The Chemistry Laboratory 1970

Very welcome photographs supplied by Eric Brown, Chemistry staff 1965-71.
He writes:
Here are some open day shots (don't know what year) and the Chemistry staff replete with very dirty lab coats! Also two shots from G&S productions with Girls' GS.

On the Chemistry Lab 1970 page, that's me, earnestly demonstrating pH to three eminent chem teachers! I'm assuming it was during my first year at the school - I only did chem for two years - so it was either 1970 or 1971.
Mr Brown was my teacher in the first year (Mr Andrews in the second).
I also recognise (DJ) Cole from my class in one of the other photos - bottom picture, boy on the left without a tie!

Hope this useful.
