Partial black porcelain using wood charcoal as carbon source: characterization of porcelain body part

9.5.2026

Abstract

This paper observes the fabrication of partial black porcelain by carbon diffusion

from wood charcoal as a solid carbon source, and the characterization of body at bottom

area. The porcelain cup was created by conventional ceramic technique. For second

firing step, the cup was set on the wood charcoal pieces contained in a closed refractory

container and fired at 1250C for 1 h. The traces of carbon compounds at different

positions on a cross-section sample were detected by Raman spectroscopy and X-ray

photoelectron spectroscopy (XPS). Graphitic carbon and SiOC were discovered.

Furthermore, graphite peak was detected by X-ray diffraction (XRD). This work2

provides a confirmation of solid diffused carbon from wood charcoal into the porcelain

body by scientific techniques.

Keywords: porcelain, carbon, wood charcoal, firing technique

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
