Ceramic

“Ceramic” and “porcelain” can describe different body compositions and firing processes, but the marketing name alone is not enough to select a candle vessel. Review the actual material specification, fired dimensions, wall structure, glaze, weight, surface finish and lid fit.

For candle use, approve the production-style vessel and then complete filling and burn testing with the intended wax, fragrance and wick system.

Ceramic color and surface appearance can vary slightly because the body, glaze application, kiln position and firing conditions all affect the finished piece.

Use approved physical samples to define the acceptable shade, gloss or matte level, texture and decoration standard. Keep the same reference and inspection lighting for repeat orders.

Start with the planned usable wax fill, target burn format, wick layout, label area, lid, box and desired shelf presence. Review outside dimensions together with the internal diameter and actual usable volume.

A wider jar may require a different wick configuration from a tall narrow jar. Request the drawing and sample, then confirm fill weight, component fit and burn performance before production.

Before filling, inspect the received containers and separate any pieces with visible damage. Keep vessels dry, clean and free from loose dust, and confirm that the correct jar, lid and decoration have been supplied.

Filling temperature, any preheating method, wick placement, curing and burn-test procedures should be established by the candle manufacturer for the actual vessel, wax and fragrance system. Avoid unapproved cleaning or heating methods that could affect coatings, decals or glazes.
