I am teaching an online class beginning January 15, 2018. The class is about how to use Ian Currie's grid method to discover glazes at any firing temperature. The class cost is $89.
You can learn more about my online course and what a Currie grid is about by visiting my Currie Grids with John Post Facebook group.
I love the way that the long bat wings complement the rectangular nature of this extruded clay box. It was made by Jack Haroney when he attended art club.

My students are making Emoji art. It's weird, the Ancient Egyptians communicated using pictographs - pictures of what they were writing about. 5000 years later, we have gone back to communicating with pictures. We use emoji's to convey our feelings when writing on Facebook and texting friends.

The original Smiley Face, the grandfather of all Emoji's was designed by Harvey Ball in 1963.

I recently tested many Duncan commercial glazes at cone 06 and then at cone 1 over my majolica base glaze. The black and white dots on this tile are made with a product Duncan product called French Dimensions. It is designed for cone 06-04 but I like it at cone 1 over their Larkspar blue.

I added a couple of videos to this page where I demonstrate how to make a variety of inexpensive tools you can use with clay in your classroom or studio.

My friend Stephanie calls the surface on our clay bowls "active" meaning that the colored glaze on top interacts with the white base glaze below creating a variegated look. I think it looks awesome.



This year's crop of clay mummies awaiting the written artifacts that are sealed inside of them. Sixth grade students love this project.

Kids in art club made clay dogs and puppies. Mariah's is really cute. It is made of red terra cotta clay. It was then dipped in white glaze. Then the brown and black glazes were added over the top. It was fired to cone 1 which in our kiln is 2100 degrees F. You can see a couple of more dogs here.


A two pound bowl from a recent firing. It is glazed with a variation of my Glossy Base 17. This piece is slow cooled.


Frog Princes with Majolica glazes. Check them out here.
In this video I talk about how to choose a great clay for your art room, how to make a Majolica glaze and how to create shiny stuff - a sparkly coating for painted clay sculptures.

Kids in 5th grade are making clay bowls. We are using Terra Cotta clay - it's dark red. When they are fired the kids will dip their bowls in a white Majolica glaze and then paint bright colors over the top.


How to roll a slab!!!

Standing up so your body weight is helping to flatten the clay. ...and with a big smile on your face and a twinkle in your eye.



This week we are glazing our clay frogs. The frogs get the bottom waxed, then they are dipped into a white glaze. When this dries the kids paint colored glazes over the top. Then they are fired in the kiln and the glazes turn into glass. Nathan's frog is so cute!


This is google map of the visitors to my website over the last 24 hours. It's crazy how the internet makes it possible to communicate with people so far away and share what I do in clay.

Frog Paintings

Mother Nature is not good at straight lines - she prefers shapes that are wiggly, curvy and rounded. Artists call those organic shapes. Kids in Mr. Post's art classes are painting frogs that have organic shapes on them. Organic shapes allow frogs to blend in with their environment to hide from predators. Their bodies are their camouflage.



Clay Giraffes

Kids in art club created clay giraffes. We used the clay extruder to make the legs and the neck. You can see Mariana pulling down on the lever to extrude three long coils of clay. We used garlic presses to make the manes. I am really looking forward to glazing these with the kiddos.


I showed my first graders how to "sneak up" on the edge of a shape that they are painting. To do this, they start painting a little bit away from the line and sneak up on it. This helps them to paint inside of the shapes. You can just see the concentration on Chelsea's face in the photo.
Next week kids will be adding organic shapes to their frog paintings. Organic shapes are those found in nature - they can be curvy and wiggly.

Kids in 2nd through 5th grade could choose to draw their own frogs using basic shapes. They had a resource page full of frog drawings as inspiration. They had to make sure their frog filled the space, was in an environment and most of all looked like a frog.


Art of Ed Online Conference
January 31, 2015

I am presenting two videos about clay tools for the art room at this online video conference for art teachers.


Codi's Amazing Illusion

By closely following the principle of highlights and shadows, Codi's robot is already popping off the page and looking incredibly 3-dimensional. ...and it's so darn cute!


Kids at Work

I am teaching kids how artists use reflections and shadows to make their robot paintings look realistic. If they follow the steps their robots will turn out awesome.


Eat Mor Chickin

I love it when kids have their own ideas and bring them to their art. These are the creative kids who are so much fun to be around. There are more clay cows on this page.

Realistic Robots

Kids in grades 3-6 are learning how to turn geometric shapes into realistic robots. First they draw separate body parts. then they paint the robot grey and add reflections and shadows. The last step is to add colored buttons, facial parts and nuts and bolts.


If monsters went to school, these would be their school portraits.

Kids used tempera paint to create these cute little monsters that are smiling (or frowning) for the camera :)

Clay Cows with Organic Shapes

This week in art kids have been glazing the clay cows they made with organic shapes. Organic means that it comes from nature. If you shop with your kid, ask them to find the word organic as many times as they can at the grocery store. Cows have shapes that are organic. They aren't covered in circles or squares - their shapes are loose and wiggly - just as Mother Nature intended.

Line blends at Cone 1

I use line blends to invent new glazes. On the left side of the line blend at the top is a cone 6 glossy glaze. On the right side is a dry clay slip. By mixing them in 10% increments I was hoping to find a cone 1 satin glaze in the middle. It turns out that the blend that was a 50/50 mix of each glaze was the best one in terms of the touch test. That glaze is indicated by the yellow arrows. It felt great when I touched it. If you click on the top image you can view a much larger version of it.

You can download the glaze recipes by clicking on the blue links above.

I redesigned my website. This home page will be where I post updates of what is happening in my art studio and my elementary art classroom.
