Hi everyone! Have been playing with my new kiln and LOVING it!!! Thinking
about pre-emptively buying stock in the electric company to recoup some of
my costs in running the thing day and night. But aside from the fact that
glass will be making me a pauper in short order, working with warm glass is
fascinating!

With that said, I wanted to find out if this is truly the forum for
discussion of warm glass (I have SOOOO many questions!) or should a new
newsgroup be initiated. 'Cuz time's a-wastin'!!! I need to SHARE and TALK
and DISCUSS this new love of my life!!!! Boy, I am such a girl!!! LOL

Look forward to hearing from you all (yep, even you sasspots!!!)

Cost of electricity is much less then most expect. If the label on
your kiln doesn't specify the wattage of your kiln, you can calculate
it by multiplying the amperage X the voltage. Then check your power
bill for the price per kilowatt hour you're being charged. Multiply
that price X the wattage X 4 hours (that's the average amount of time
your kiln is actually consuming power for a full fuse firing).

As to establishing a new group, why reinvent a wheel that already works
perfectly? If you want to discuss kilnforming (in all it's nuances) go
to http://www.warmglass.com

Glad you're enjying the kiln - there's an awful lot to learn - but the
best way I've found is to experiment, and keep notes !

There's lots of expertise over in the warmglass forum - but I
personally find it much easier to read this newsgroup, rather than
keep checking a web-based offering.

By all means ask away here -
what sort of kiln do you have and what are you making with it ?
Tried any dichroic glass yet - that's lovely stuff to play with !

As usual, Brady, in your rush to look important you offer more WRONG
information.

Definition: A kilowatt hour (KWH) is 1000 watts of current flowing for
one hour. (Kilo=1,000) Eh?

Once the wattage of the kiln (or any electrical device, for that matter) is
known, that wattage figure must be DIVIDED BY 1000, "then" multiplied
times the hours (or fractional hours) of use and "then" times the KWH price
rate to determine cost of operation. It's grade school math, you dummy.

I know you aren't too smart, so read slowly and look at these examples,
maybe you'll get a clue:

An 1800 watt hair dryer used for 15 minutes at $0.10/KWH is (1800/1000)x
(15/60)x $0.10/KWH =$0.045 cost or less than a nickel to dry your hair.

Running a 150w power supply on a PC left on for 24 hours would be:
(150/1000) x 24 x $0.10/KWH = $0.36 per day.

My electric bill came today. We used 1079 KWH in a 31 day billing cycle and
the bill was 75.90 plus taxes. That's about $0.07/KWH, so my examples above
are off a few pennies.

A 40A/220v kiln is 8800watts, or 8.8KWH if it runs for an entire hour. On a
hypothetical cycle of 4 hours, that is 35.2KWH or about $2.46 at my local
electric rates.

Once again, the Canadian prairie dog pops out of his hole, barks a bit, and
takes a round right between the eyes. When will you ever learn?

Not wishing to get all nerdy about it g but.....

Moon's calculation would be fine if the heating element in the kiln
was 'on' throughout the whole of the firing cycle.

This isn't the case - on my little SC2 kiln you can hear the relay
which switches the power to the element clicking in and out as the
controller attempts to provide the required temperature rate. The
elements will be 'on' for a shorter period of time as the kiln ramps
down - and may not even be on at all as the thing cools to room
temperature.

Even with a 'manually' controlled kiln, I think that you control it by
switching resistance in series with the elements - which reduces the
current and so the power consumption.

I guess the only 'simple' way to find out is to actually fire your
kiln with some means of measuring power consumed - or run it for a
cycle with all the other electrical 'things' switched off - and read
the utility meter at the start & end of the cycle.

In the grand scheme of things, it's one of those things that's
probably not worth the effort of calculating g - as a very rough
rule of thumb you could take Moon's figure and divide it by 1/2 or 3/4
- probably wouldn't be that far out....

Life's too short - back to the glass ! g

Hi again

big snip

OK Adrian - back in your hole ! (ducking those bullets g)

I see that Dennis has taken the intermittent nature of the power
consumption into account - sorry - should have read it all a bit more
closely....

FWIW - the webpages over here (UK) claim that the SC2 costs less than
50p to run a 'cycle' - that's just under a Dollar to those of you in
the USA.

At those sort of costs, and on a 'commercial' basis, the electricity
involved in running the kiln is a tiny amount of the costs involved in
producing saleable items - so probably not enought to worry about...

To swiftly paddle my canoe into less controversial waters (I Hope!) -
I'm toying with the idea of buyinf another kiln.
The Paragon SC2 is great for little pendant pieces - and for smallish
dishes / kiln-cast pieces - but I'd like to be able to make larger
pieces - say up to 12" diameter.

One UK retailer is offering the Skutt HotStart Pro or the Paragon
Fusion 7 - for about UK Pounds 720 - 750 each inc tax. (About $1300)

Any comments for or against these models - or suggestions for an
alternative...?

We're moving to Ireland in the near future, where the 'purchase tax'
is even higher - which is why I'm thinking about a new kiln 'now'...


Thanks in advance

Nice website. BTW, in your link above, you have a comma between "co" and
"uk". Had to change it to a "dot" to get the link to work.

Did you do the site design yourself?
