A quick decision brief for this specific tool
Inputs that matter
One retained record/revision/recipe identifier/calculation timestamp and batch scope; one exact recipe source owner/locator and dry-weight basis note; 2–12 unique material names, current material identities and positive source weight parts that may total any positive value; ingredient evidence; one owner-selected positive target dry mass in explicit g/kg/avoirdupois oz/lb and a result unit; recipe owner, reviewer, review date and retention note; optional complete independent same-recipe weighed-mass record with one unit plus method/source/owner/identifier/time/same-basis evidence; and seven record/scope/basis/ingredient/target/comparison/decision boundaries
Output to expect
Normalized source proportions, exact target dry mass in grams and the selected result unit, grams per source part, per-material target masses, optional independent selected totals and signed per-material/total mass plus percentage-point differences, seven nondecisions and source-owned-dry-glaze-recipe-mass-reconciliation/v1 record
How it works
Normalize exact mass units with NIST-published factors; sum the retained dry source parts; calculate each source proportion = material parts ÷ total parts and each target material mass = owner-selected target dry mass × that proportion without intermediate rounding; when a complete independent same-recipe weighed record exists, normalize every selected mass and report signed selected-minus-target mass and selected-share-minus-source-share percentage points
Use only one retained dry recipe revision, one target batch and explicit current material identities. Drafts, mixed recipes/revisions/batches, wet slurry, volume/unknown bases, inferred or substituted identities, tool-selected targets and partial/different-recipe comparisons are refused.
The arithmetic does not calculate UMF, oxide/material analysis, LOI correction, chemical equivalence, water, slurry volume, specific gravity, viscosity, application thickness, coverage or firing behavior and never tells a user which value to adjust.
The result does not select or approve a formula/material/target; instruct mixing, handling, application, firing or kiln operation; prescribe silica controls/PPE/ventilation; certify fit, durability, leaching, food contact, quality, release, legal or regulatory status; merge the separate pottery recipe Tool; or create Project/scenario ownership.
Choose your path
Built around the job you need to finish
Normalize 2–12 explicitly identified dry-material weight parts from one retained glaze recipe revision, scale them to one owner-selected dry target mass, optionally compare one complete independent same-recipe weighed record, and refuse formulation, slurry, chemistry, process, firing, exposure-control, food-contact and compliance decisions.
Studio recipe owner scaling one retained test recipe
Scale a dry recipe whose weight parts do not necessarily total 100 without silently adding water, changing materials or pretending to solve glaze chemistry.
Identify one recipe revision and its current material identities, enter every dry weight part plus a 2.5 kg owner-selected target, choose grams for results, then review and export the exact normalized material masses.
Can trace each target mass to the retained part total while formula choice, slurry preparation, application, firing and fired performance remain outside the arithmetic.
Production documentation reviewer reconciling a balance log
Compare a complete independently recorded weighing set with the same recipe revision without receiving a hidden tolerance or correction instruction.
Enable the independent comparison, name its method/source/owner/identifier/time and same-basis evidence, append one selected mass to every ingredient line and inspect signed mass and percentage-point differences.
Gets reproducible descriptive differences and a portable record while adjustment, acceptance, quality release and regulatory decisions stay with accountable evidence and people.
Documentation-gap reviewer working on a phone
Stop wet, mixed, substituted, incomplete and unsafe requests before a new result can be mistaken for a mixing or food-safety instruction.
Exercise blank, example, arbitrary-total parts, duplicate identity, malformed line, partial comparison, invalid date/unit/mass, all seven refusal, stale-result, retained-record and Reset states in the source-defined responsive flow.
Can recover at the owning field and keep auditable dry-mass arithmetic without mistaking simulated paths for user research, laboratory analysis, industrial-hygiene advice or food-contact approval.
Authoritative checks for this tool
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
Keep one recipe identifier, revision, source owner and all current material identities together. Each amount is a dry-material weight part; the parts may total any positive value and are not silently forced to an assumed 100-part source.
Source share (%) = material parts ÷ sum of all source parts × 100
Scale only the owner-selected dry target
Normalize the explicitly labeled target mass to grams, multiply it by each retained source share without intermediate rounding, then display the same result in the chosen mass unit. This step does not add water or alter the recipe.
Target material mass = target dry mass × material parts ÷ total parts
Describe an independent weighing record
When every selected mass belongs to the same recipe revision and batch, the Tool can show signed selected-minus-target mass and selected-share-minus-source-share percentage points. It does not create a tolerance or tell anyone what to adjust.
Mass difference = selected mass − proportional target mass

Example Scenarios
A studio owner has one approved source record whose dry weight parts total 83, not 100. The Tool normalizes all retained lines and reproduces their proportional masses for the owner's 2.5 kg dry target without inventing a missing 17 parts.
A reviewer independently transcribes one selected mass for every material from the same recipe revision. The result reports per-line and total differences plus percentage-point differences, leaving acceptance and correction to the record owner.
A request combines old and new material lots, slurry volume and an inferred water percentage. The Tool refuses that scope instead of converting it into a dry recipe or claiming equivalent chemistry.
Common Mistakes to Avoid
✕
Scaling one percentage without the complete source denominator
✓
Retain every dry-material line from one recipe revision. The Tool must sum the entered source parts before it can reproduce any proportional target mass.
✕
Treating arithmetic agreement as formulation or process approval
✓
A matching total only reconciles recorded masses. Keep chemistry, material substitution, mixing, exposure controls, application, firing, testing, food contact and release with their accountable evidence and reviewers.
FAQ
No. Enter every retained dry-material weight part from one complete revision. The calculator sums the actual parts and derives each share from that denominator; it does not add, remove, or rebalance materials.
No. Target mass means dry materials only. Water, specific gravity, viscosity, application thickness, coverage and slurry volume require separate source-owned measurements and process decisions.
No. This Tool performs only mass normalization. It does not use oxide analyses, molecular weights, loss on ignition or a material contribution matrix, and it does not guarantee chemical equivalence.
No. Each line requires the current identity from the retained recipe. A substituted, inferred or mixed identity changes the evidence basis and must be evaluated outside this calculator before a new revision is recorded.
No. Mass agreement does not establish fired fit, durability, leaching, lead/cadmium compliance, food-contact suitability, firing adequacy, workplace exposure controls or quality release.
About Dry Glaze Recipe Mass Calculator
This calculator reproduces one retained dry glaze recipe as mass arithmetic. Enter every current material identity and its source weight parts, then apply one owner-selected dry target mass. The Tool normalizes totals that are not 100 and can describe a complete independent weighing record, but it does not formulate a glaze or decide how to mix, apply, fire, test, release, or use it.
