These lead-free ceramic Underglaze pencils are perfect for adding graphic and design elements to your creations. They can also be used for permanent marking and are able to withstand stoneware temperatures. For best results, the manufacturer recommends firing them at 900°C - 1000°C. Keep in mind that some colors may fade at higher temperatures, so make sure to test them before use. Keep your pencils sharp with a high-quality metal sharpener or sharp knife.
