Dnalot,
I hope the healing of your hand is moving quickly.
I have a few questions: The burns on your hands, in the pics, indicate the damage to the hand, now you say that the pieces of glove that was placed into the oven work as expected, except the gauntlet. So the question must be asked is the damage, to your hand, on the hand or on the wrist?
You say the cut pieces worked as expected with the exception of the gauntlet portion,correct? What were you working on? Most of the welders and other hot workers I know wear long, buttoned down sleeves. The sleeves would of course add a layer of protection,were you?
Are you a professional at working with hot items?
While I have no dog in the fight, I must say I find a few grey areas in your story.
If your point is do not buy HF gloves,so be it, buy gloves like Tillman or such.
I am ready for this story to pass into the vast wasteland of the net.
