Jar measuring, a wooden wick guide, and clearer guidance from pour to first burn: • New help for an ordinary jar — find its volume with water and a kitchen scale, then measure the inner diameter in centimeters or inches • The calculator now checks whether the diameter you entered fits the jar volume • New wooden wick guide — what to measure, what to buy, why holders matter, and how to center, trim and test the wick • Open the wick guide straight from the calculator once the diameter is entered • Journal tips now explain how to tell a wick that is too small from one that is too large • The final screen now explains that the candle is poured and needs to set before you check the scent and the burn • Refined guidance on wax types, temperatures, cooling and the first burn • Materials Reference is now always available from Settings • Journal: clearer recommendation cards and a confirmation before deleting an entry • The haptic signal is back when the mixing timer ends • New feedback form in Settings Found a problem?

Wick sizing by diameter, honest check-in dates, and refined wax guidance: • New wick guide in Materials Reference — cotton wick sizing by candle diameter • The calculator and journal now accept an optional jar diameter, used for wick sizing • Journal entries now show a separate wick-check date and scent-evaluation date — previously a single date, even though the wick can be checked much sooner • The calculator's fragrance percentage now shows both as a share of wax weight and of the whole candle — easier to compare against a supplier's label • Updated soy wax fragrance-add temperature based on current data • Expanded cooling and first-burn guidance • New Materials & Equipment section in the reference guide: dyes, essential oils, plaster vessels, starter tool list Found a problem?
