How do the bubbles in the glass

• How do the bubbles in the glass

I have often seen the reports of the glassworks, many of them in the internet, because in such places often lead tours. But never once have I seen in a reportage, how the glass objects are inserted various foreign bodies. moreover make bubbles. To find out, I went to Tavastia province that is located in Finland.

Why go to the given long to figure it out? - you ask. No, of course I went to Finland to learn and see not only the glass-blowing studio, but knew how to get inside glass bubbles I glassworks Mafka & Alakoski.

Manage and work here two masters - Masha and Kari. Kari is now gaining on the metal tube in a special oven glass, from which to make a glass mortar. The furnace temperature is kept constant at 1200g. Celsius, the glass was constantly runny.

Raw materials for the future of mortars, vases, glasses, candlesticks and other Souvenirs bought in Sweden. This granular blend.

And this is the whole set of tools for creating wonderful glass products, which will decorate the interior and pleasing to the eye.

But the tools it is currently suitable for the home of the Inquisition.

Special wooden spoon, which is shaped glass.

And what this tool will see a little later.

The second furnace, which is used from time to time to warm up the glass, so that it does not solidify earlier than necessary, otherwise it will be difficult to give it the desired shape.

At first Curry gives the glass shape.

Align and thin forceps base, while rolling up and down the tube, or molten glass will flow down.

Then, the resulting bead is clamped in a special form.

Curry blowing into a tube so that the mass has taken the desired shape within a mold, sorry for tavtalogiyu.

So the tool looks from the outside and inside.

tool and Grooved walls impart a glass ball surface.

Glass bowl again dipped into the red-hot furnace with molten glass, reeling him a little glass. Now use a spoon larger size.

Also used wet paper folded in several layers. the glass surface is slightly cooled, it becomes more compliant for the further processing.

Now you can see that the bubbles formed inside the glass. That rippled the surface of the previous sphere made it possible for their appearance. The secret was revealed that simple!

Again, warm up in the second furnace and processed further.

While Masha twists and forms of glass, Caria is blowing into a tube attached to the bottom of the next mortar shape.

Now you need to change the mounting position to handle the neck. For this Kari takes a second tube with a small amount of hot glass and attaches to the bottom, and Mary forceps and other instruments chips workpiece from the first tube.

Next, you need to cut off the neck too much.

And with a special tool to give the correct form of mortar. Now you need not to blow into a tube.

Mortar is almost ready.

Beauty!

One can only split off the phone and using the torch to remove the roughness.

Then the mortar, as well as other glass items should be placed in a special furnace at a temperature of about 500 degrees Celsius, in which it will gradually cool down. This is done to ensure that the product is not exhausted, and not cracked by rapid temperature drop.

And look ready mortar. 30-40 euros and it's yours!

They saw immediately another product with an interesting surface as if cracked. We were offered to guess how to achieve such an effect, "cracks". I'm guessing right, and you?

It is very simple.

You just need to submerge the glass and quickly get back. Well, then again in the oven to warm up and to treat wooden spoons and wet newspapers to smooth the cracks.

In the studio doing a lot of things, that's like Christmas balls.

Balls with even more bubbles, for interior decoration.

vases of various shapes and colors.

Even alien lamps. Cool looks.

And such treasures of Murano glass.

In the workshop Masha found a vintage cash register that it is currently working, and stands as a runabout.

Rarity and modern payment terminal, there is progress!

But that's not all. We then Mary showed master class lampwork - the creation of small articles of glass tubes.

Today we will do a bird, almost the same.

For this purpose the metal rod with a special surface is applied a layer of molten glass.

From the looks that Mary makes everything easy and simple, but this ability she studied 6 years in art school, and then again when he took this craft.

A pair of minutes and our bird - Snowy owl is ready! Look like?

owl figurine is placed in the same oven as the mortar, but smaller in size, to gradually cooled.

Here it makes a lot of interesting things, including glass photo. and if you want to see for yourself how to create such wonders, you can completely free of charge to visit the glass-blowing studio, and for a fee with their own hands to create the original thing. there is a fee to visit the individual groups.
