Your manual should explain what you need to do. Prefiring empty is usually recommended so that your elements can form a protective coating of aluminum oxide. After that kiln wash the bottom of your kiln and your shelf and start fusing. 🙂
Thanks. I’ll do just that. Fire first then apply the kiln wash. 😎 I never did find any recommendations about applying kiln wash to the inside of the kiln, but it just makes sense. Of course not the heating elements just the bottom.
