W-Make Recipe · Next

The workbench for recipes, raw materials and glass chemistry: calculate a recipe, compare versions and pass the result on as PDF, Excel or printout. Silos, shifts and production postings are not part of it.

Who it is for
For anyone who develops and checks recipes without having to open a shift.

Situation

Recipe work needs the same domain knowledge as production: raw materials, oxide calculation, redox, batch size, cost and versions. It does not need silos, shifts or live postings. Anyone at a desk who wants to change a recipe version, check the chemistry and print a batch sheet finds a full operations system cumbersome.

Put both into one product and production rules apply at the desk while drafts get the freedoms that do not belong in production. Drafts then end up in stock, or stock is rebuilt at the desk. Both cost time and cause mistakes.

Features

Recipes

Editor with live preview of oxide balance, cost and dry mass. Every save creates a version, and several versions can be compared side by side.

Target composition

You set an oxide target profile and the available raw materials, and the solver (NNLS) proposes the quantities. Tolerances can be set per oxide, and target profiles can be reused.

Viscosity and glass physics

T2, T4, Tg and liquidus after Lakatos, a Vogel-Fulcher-Tammann viscosity curve, and a comparison curve after Fluegel as a cross-check.

Redox and durability

Redox after Dietzel, hydrolytic class after Vogel, acid resistance to DIN 12116, and a plausibility check against a container-glass target profile.

Raw materials

Master data for purchased material, cullet and in-house material, with oxide analysis and scale rounding increments.

Output and extensions

Export as PDF, Excel and print. Optional modules include lab inbox, QA approval, SPC trend, lot traceability and SAP fields.

Walkthrough

What it looks like in the application

Recipe and oxide balance

As you change the weights, the preview recalculates cost, redox, working point and oxide balance. The result goes out as print, PDF or Excel.

Key decisions

  1. 01

    The same domain core for recipes, raw materials and glass chemistry as in W-Make Batch, without silos, shifts or live postings.

  2. 02

    Its own server, SQLite file and interface. Recipe does not depend on the operations product.

  3. 03

    Checking a recipe is a visible step. A calculation that runs unnoticed on save will not be found later.

  4. 04

    Batch sheets originate here as drafts and print templates. Posting happens in W-Make Batch.

The process at a glance.

  1. 01

    Recipes

    Version, compare, import and export, with reference to raw materials and cost.

  2. 02

    Materials

    Master data from which oxides and batch are calculated.

  3. 03

    Chemistry

    Oxides, redox and physics with a traceable calculation.

  4. 04

    Batch sheets

    Draft, scaling, preview and print-ready output.

  5. 05

    Check

    A separate step before a version counts as usable.

What carries over

Product boundaries are an architecture decision. A good tool does not have to model the neighbouring process in full, as long as it is clear where the handover happens.
