Meltpool vs Waft

The candle maker's calculator that gets the math right — in ounces AND grams. Meltpool gives container-candle and wax-melt makers six precise, bench-ready calculators for free, and keeps your whole catalogue priced, stocked and repeatable with Pro. EVERY NUMBER YOU NEED AT THE POUR STATION • Container Fill — water method (water weight × your wax's factor) or vessel dimensions → exact wax weight per candle and per batch, with purchasing totals and a burn-time estimate. • Fragrance Load — set your FO percentage and see fragrance weight and total pour instantly, with each wax's typical maximum marked. The convention is stated right on screen: FO % is of wax weight; total pour = wax + FO. • Batch Scaler — scale any recipe to N candles or a target weight; wax, fragrance and dye scale together. • Candle Pricing — editable cost lines (wax, fragrance, wick, vessel, label — rename them to match your supplies), labor and overhead → unit cost, then wholesale and retail with honest margins. • Wick Size Guide — vessel diameter → size-class guidance, the double-wick rule, and the full melt-pool check so you always burn-test with confidence. • Dye & Colorant — percentages or per-pound dosing without the spreadsheet. OUNCES AND GRAMS, FIRST-CLASS One global setting. Every value in clean monospaced figures. Pounds and kilograms appear as purchasing summaries — rounded up, so you never under-buy. No screen ever mixes systems. SHOWS THE WORK Every result card shows how it was computed — the water factor, the wax:FO split, the cost lines, the rounding. Check it against your own math any time. That's the point. YOUR RECIPE CATALOGUE (PRO) Save any calculation into a recipe — large candle, small candle, tea light. Each recipe keeps its vessel, wax, fragrance load and wick notes, rolls every saved calculation into a bill of materials, and prices the candle with your real costs. Export a clean material list for the bench or your supplier, and print a retail price list for a craft fair or a wholesale line sheet for a shop buyer. YOUR STOCK ROOM (PRO) Track every material you own — wax, fragrance, wicks, jars, dye, packaging — with what's on hand and what each costs, plus a low-stock heads-up before a pour run. Link a recipe's cost lines to your stock and every candle prices itself from your real unit costs — change a price once and every recipe updates. Poured a batch? "Made a batch" counts your stock down automatically, with shortfall and low-stock flags. Free saves one recipe; Meltpool Pro unlocks recipe pricing, the unlimited catalogue, the stock room, PDFs and export. PRIVATE BY DESIGN No account. No ads. No tracking. Works completely offline.
