Why Didn't Someone Tell Me About Paperclay!?!

05 February 2017 - 02:58 AM

I picked up a bag of paperclay last week and I'm in love.

Let me back up. I have been creating for over half a century. I started painting with tempura, went to oils, then watercolor, then discovered acrylics, where I spent a few decades. I've turned my energy towards ceramics the past few years and have gone from clay to clay trying to find the right one for me. While I will still play with different throwing clays, I have found my sculpture clay.

The difference between clays has never been so defined! It's like comparing oils to acrylics.

Oils take a long time to dry and are far more particular that fast-drying, easily-fixable acrylic paints. Sculpture clays are perfect for those who choose to work more methodically. I want instant gratification and have been achieving some forms I thought I would have to really fight with by using paperclay.

 

I'm wondering if there are any pitfalls I'm overlooking and would love any hard-earned knowledge from those who have used this fabulous material.


Can't Locate Pemco 626 Frit Or A Substitute

25 December 2016 - 03:15 PM

And the recipe is one of the featured blog posts from just a few days ago!

 

I thought the Lana Wilson's Purple Aqua low fire glaze looked simple enough with so few ingredients so I figured I would start with that as my first self-mixed glaze. I got a gift certificate from hubs for my local clay store and went online to see what it would cost for glaze making supplies but couldn't find Pemco Frit 626 or Ferro Frit 3289.

So I started looking elsewhere online and STILL have come up with a big nada.

 

Can someone help me figure out a decent substitute? I hope to use it on Steve's White clay and possibly a low fire terra cotta.

Or, better yet, I'd love something similar in a mid-range glaze. I love the lavender/turquoise combo.


Local Clay Test

09 November 2016 - 12:46 AM

I am a long-time clay buff, but am only beginning to truly explore the medium, especially the chemistry end. I was never good in Science or Math.

 

So - I have some local clay I'm trying to learn more about. I made a little cone of it and put it in a tray with 07, 05, and 04 cones and bisqued it. The 07 cone had fully melted but the 05 was still standing. The clay however, crumbled back to a slightly darker version of what I started with. Does this mean I need to fire it higher, or is it indicative of the raw clay needing something to improve it? I know it's all about exploring but it would be nice to know which direction to look. My guess is to make more cones and trays and keep turning up the heat, but I'd hate to waste my small stash just testing. With proper rainfall, my dig will be hundreds of feet underwater. :-)

Point me the right direction?


Found This App On Reddit And Thought It Might Be Useful

08 September 2016 - 11:38 PM

But don't take my word for it - I've yet to mix my first glaze. Just wondering if anyone has used this app or even heard of it. Just copy/pasting here:

 

https://play.google....ontroller&hl=en

 

Here is the overview of what the app can do:

  • Add all your ingredients and their price to an ingredient list. The price information will be used to calculate the cost of each of your glazes, both in general, and for each specific batch you make.

  • From your ingredients list, you can build your ceramic glaze recipes. Tell the app a few weight/volume measurements about your glaze, and it will calculate the specific gravity.

  • Share recipes with a single click.

  • with specific gravity calculated, you will be able to accurately make batches of your glazes by volume (mL, oz, or gallons), by dry weight (grams), or by limiting ingredient (just give the weight of any and all ingredients you think might be limiting ingredients, and it'll calculate how much glaze you can make).

  • once you make a batch, save a record of it's size and cost for future reference.

  • You can also calculate both line and triaxial blend tests with as many tiles as you want really easily. Add labels to each tile so that you can later use the tile search function to find all the details of that specific tile just by typing in its label.

  • If you like the way a glaze tile looks, you can generate the exact recipe for that tile with a single click, and add it to your glaze list. This means if you wanted to, you could blend any of your current recipes together in a glaze test, and when you find something you like, it's really easy to just combine everything into one simple recipe.

  • Sync all of your data easily so that you can access the information on your computer or save it as a backup. Your recipes and glaze tests aren't stuck on the app forever, basically.


Kiln Elements Sagging, Is This An Acceptable Fix?

05 September 2016 - 04:36 PM

I've moved twice since purchasing my used kiln and some of the bottom bricks got weakened and the element channel crumbled. Pins worked for a few firings but now they won't hold either. I placed a couple short kiln posts in such a fashion that they keep the element off the kiln floor and this has worked quite well. However, I'm wondering:

 

#1- Will doing this cause any issues I should be aware of?

#2- How difficult would it be to replace the crumbling bricks?

#3- Should I replace the elements as well?
