Found on the Folly - Old SAB Beer Bottle - 1944

Sport has been watched at Jeppe High School for Boys over the years.  Proof of some of the beverages consumed have been preserved under the playing fields and Collard's Folly.

This old South African Breweries amber beer bottle was found under the rugby stands on White Field.  Circa 1944 (Talana).

This bottle would've had a vulcanite screw in stopper.

I found a SAB vulcanite stopper on a previous occasion and made art with it😊

Vulcanite (I know you're thinking "Star Trek"😁, but no.......)

Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.
