"KILN CARVING" with glass!
The title may be a little confusing to some of you.........I can hear you thinking "how does she carve GLASS? Surely that is not possible?"
Well, you are right. glass is not wood, or stone. If I decided to go at a piece of glass with a hammer and chisel, I would end up with a pile of glass pieces and dangerous shards. But there is a way to "carve" into the glass....by using the kiln to do it!
There are different ways to "kiln carve" .“Kilncarving” is a term coined at Bullseye (manufacturers of art glass for glass fusing) to describe a kilnforming process that achieves a bas relief, textured, or sculpted look in glass. The process involves cutting a pattern or design in ceramic fiber paper, then stacking glass on top of the pattern and firing the piece in a kiln. During firing, the underside of the glass slowly softens and conforms to the ceramic fiber paper pattern, assuming its contours and textures. Here you see a "tree of life" pattern, the deep texture is at the back of the piece.
Alternatively, the same effects can be achieved by using a ceramic "texture tile", produced specially for this purpose. The tile needs to be treated with a "glass release" product, so that the piece lifts off easily after firing, and can then be formed into a bowl, or vase, if required, during a second firing.
The piece can be decorated...I added real gold detail to the tree of life, by fusing the decoration onto the piece before the slumping stage to give it a gentle curve:
I personally enjoy the look of textured glass, I believe the kiln-carving makes it look rather special. Unfortunately, I have badly shaky hands, so carving fibre paper is not on, I might end up minus a few tips of fingers!...........so I generally use texture tiles and I am grateful they exist! Here are some of the pieces I have made to date. I plan to try a vase next, with the lovely deep texture on the outside...watch this space!
I used rainbow iridised glass for this piece, the iridescent side sparkles in the light. |
Here is the other, smoother side:
Working with either your own designs cut from fibre, or a texture tile, bought or created yourself, will give you beautiful glass with an unusual look, and anyone who does not work with glass and kilns, will have no idea how you achieved this!

COLOURFUL GLASS ACCESSORIES
Some of you may know that I make glass accessories, employing a technique related to the fancy-sounding "Pate de Verre" technique, using glass paste, made from finely ground glass and a binder of some kind, which is fully fused in a kiln. My pieces are formed in moulds, frozen until solid, de-moulded and then fused in the kiln for 12-14 hours.
I sell them for use as "accessories" for glass artists to add to their glass works. It is not always easy for me with my annoyingly shaky hands, but I do manage it, with time and patience. I thought I would simply share some of the photos with you and also, tell you something about Starfish/Sea Stars, which I sometimes make.
Sea stars live underwater, but that is where their resemblance to fish ends. They do not have gills, scales, or fins. Sea stars live only in saltwater. Sea water, instead of blood, is actually used to pump nutrients through their bodies via a 'water vascular system.'
and some recent flocks of birds! great for adding to seascapes, or landscapes:

UNPREDICTABLE BUT NICE SURPRISES IN GLASS

SIMPLE SCREENPRINTING FOR GLASS ARTISTS

NO NEED TO CUT THE GLASS!
Glass comes in crushed form....powder, or "frit" which is glass crushed into various sized pieces - fine (like sand), medium (coarse sand) and large (like small stones) frit can be purchased, or created.
Then, items of glass can be made using either powder or frit, which means there is no need to haul large sheets of glass out of units and onto tables, to be cut. Sheet glass is very heavy, and if, like me, you have problems with mobility, balance and strength, it can be exhausting to lug around. Also, I have problems with "shaky hands" (getting older is not for the faint-hearted) and my ability to cut, draw or paint is now severely limited.
BUT I can sit at a table, fill a mould with either powder or frit, and "cast" my glass pieces, which is the term used for certain methods. Then, the piece goes into the kiln, my silent partner.
In the past artists have used this technique to create wonderful pieces, via a process called Pate de Verre -but it is long and complicated. It is still used today by some marvellous glass artists . Here you see students in a class being taught how to line a plaster cast with powder:
This picture shows students creating and then filling their own plaster moulds. Making a plaster mould is a very messy, tricky, time-consuming process. Filling is not much better! sometimes a process called "lost wax" is involved, which means creating a model from wax, pouring plaster over and around the model, and then melting the wax away so that glass can then replace the wax.............need I say more. Only for the very patient. That is not me.
Here is a finished, modern piece:
Often, the plaster is "broken" away from the glass and cannot be re-used.
But for those with limited energy and stamina, there are more simple approaches to casting glass pieces. These simpler methods are personally giving me a new lease of life! I have previously shown some of the pieces I have produced, and here are more to show you. I really want to say that I am writing this mostly to encourage artists who find themselves struggling with problems following surgeries, like me ....it might encourage you to know that there may be less taxing approaches worth trying.
The bowl at the top of this page is a good case in point. Hard to believe this is just made from the crushed glass below it, isn't it! Red Frit and black powder were placed into a ceramic mould, and fired to a specific temperature which allows the glass to melt, reharden and soften into this beautiful form. That mould can be reused many times.

Is it a tree trunk or is it a ladder?
I often find myself biting my tongue when looking at glass images of Silver Birch, or Aspen trees, created in glass. All too often, the artist has simply cut strips of white glass, and painted a few horizontal lines on them, and plopped them down onto a background. They look like white ladders, frankly, dodgy ones, and not the least bit like nicely observed, natural-looking tree trunks...they have no personality, no character, and look stiff and unrealistic. These two sketches show what I mean:
Often, light gives us a sense of "form" - the roundness of the trunk, as it illuminates one side, and casts a shadow on the other. But there are times when the light is subtle, and there is no obvious shadow. Then, we need to use the information provided by the bark. And the rules of perspective.
PERSPECTIVE FOR CYLINDRICAL FORMS.
At our eye level, horizontal marks on trees will be horizontal. As we look DOWN toward the roots, the marks will "dip", and as we look up towards the sky, the marks will appear to arc upwards. This is a rule of perspective. It will be very obvious when you are close to a tree; much less obvious from further away. You can prove this to yourself with a drinking glass or even better, a cardboard tube. Hold the top rim at eye level. It will be straight. Lift the glass/tube, and look UP at the rim. It curves upwards. Drop the glass/tube, and look DOWN at the rim. It will curve/dip downwards.
Have a look at the images below, they show what I mean:
