Ni-Cr alloys basically have low thermal conductivity. So, a longer Hold Time is recommended to avoid insufficient firing (unbaked). This procedure allows porcelain to maintain sufficient strength and will prevent cracks even when tensile stresses are put on the porcelain. Therefore, we recommend the following firing program. These firing instructions are strongly recommended, especially for dental implant cases where the metal volume is large.

(Note) Depending on the firing conditions, there may be cases where the original properties are not demonstrated. Please confirm the points below for use.
・Conditions of firing differ depending on types or shapes of furnaces. Adjust the temperature in the range of ±20℃.
・Appropriate condition of Opaque after firing is slightly glossy, and appropriate condition of Dentine after firing is a light gloss.
