Opaque Firings:

Spatulate the Pulse paste opaque before applying. Use the Pulse paste opaque liquid for dilution, if necessary.

Apply a full even layer of paste opaque to the framework and modify with intensive opaques according to the desired chroma intensity.

In the case of non-precious alloys, it is recommended to use powder opaque for the first opaque firing/ wash for the best results.
