I do not know when my grandmother bought this Glass decoration and I cannot ask her because she died more than twenty years ago. All I can do is hang it on my tree and admire it gleaming amongst the deep green boughs, along with all the others that were once hers, or were bought by my parents, or that I have acquired myself, which together form the collection I bring out each year – accepting that not knowing or no longer remembering their origin is part of their charm.

Although I have many that are more elaborate, I especially admire this golden one for its simplicity of form and I like to think its ridged profile derives from the nineteen thirties when my mother was a child, because my grandmother took the art of Christmas decoration very seriously. She would be standing beech leaves in water laced with glycerine in October, pressing them under the carpet in November and then in December arranging the preserved leaves in copper jugs with teazles sprayed gold and branches of larch, as one of many contrivances that she pursued each year to celebrate the season in fastidious style.

Given the fragility of these glass ornaments, it is extraordinary that this particular decoration has survived, since every year there are a few casualties resulting in silvery shards among the needles under the tree. Recognising that a Christmas tree is a tremendous source of amusement for a cat – making great sport out of knocking the baubles to the ground and kicking them around like footballs – I hang the most cherished decorations upon the higher branches. Yet since it is in the natural course of things that some get broken every year and, as I should not wish to inhibit the curiosity of children wishing to handle them, I always buy a couple more each Christmas to preserve the equilibrium of my collection.

Everlasting baubles are available  – they do not smash, they bounce – but this shatterproof technological advance entirely lacks the poetry of these fragile beauties that can survive for generations as vessels of emotional memory and then be lost in a moment. In widespread recognition of this essential frailty of existence, there has been a welcome revival of glass ornaments in recent years.

They owe their origins to the glassblowers of the Thuringian Forest on the border of Germany and the Czech Republic where, in Lauscha, glass beads, drinking glasses, flasks, bowls and even glass eyes were manufactured since the twelfth century. The town is favoured to lie in a wooded river valley, providing both the sand and timber required for making glass and in 1847 Hans Greiner – a descendant of his namesake Hans Greiner who set up the glassworks in 1597 with Christoph Muller – began producing ornaments by blowing glass into wooden moulds. The inside of these ornaments was at first coloured to appear silvery with mercury or lead and then later by using a compound of silver nitrate and sugar water. In 1863, when a gas supply became available to the town, glass could be blown thinner without bursting and by the eighteen seventies the factory at Lauscha was exporting tree ornaments throughout Europe and America, signing a deal with F.W.Woolworth in the eighteen eighties, after he discovered them on a trip to Germany.

Bauble is a byword for the inconsequential, so I do not quite know why these small glass decorations inspire so much passion in me, keeping their romance even as other illusions have dissolved. Maybe it is because I collect images that resonate personally? As well as Father Christmas and Snowmen, I have the Sun, Moon and Stars, Clocks and even a Demon to create a shining poem about time, mortality and joy upon my Christmas tree. I cannot resist the allure of these exquisite glass sculptures in old-fashioned designs glinting at dusk amongst the dark needles of fir, because they still retain the power to evoke the rich unassailable magic of Christmas for me.

This pierrot dates from the nineteen eighties

Three of my grandmother’s decorations. The basket on the left has a piece of florists’ wire that she placed there in the nineteen fifties

This snowman is one of the oldest of my grandmother’s collection

Bought in the nineteen eighties, but from a much older mould

Baubles enhanced with painted stripes and glitter

The moon, sun and stars were acquired from a shop in Greenwich Avenue on my first visit to New York in 1990, amazingly they survived the flight home intact

These two from my grandmother’s collection make a fine contrast of colour

Even Christmas has its dark side, this demon usually hangs at the back of the tree

It is always going to be nine o’clock on Christmas Eve

Three new decorations purchased at Columbia Rd

A stash of glittering beauties, stored like rare eggs in cardboard trays

Russian cosmonauts from the sixties that I bought in Spitalfields Market

My first bicycle, that I found under the tree one Christmas and still keep in my attic
