What is Karma (17 Oct 2019)

Karma is one way to say "thank you" to a poster that was of particular good help to you on your posted question or problem. It's OPTIONAL and avoids cluttering up forum posts with many "Thank you's". You can also personally Thank the poster and show that they have helped you by clicking on "Thank you". The higher your karma value and the number of "Thank you's" is a fun measure of your value and status about TecHKnow. You can increase (or decrease) a persons' Karam by clicking on the "more" icon just below their user Picture/Avatar

Today I have been presented with a hammer with slag and broken glass welded to the head. Result of a standard iron/sulphur experiment beaten to death with aforementioned hammer whilst a molten mass ... :ch

Haven't found where it says "Whilst still red hot ..." in the risk assessment or method ... or indeed, where it reads "For best results ignore this risk assessment and make it up as you go along" :sp

Grinder (metal variety!) on standby for end of school day ...

Happened here too.
Also a plastic coated magnet ( cdn.images.fecom-media.com/A46929.jpg easy to separate from the inside magnets) to test the iron when it's *cooled* down :-(

At least the hammer looks a lot cleaner than when it was given out!
