Cherry Heaven TV has made some short on-line radio and tv programmes about making and working with kilns. This one is about shaping and assembling firebricks at Paragon

To play, pause, or stop the player, or adjust the volume, click the Cherry Heaven Player controls. Whilst it's playing, you can drag the time-line slider to any new position.

Cherry Heaven TV has encoded the programmes to a net-standard FLV format of 320px x 240px. Other parameters have been set to achieve a practical balance of audio and video quality set against a likely data-streaming rate.

However, they're all over 1MB so, if you're not on a fast internet connection, they might pause and continue occasionally if the data stream can't keep up with the demands of the player.

If you're using a notebook computer, the audio quality will probably be poor, and might not be loud enough. To remedy this, you need some external loudspeakers:

The Cherry Heaven USB Stereo Loudspeakers don't need batteries, installing, or setting up: they're powered by the computer's USB socket and driven by the stereo-out socket. To learn more, use the Cherry Heaven link above the menu bar near the top of the page.

External loudspeakers will improve your enjoyment of music cds, mp3 tracks, on-line movies, dvd movies, video camera movies, games, youtube, and net-phone applications.

Firebricks are moulded from high-temperature clay. The mould can include cut-outs, rebates, joints, and drop-in element grooves.

Firebricks can be cemented or fixed together, are inexpensive, durable, and stable, and, in the unlikely event of damage, can be repaired or replaced easily.

Firebricks are heavy, so heat and cool slowly and evenly, making firebrick kilns ideal for materials or processes that need a long firing sequence.

Any kiln shape can be built: square, rectangular, hexagonal, round, or oval. Generally, firebrick kilns are top openers, although there are a few front openers: the square and rectangular Xpress series, the square GL 24, and the square Janus 24. Making a front-opening round or oval kiln is more complicated.
