Candle Making

Generate harmonious color palettes from a base color. Complementary, analogous, triadic, tetradic, monochromatic. CSS variables, Tailwind config, WCAG contrast.

Calculate total ROI and net gain or loss, then use CAGR for endpoint-only investments or money-weighted IRR for explicit year-end contributions.

Professional color picker with HEX, RGB, and HSL conversion, WCAG contrast checking, and palette generation. Pick colors and copy CSS-ready values instantly.

Generate scan-testable URL, email, phone, WiFi, or escaped vCard QR codes with UTF-8 capacity checks, color warnings, raster logos, PNG, and SVG.

Preview sRGB colors with adjustable color-vision models. Compare palettes and text pairs, check original contrast, and copy the simulated colors as CSV.

Reconcile a source-owned soap alkali record with explicit oil masses, alkali-specific rates, units, optional documented adjustments, and audit evidence.

Scale a documented fragrance percentage against exact base mass and whole batches without selecting or certifying a safe, compatible, or compliant rate.

Calculate essential oil drops and carrier oil for safe dilution percentages. Plan topical blends, roller bottles, and aromatherapy applications.

Reduce two bounded whole-number ratio parts and allocate one explicitly entered total with auditable proportions, percentages, and boundaries.

Select candle wick size from container diameter, wax type, and fragrance load. Match wick series to diameter for clean burn and full melt pool.

Calculate wax blend melt point from component wax melting temperatures and ratios. Predict blend hardness for candles, balms, and cosmetic bases.

Convert an entered unit cost and markup-on-cost percentage into markup amount, selling price, and equivalent gross margin with visible steps.

Calculate the theoretical break-even point and minimum whole sellable units, plus target-profit volume, contribution margin, and signed margin of safety.

Estimate melt pool diameter from wick burn rate and burn time. Free wax melt pool calculator for wax and related calculations.
