Return to Galaxies

I’ve been beavering away on my galaxy marbles again. I stopped making them for a while as I wasn’t very happy how they were coming out, so went back to the drawing board and tried a couple of different techniques to form them. I am much happier with them now, and leading on from the complex cane techniques I’ve learnt a lot recently about ways of building up more complexity in the marble.

Wot more!?! Yes, I am still excited to find out how much I can pack into something just over an inch in diameter. I do like the idea, especially with these, that I can put a whole world – or even worlds! – into such a small space so the viewer has more things to discover.

If you go to one of the forgotten distant wings of The British Museum there is, (at least there was the last time I went there) a small display of items from the 1500-1600’s. Among them are what look like large boxwood pocket watches but inside they have the most amazing carved religious scenes. In a space less that an inch ½ across are dozens – yes dozens!- of figures clustering around a crucifixion scene, some of the spears soldiers are holding are no more than a splinter. How some medieval genus managed to carve these, probably with quite basic tools, inspires wonder and awe at their craftsmanship. I guess it’s seeing things like this that convinces me that even a marble or a bead can be a big enough canvas for any epic scene. One of the technical problems I’ve had with these marbles is down to the lack of heat I can get into the marble until I can afford a bigger torch. Looking at these is a reminder that I don’t need to make them huge to be full of interest.

On an exciting glass front I am awaiting a new shipment of glass colours from a factory sale in the USA. It’s rather battered my ‘big torch fund’ but it will mean some new colours and some glass I’ll have a decent usable quantity of. One or two I’ve been rationing because I’m down to a few stubs, so it will be great to go wild with some really exciting colours, including one of the sexist multi-coloured blues ever, and even two new reds!

In the meantime here are some pictures of one I’ve turned into a wine stopper – they are all the same marble but I am finding they really look different as I move them around which is exactly what I want, but makes a real headache of photographing them to show what they are like! This one is up at my folksy shop.

Edited as I've since found they are called 'prayer-nuts' and you can see a few on the British museum website, although they are more impressive in real life! http://www.britishmuseum.org/research/search_the_collection_database/search_results.aspx?orig=%2Fresearch%2Fsearch_the_collection_database.aspx&searchText=prayer-nut%2C&fromDate=&fromadbc=ad&toDate=&toadbc=ad&x=15&y=9

Opals !!!!

(New 30mm marble with opal, now on Etsy!)




Unlike ‘soft’ glass, working with borosilicate has some limitations of colours, ways of working, and what can be put inside. For a start buying it can be fraught with difficulties, I only know a few people using it in this county, and getting supplies is tricky. In the USA there are lots more people using it, which means more trade and it’s easier to get the more difficult items. Last week I had to launch a desperate plea on the Frit Happens website for one special effects rod rather than trying to put together an expensive import from the USA!

The USA have been using boro much longer than here, one of the amazing things discovered by some USA lampworkers that although many items can’t be used easily in borosilicate (gold and silver evaporate before the glass thinks of melting!) that one strange opal has the right properties for being encased in borosilicate (pyrex)

In France in 1974 Pierre Gilson was able to create the first synthetic opals. These weren’t bad imitations made with plastic and glass; they are physically and chemically opals, made by copying the extreme pressures and temperatures over very long periods (some can take 12-18months to form) that naturally make opals. It’s only under a microscope that they can be seen as different as they have no flaws like normal opals, so makes them stronger!

The best bit (for me!) is unlike natural formed opals they have no water content! Coupled with having same expansion rate as borosilicate it means they can be encased without cracking or exploding!

I bought a few some months ago, but as they still aren’t cheap it’s taken me a while to get the nerve up to try them out. I posted a picture on last weeks blog showing one; they make such amazing ethereal planets. I managed to get some tiny dot bubbled orbiting one which was a wonderful effect. I started on a second one I was just about to tidy the marble up and get rid of some of the extra bubbles & knocks when the gas ran out! Argh! I’m still debating whether to break it up for the opal, or sell it as a second as I can’t re-melt this one because the red glass in it might go a nasty colour if I do.
(My first Marble with a Gilson Opal!)

I have now made a very large 30mm marble (about 1 1/8 inch) with a lovely galaxy swirl, originally I was going to put the opal in the centre but it wanted to orbit on the arm which I think looks better as it breaks up the symmetry. Underneath I’ve done some lava-lamp effects with whispy yellow, green-yellow and blue glass, and a simple cobalt blue backing. It’s now in my Etsy shop, a little more expensive than some of my previous marbles, but it is rather special! I’ve really enjoyed working with these little treasures, and hope to include a few more as I really like the ethereal feel they give to my little landscapes, or should that be galaxy-scapes?
