Which one do you need?
- Resin Mold Volume & Mixing Calculator
- Turn mould dimensions into grams of casting resin and split the batch into Part A and Part B for any mix ratio, by weight or by volume, with cost per cast.
- Epoxy Coverage & Flood Coat Calculator
- Calculate the epoxy you need for a tabletop, bar top, river table or floor. Enter area and coating thickness for gallons, liters, lifts and material cost.
- Silicone Mold Making Material Calculator
- Work out silicone for a block mold by subtracting the master's displaced volume from the mold box, then convert to grams, pounds, base and catalyst.
- Candle Wax Calculator
- Work out how much wax and fragrance oil your candles need. Enter jar volume, fill level, wax density and fragrance load for per-candle and batch totals.
- Candle Fragrance Load Calculator
- Convert a target fragrance percentage into grams or ounces of oil per pound of wax, check it against the wax maximum, and cost the fragrance per candle.
- Soap Lye & Saponification Calculator
- Calculate exact NaOH or KOH and water for any cold process or liquid soap recipe from published SAP values, your superfat percent and lye concentration.
- Soap Mold Volume & Batch Size Calculator
- Size a cold process soap batch to your loaf, slab or cavity mold. Get mold volume, oil weight, total batter weight, bar count and a recipe scaling factor.
- Clay Shrinkage Calculator
- Measure drying and firing shrinkage from a test bar, then find how large to throw or build a piece so it fires to the finished size you want.
