In-Depth Crafting Guide & Density Analysis
Wax melts and clamshell tarts are one of the most profitable products for home fragrance makers. Because they do not require wicks, flame safety testing is simplified. However, wax melts demand hard, shrink-resistant tart waxes (such as Golden Wax 492 or EcoSoya Tart Wax) so that cubes snap cleanly without leaving greasy residue inside the mold.
This soy wax melt calculator helps you batch calculate for multiple clamshell molds. It multiplies cavity counts by tart wax specific gravity, automatically accounts for a 5% pitcher-cling waste factor, and splits dry wax flakes and fragrance oils at 8%, 10%, or 12% saturation levels.
Frequently Asked Questions (Soy Wax Melt Calculator)
Why can wax melts hold higher fragrance loads (10%–12%) than container candles?
Wax melts have no wick to clog and produce no open flame. Because they are melted over electric or tealight wax warmers, they can safely absorb maximum fragrance oil saturation (10% to 12%) without soot, smoke, or flash-fire risks.
Why shouldn't you use container soy wax (Golden Wax 464) for wax melts?
Container waxes like GW 464 are formulated to adhere to glass and have a soft melt point (~115°F). In plastic clamshells, container wax will stick, smudge, and crumble when broken. Always use a dedicated pillar/tart wax (like Golden Wax 492, NatureWax C-6, or Blended Waxes BW-921) with a higher melt point (~130°F–140°F).
What is the correct pouring temperature for plastic clamshell molds?
Pour melted tart wax between 140°F and 150°F (60°C–65°C). Standard thermoformed PET plastic clamshells melt or warp at temperatures above 160°F (71°C).
How long do soy wax melts need to cure before melting?
Soy wax melts require 7 to 14 days of curing in a cool, dark room. Soy wax forms a complex crystal lattice over time; giving the fragrance oil two full weeks to bind within the crystalline structure delivers maximum hot throw when melted.
How much wax does a standard 6-cavity clamshell mold hold?
A standard 6-cavity clamshell holds approximately 70g to 75g (2.5 oz) of total melted wax and oil mixture. Each individual cube holds roughly 11.5g to 12.5g.
