Can you fuse glass without a kiln

If those are the only kind of bottles you are interested in, that's the end of the discussion. However, you could probably do it with "normal size" bottles, and it would be inexpensive to try it. You are apparently aware of the typical microwave kilns you can buy to melt small hunks of glass. You can make a microwave kiln yourself, and I think a kiln designed for this purpose, with the proper procedure, would probably enable you to flatten bottles up to about beer bottle size, and in a reasonable amount of time.

They aren't wine bottles, but are a pretty similar variation on the theme. For readers unfamiliar with microwave kilns, here's an example of a typical kiln sold for melting glass chunks, or even metals, in your household microwave oven:. You can make your own, and you can shape and size it to your requirements.

The materials are available on Amazon if you can't find them locally. The video in the linked Instructable shows some very tall microwave kilns made by the author. He accommodated them by turning the microwave on its side and standing them in the long direction.

If your only objective is to flatten bottles on their side, like the examples in your link, that would be simpler. Rather than making a tall kiln and standing the microwave on its side, you could make a rectangular kiln that was squat, so it would cover much of the bottom of the microwave in its normal orientation, and be tall enough to accommodate the diameter of the bottle laying down.

To fit the tallest longest possible bottle, you could even make the kiln a little bit bottle-shaped narrower at one end , and fit it diagonally inside the microwave. With a large microwave, you could accommodate a bottle up to about beer bottle size.

There was some discussion in the comments about whether a microwave kiln generates enough heat to melt something the size of a bottle. Given enough time, it would, but there's a way to speed up the process.

Preheat the bottle in a regular oven up to the maximum temperature of the oven. Then put it in the microwave kiln. Hot glass absorbs microwave energy; the hotter the glass, the more energy it absorbs. The video in the Instructables link shows the glass turntable of a microwave getting hot enough to glow because the microwave was operated with the glass hot.

Preheating the bottle helps in several ways -- the bottle is starting at a higher temperature, and then getting a temperature boost from the microwaves in addition to the heat generated by the kiln.

A kiln is necessary to raise the temperature of glass to to degrees, while a blow torch can raise the temperature of glass to approximately degrees. Ignite the flame on your propane blow torch. Glass and glass-making ceramics can be melted by the process of microwave melting rapidly and directly by the gyrotron beam with a heating rate of over 1, degrees C 2,F per second. Can you melt glass without a kiln?

There are two ways to safely melt glass without a kiln: lampworking and using a microwave kiln. Lampworking involves the use of a torch to melt glass to the point of being easily manipulated. A microwave kiln melts glass effectively for small fusing projects. You can use a pottery kiln to melt glass and change it into beautiful decorative pieces to use in jewelry and glassware. The glass that is melted in a pottery kiln can be recycled from bottles to broken glassware.

So watch your glass. Glass casting is a process where you place glass in a mold to create a specific glass sculpture or design.

The mold must be placed in a kiln to fuse the glass together and form your desired item. Even though the box will catch high heat inside, but it will not release any excitement for the oven to get overheated, so you are safe. There you know how to fuse glass without a kiln. Sure, you will need to have some essential tools, but they are easier to get than arranging a real kiln. Hopefully, our tips will help you with everything.
