Meltline plans an ice dye by how each Procion dye splits, runs the dye calculator for powder and soda ash, times the batch and turns the result into a recipe card. Free, offline, no account required.
Free. No IAP, no paywall.
From the split chart to the muck, Meltline follows the batch from plan to recipe card.
A dye calculator alone cannot tell you what a blend will look like on cotton. Meltline can.
Every color marked pure or blend, and for each blend the bands it throws. Filter the library by behavior: dyes that throw a magenta, pure blues that will not surprise you.
Place your dyes on the folded bundle and Meltline flags the boundaries where two splits will meet as complements and go brown, before you commit the fabric.
Dry weight of fabric to grams of Procion powder at a chosen depth of shade, plus soda ash, urea, water and ice. The per-color strength multiplier is applied automatically.
Photo, fabric, fold, ice ratio and batch hours in one record. A cure timer with the ambient temperature beside it, because Procion stalls below about 70°F.
One tap turns a logged batch into a shareable card: the finished piece, the dye list with amounts, the fold, the ice ratio and the batch time. The answer to "recipe please".
Clone a past batch onto a different garment weight and every quantity rescales. Eight starter recipes are built in for a first batch before you have logged one of your own.
Meltline is free on the App Store. No IAP, no paywall, fully offline.
