The Use Of Mercury

[belfastboy]

Great read Bob.
Thanks, never knew the date.
Put a solid pinpoint in when felt “changed” from that old felt feel to whatever.
I guess Stetson’s Vita-Felt process, 42’-47’, was the first?? victory we covet so. Except Vita-Felts were all over the place, at least in the ones i have. Go figure!

Ps: but…we could still break a thermometer and roll the mercury balls around with our fingers and coat a penny.
Those were the days of hats and fun!!

Yep, old enough to have parents that gave me old thermometres to break open and play with the mercury......"Crazy bout the Mercury"
