Every figure it reports is computed by a stated formula from the measurements, prices and rates YOU enter, and every figure carries its UNIT. Grams and millilitres are never treated as interchangeable: wherever a mass becomes a volume or the reverse, the DENSITY used is printed beside the result and is yours to change. Every percentage names the quantity it is a percentage of at the point of use, because a rate on the wax is not a rate on the finished candle, a superfat is a reduction of the lye rather than an addition of oil, and a depth of shade is against the dry fibre rather than the bath. Saponification values, densities, shrinkage rates, cone references, thread factors, setts, feed rates, gauges and waste allowances are REFERENCE FIGURES that vary by supplier, batch and machine: each one is editable data, is shown beside the result it produced, and is a starting point to verify against your own supplier rather than a fact. Where a craft involves a caustic, a solvent, a kiln, a laser, a dye powder or a heat source, the hazard is stated where the calculation appears — this is a calculator and a record, not a safety authority, and it is no substitute for the manufacturer's and supplier's own safety data. It runs entirely in your browser with no network access of any kind and reports only what you recorded. It does not promise an outcome: not a successful firing, not a cured casting, not a safe or skin-safe batch, not a food-safe glaze, not a saleable piece.\u003c\/em\u003e\u003c\/p\u003e","brand":"Aceplore","offers":[{"title":"Personal","offer_id":52725946908812,"sku":"LEATHPERS","price":39.0,"currency_code":"CAD","in_stock":true},{"title":"Commercial","offer_id":52725946941580,"sku":"LEATHCOMM","price":79.0,"currency_code":"CAD","in_stock":true},{"title":"Extended","offer_id":52725946974348,"sku":"LEATHEXTE","price":149.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/3763\/9564\/files\/leatherwright-hide-yield-stitching--00-cover.png?v=1786995302","url":"https:\/\/aceplore.com\/products\/leatherwright-hide-yield-stitching","provider":"Aceplore","version":"1.0","type":"link"}
