Switch to Berol 949 Silver pencils. Made by the same company as your
Verithin's, but the lead is about 1/8" diameter. Welding supply and Art
stores are the sources around here. For stainless they make a large lead
dark red that works . Eyeliner pencils work well on stainless also.
I got started on the silver pencils while millwrighting in the local
sawmill's around
25 years ago. A little expensive, but well worth it. I'm not sure if I
own a piece
of soapstone any more. Where the pencils really shine is on wet/dirty/oily
They will mark where soapstone doesn't work. Also the mark doesn't blow
away ahead of the torch.
