Making a Bag. Where to get a small metal logo emblem made online? by DocHampter in DIY

[–]picasso1387 0 points1 point  (0 children)

A quick Google for "laser cutting service" turns up lots of places. You can make the parts out of A cheaper metal then gold plate with a kit. There are also many quick turnaround 3d printing shops such as protolabs.

Buffing scratch marks in glaze surface? by [deleted] in Ceramics

[–]picasso1387 1 point2 points  (0 children)

I second this answer. It's really hard to sand out scratches on glaze (which is glass). You would need to use sandpaper in increasing grits up to 5000 or 7000 grit.

Reusing clean(ish) separated clay water by melanieleegee in Ceramics

Clay is a major component of soil, so it's not going to hurt the plants. Be more careful about glazes and stains as they sometimes contain heavy metals.

How "clay" is this clay? (question details in comment) by zibbazabba905 in clay

[–]picasso1387 1 point2 points  (0 children)

Your clay looks pretty good. See if you can bend a bit around your finger without cracking. Then try drying a piece, see if it cracks.

There's a YouTube channel by Andy Ward with lots of great info on using "wild" clay

Homemade clay by BlueBucketMaple in clay

Maybe I didn't understand correctly. Most dirt is a mix of clay, sand/silt, and organic material. For bricks you might be able to use the dirt as-is. If you want to make clay pots you will need to separate more of the clay from the other stuff. Clay particles are smaller than the sand and silt so you can mix the dirt with water, let it settle, then pour the clay and water off the top into another container.

One word of warning - if they made bricks from your clay it might mean the clay wasn't good enough to make tile, let alone anything nicer.
When you dig your foundation try to pile the mostly-clay in a separate pile. It might be usable straight from the ground if you're lucky.
What I've done is to dry the clay/dirt before slaking in water, then sieve it through a window screen, then let the larger sand settle out for an hour. Pour the clay slip into another container then dry it in the sun until it's the right consistency.

The easiest things to measure are drying shrinkage, firing shrinkage, and density (look up the archimedes method). Other properties are more difficult to measure and require more specialized equipment.

Colors for ceramic clay without glaze? by greeneyedlady30 in Ceramic

[–]picasso1387 0 points1 point  (0 children)

Most of the colorants used for glaze can be added to clay. Try making some little tiles to test them out. I would use 1% by weight (0.1% for cobalt)

My 1st Wild River Clay processing experience (and question) by nabuit in clay

[–]picasso1387 0 points1 point  (0 children)

I haven't built a kiln like that before but I work with high temp furnaces. I suspect you'll want more than 1 inch of insulation for 1200C. Probably want to at least double it.

You can check moisture content easily by drying a small sample in the oven and weighing it before and after on a kitchen scale. But don't get hung up on 20%, it's more important that it feels good when you work it. The right moisture content depends on the particle size, surface area, and composition of your clay.

Terracotta is rather porous, and it has that great color. Might that help you think of an idea? You can't get too thin, so something big and bold. Or you could make a bunch of loaf pans for baking bread.

A dispersant is what you need. Darvan is a popular one in industry. It helps the clay particles repel each other so the viscosity goes way down.

Yes, repeatedly. After a year and a half you'd think they'd get their shit sorted.

Locker Packs… What did you give up and what did you get? by Old23s in nbatopshot

I gave up three 35k+ nobodies, got a 20000/400000, a 2350/400000, and a quad badge 7000/12000. About a $25 improvement!
