SS mesh melt: black & white specks
Posted: Sun Jun 09, 2013 9:48 am
Hi,
I have two questions wrt the mesh melt that I did last night. I used a SS mesh (304) with 1/2 holes.
1- black specks
I had read on this board that SS 304 flakes but that these flakes can be brushed off the surface. Some of the black flakes are embedded in either the top of bottom surface (see circles in the two pix). I guess I could dremel them out. But I am more concerned with the ones that are embedded within the glass (see squares in the 2nd pix): these are a lost cause and I will have to avoid them when I select the inserts for my plates.
I hammered the heck out of the SS mesh this morning to ensure that all loose flecks are gone. Anything else I should do to ensure that my next melt mesh comes out OK?
2- White specks
I did the melt on a ceramic fiberboard (I had a bad experience with my first mesh when the kiln wash became embedded in the glass...). There are several 1-3 mm diam. chunks of white material. It does not look like glass. These are also embedded and could be drilled out. Are these fiber material? Anything I can do to avoid this next time?
If you look closely (pix 2), the bottom is peppered with white small specks. I do not have access to sand blast equipment. Would a 10 h soak in pickling vinegar (7% acetic acid) remove them all or I need something stronger?
Cheers!
