Subject: nichrome wire mesh dome
To: Paul Olivier

I took a long time for the nichrome wire mesh to arrive from China.
And it took a long time for the shop to make the mold to make the dome.
The dome in operation with a pot (100 gasifier) looks like this:

After a burn, there is no smell.
The pot does not blacken.
The dome does not change color after a burn.
Here you see the dome after 5 burns:

It looks like it was never used.
Ordinary 304 stainless steel changes color after one burn.
Nichrome stays the same.
Nichrome is special.
Nichrome does not change shape and keeps its original form.

The wire diameter is 0.20 mm.
The wire openings are 0.64 mm.
The open area of the wire mesh is greater than 58%.
Tomorrow Truc Duong will do some more tests.

Thanks.
Paul Olivier
