Well thats a good question.. probably 1 to 3%.  I mix the cmc in a gallon jug with water and let it set a few days. Then add a quart or two to about 4 gallons of glaze when mixing.  In this amount it gives even the most powdery glaze a nice hard coat when dry.

I use cmc gum in all my glaze formulas and I dip and spray. When spraying I add water so it goes thru the sprayer easier.  I didnt know there was a problem with gum and spraying and dipping for that matter.  My philosophy is this... its all just one big experiment and thats how we learn.

In reduction the oxygen in the iron oxide is removed leaving the pure form of iron FE.  Ive done heavy reduction on pieces sprayed with straight iron oxide and come up with a silver gray finish.

@HenryBurlingame I own 8  of the 1/3 hp models and 1 of the 1/2hp models. I cannot tell the difference unless I have something really, really, really big on the wheel. I've centered 25 pounds on the 1/3hp models just fine. They can handle anything a Brent CXC can handle because they have a ton of torque despite the lower hp rating.
As for the controllers, there are 5 or 6 different adjustments that can be made in the Skutt controller, such as IR Comp, top speed, low speed and a couple others, so you can dial in the pedal exactly how you want it. If you like IR Comp then you can turn it up. It's there, they just turn it off at the factory. Brent only has top and bottom speed. The Skutt pedal also has a much longer travel, which gives you better control. Skutt parts will be cheaper, although you shouldn't need any parts for either brand for a long, long time. I don't know what changes they made with the new Red line, but they still offer the SSX drive, so it doesn't sound like they changed much.

i am/was in contact with him as of 5/3/2024. He just blocked my email after requesting a refund. i talked with him on messenger and now he is ignoring me there too. i made a post putting him on blast on facebook. i want a refund. And if I don't get it by May 30th I am filing a police report. I have been nice and understanding about his physical health for the last two years. We are being taken advantage of. I also heard he gets really nasty with people. 

Hi and welcome!
Not a silly question at all. The good news is, hot won’t affect materials, but humidity might make a few things like soda ash or dolomite clump. Anything that is prone to this can be dried out on a baking sheet at about 175 F in a kiln or oven if it’s a nuisance. 

That is a perfectly good used wheelhead.  You could clean it up a bit with some steel wool.

karo, hope the wheel is still available for you to buy.   looks are only important to a fashion model.

Oil might help your foot pedal and governor to work smoothly, but not advisable to have it on surfaces that come into contact with your clay. #0000 Steel wool should smooth out the wheelhead surface. Lubricate with a little water while rubbing out irregularities, rinse well.

what are you referring to when you say "handle"?

Good job! Firing a wood kiln is a very grand dance.     Porcelain is quite delicate and wont hold up to that heavy level  of flame impingement like a good grogged stoneware. It seems they were overfired by a few cones!  You might try to use stoneware pieces to act as a bagwall.     The rebar will sag. Even more so if the coals build up and block the inrush of cool air from underneath .    I see you didnt weld them to the tbar so you could just turn them over each firing and get several more out of them.  I pull mine and lay them on a concrete slab and beat them straight with a sledge hammer.
Keep up the good work and let us know about your next firing.

I use rubbermaid trash cans. I first pug my clay and then put a layer of clay then plastic then another layer of clay so forth and so on. Then several layers of plastic film on the top and then the lid. Occasionally I will pour a cup or two of water inside to prevent too rapid of evaporation as we have quite a dry environment here. The trash cans are put on mover dollies for ease of storage.

What Neil said. Do you have sinks or toilets or tubs or showers that havent been used in a while?

What have you cleaned with this? Your floors? Your walls? I'm thoroughly confused about this. Sounds to me like you have a sewer gas leak. 

We call that color ‘snot red 

Whatever you do do not powder coast it inside as it will all chip out into the clay.
Yes on the de-rust paint OUTSIDE ONLY. Yes on the sandblast.
If the barrel is aluminum it can be be welded at a shop if its steel its ever easier to weld
This pug mill looks like a beater so pay very little for it. It pre vacuum I assume which means you still need to wedge the air bubbles out so plan on that
They make nicer units and I have seen many a bluebird with the vacuum feature for sale used as well.
This unit is pretty far gone and will take some big work to get it cleaned up -hopefully it's free to start with

Just under 3% less inspired ! But to your excellent point, when estimating burner output elevation needs to be corrected for as well as the heat content of your natural gas supplied. Both can combine to be very significant in mid and high altitude burner deigns. While as a percentage O2 is still just under 21%  more space exists between air molecules so quite a different mixture and burner settings sort of  like quite a bit different O2 absorbed with every breath! Your body can adjust or acclimate much more so than your burners. Good catch! This is definitely an important part of understanding what you have and designing for what you will need.

This.  One thing Ive found with fuel burning kilns not reaching temp is not enough oxygen. It seems like youve found the correct amount of gas by adjusting pressure up and down. .. but at 5000ft plus above sea level we have way less oxygen per cubic ft than at sea level.
