more on strawing
Dear Experts
After the parts to be strawed are down to bare metal, should they be polished using oil and bronze wool, or just bronze wool? |

Delete the use of bronze wool all together.......polish by buffing wheel or coucous cloth.

Chemical strawing
Selenic acid H2SeO4 ----------- 10 parts
Copper (II) sulfate CuSO4 ---- 10 parts Distilled water ------------------- 1000 parts After a good pickling of the metal part put the part in the solution described above. Part will start changing the color from the yellow to the dark blue depending on how long you keep the part in the solution. Just take the part at the desired color and wash it in the distilled water. Worm up and apply olive oil. There you go, I just revealed more than 300 years old recipe on the net. One of the trade secrets. |

The best results I have gotten have involved heating the polished part to be strawed.
