Calculate glaze batch weight from unity formula and raw material analysis. Scale recipes to any batch size for consistent studio pottery glazing.
Create kiln firing schedules with ramp rates, hold times, and cone temperatures. Plan bisque and glaze firings for electric and gas pottery kilns.
Calculate clay shrinkage percentage from wet, dry, and fired dimensions. Plan pottery sizes accurately for clay bodies from leather-hard through glaze firing.
For simple blends, melt point approximates the weight-averaged melting temperature of components. Accurate for similar wax types; less so for eutectic interactions.
Blend MP (°F) = Σ (component MP × weight fraction)Waxes have a melt range, not a single point. Reported melt points are typically the capillary melt point or drop melt point from manufacturer data.
Range ≈ blend MP ± 3–5°F depending on component spreadHigher melt point blends are harder at room temperature. Adding beeswax or stearic acid raises melt point; adding coconut oil or soft paraffin lowers it.
ΔMP ≈ Σ (fraction × ΔMP per component vs base wax)Updated: July 2026
70% soy (MP 120°F) + 30% paraffin (MP 150°F): blend MP ≈ 0.7×120 + 0.3×150 = 129°F. Harder than pure soy, better scent throw, adjust wick accordingly.
80% beeswax (MP 145°F) + 20% coconut oil (MP 76°F): blend ≈ 131°F. Soft enough for lip balm tubes at room temperature with good structure.
907 g paraffin (145°F) + 45 g stearic (MP 150°F, 5%): slight increase to ~145.3°F but noticeable hardness gain for pillar candle durability.
Container soy (~120°F MP) cannot support freestanding pillars. Blend with harder wax or additives to reach 140°F+ before molding pillars.
Some wax pairs interact non-linearly. Always pour test samples and measure penetration hardness (dropping point) for production formulations.
Blending waxes changes melt point, hardness, and burn characteristics. This calculator estimates the melt point of a wax blend from each component's melting temperature and weight ratio for candle and cosmetic formulation.
