THERMOMETER - G.H. ZEAL LONDON
Rectangular galvanised metal shaft with a semi circular ridged wide base and a semi circular ridged ring at the top. At the top is a metal ring handle. Running down the length on the inside of the shaft is a glass tube with red liquid in it. Stamped onto the metal are temperature increments down the left side and a makers mark on the right.
This steriliser was used by Olga Beales to sterilise preserving jars at their family home on the orchard at Roleystone (c1925-1956) and the orchard at Seville Grove. (c1956-1970s). Water was placed into the steriliser, bottles were then placed onto the perforated base. The lid was then placed onto it and then placed onto a stove top which would boil the water, creating steam that would sterilise the bottles. The thermometer was placed into the side metal pocket to monitor the internal steam temperature.

Preserving and pickling excess food, such as fruit from the orchard, was an important skill for any household if they wished to preserve food for long time storage in a time when cheap accessible refrigeration was limited as was easy access to shops selling fresh food.
