two recipes and two steps, under a name that is easy to find. Give base materials only, no colorants. This is a calculation from published figures, not a test result: fire both, and the tiles decide.search_guidesSearches Glazecalc's plain-language guides for potters (glazing from first principles, making a glaze, safe mixing, safety at home with children and pets, firing a kiln, and a companion to John Britt's free glaze course, in English only) in the language asked for, or in English where that language has no match. Returns each matching section's title, anchor, a short excerpt, its address on the website and its resource URI, which resources/read returns in full. Use it for glaze defects, safety, firing and terms, and cite the address.- +21 more on the listing page
