Kiln

As you say, it is quite small. My (our) Paragon SC2 seems small enough for me, but if yours is adequate for your needs who’s to worry about it. I can’t just pick up the SC2 and move it around too easily!

I tend to programme mine for night-time running as I watch the power consumption, although I do have a power supply that can run mine for several hours off grid if I really wanted to. Even so, the modern kilns are quite economical - they are well insulated. I think your programmer is much the same - probably used industry wide?

l use it mostly for heat treating, annealing, hardening and tempering (the kitchen oven also gets used for tempering) of larger items that will fit. I’ve not dared to try silver soldering. I do intend trying powder coating (at some time?) and case hargening.

Also on the list is burning out casting patterns, but it would need better ventilation if I do that!

I liked your review. Who is your leccy supplier? Octopus?

It looks very well made.

Can the kiln be purged with an inert or reducing gas?

JA

As per discussions on another thread it looks to have a fake CE mark. Making furnaces that fully comply with EVERY regulation in order to CE mark them is a nightmare. The powers that be didn't consider this sort of equipment when they wrote the regulations.

Looks a nice bit kit and extemely good value for money considering it has a multi step programmer. You won't find a British made unit anywhere near that price - but it will be correctly CE marked.

From your review:

Being 700W and small it will be reasonable on running costs as at most it will use 0.7kWh per hour of use and at roughly 12p/kWh that is roughly 8.5p / hour.

BG? Are you really sure of the unit cost of electricity? I just looked and didn’t see a rate below 17 1/2p/kWh🙂. Small point but important for readers of your review, to be confident of its validity.

That would, if true, be very worrying ... in view of the Certificate displayed on this site: **LINK**

I have a Paragon SC2 - Bought it for enamel dial making - Im still learning that.

It does however make an excellent heat treat oven.

I have not tried soldering in it (yet), but using Borax on parts for heat treating makes for hardly any scale.

Maybe straight Borax will work as a silver solder flux? I use it when I solder the dial feet onto the dial blanks before enamelling them.

I also have a Paragon SC2. Up to now have used it to bake high temperature paints and also to heat treat a couple of chilled castings. Also intend having a play with glass melting.

Tubal Cain book on heat treating recommends a bit of charcoal in the furnace to selectively take out the oxygen

Colin,

You may find a lot of glass info on the ‘frit happens’ site. Forums are fairly dead but the info is still there.

You’ve given me an idea - the exhaust from the oxycon will be devoid of oxygen.... Our kiln has a door in the door (for ‘garaging’ beads) so might give access for injecting inert gas...
