Sirs ., I have just had a conversation with a metal worker ., and were talking about the use of green Swarfega as a temperature indicator when heating metal to annealing temperature .. As i remember ( I saw the process in the 80's in passing ) under heat to anneal., the metal ( aluminium or silver ) or the Swarfega would blacken .. Have you any record or knowledge of this process .? For further reference I did find a ref to Swarfega as a tapping compound in a Google Books ., "Ceramic burners for model steam boilers" ., by Alex Weiss ..You guys are more than something we wash our hands of .! Keep up the great work..

The tough range is incredible. I love it so much.

The new tough range looks really promising

This was really interesting. I'm a huge fan of Swarfega

I love Swarfrega

i want the 1990s bucket any one know where does it

Now THIS is about Swarfega.

This doesn't have ANYTHING to do with Swarfega. Very disappointed. Will only watch one or two more times.
