Perlite/silicate composites - No good info? Forgot to mention that they are cast in pewter.
Here's the latest resuly. Pretty good except for ... |

Using a(n Ag) mirror RBF to carry out reaction with fused alcali Only one way to find out I guess. |

Using a(n Ag) mirror RBF to carry out reaction with fused alcali I wouldn't put much faith in the mechanical strength of the silver coating. It is extremely thin, an ... |

Perlite/silicate composites - No good info? @Rainwater: The disk was made with straight sodium silicate (3:1).
I'm aiming for 400-450°C, whil ... |

Using a(n Ag) mirror RBF to carry out reaction with fused alcali That's a very good idea. I think nickel is the best choice, at least among the non-noble metals. |
