James A Jobling (JAJ) took over the Wear Flint Glass Works in Sunderland, UK in 1885. Pyrex was first developed there in 1913 when one of their physicists, Jesse T. Littleton, was asked by his wife Bessie to bring home a replacement for her broken earthenware casserole dish. He brought her a piece of industrial borosilicate glass, nearly unbreakable, and when she tried it for a sponge cake it gave a uniform cake that was easy to remove from the dish.
Pyrex was launched as a commercial product in 1915, and quickly found favour with cooks all over the world. The company continued to create Pyrex for another 50 years, until 1973, when Jobling's license expired and Corning took control of the company.
This pattern, Tempo, was one of the very last created under the JAJ Pyrex company name. Please note there is some slight wear and tear on this pendant.
As with all Goosehouse Designs jewellery, these unique pieces are individually handcrafted by me in my studio.
The silver in this pendant is sterling silver, and is stamped with the .925 stamp.
This oval pendant measures 24mm x 20mm x 5mm.
The pendant comes with your choice of necklace -
wire collar 46cm/18"
box chain 56cms/22"
link chain 66cms/26"
snake chain 70cms/27"

The vintage china I use in my jewellery pieces is all recycled from pieces found at garage sales and op. shops, or through vintage dealers, who are happy to pass on some of their less-than-perfect items. I carefully cut out the selected section of china, shape it by hand, then grind the edges nice and smooth. I securely fix the piece into the sterling silver blank, then grout it so it stays firmly in place.
As with all artisan jewellery, some care needs to be taken to keep your piece in as-new condition.
The vintage china in your piece may well be up to a hundred years old, and needs to be treated accordingly. It is not recommended that you swim or shower whilst wearing your jewellery, nor that you wear it gardening or playing sport or any other activity where the item may get badly knocked. China is breakable, after all.
The sterling silver ring is easily adjustable, but care must be taken not to bend the ring band too quickly or too sharply. As with all metals, if they are worked roughly they may break.
The sterling silver bezel will enjoy a regular simple polish with a quality silvercloth. If you do use silver polish, do not get it on the china or the grout. Do not use strong chemicals on your jewellery.
