This is a PDF document which contains convenient plaster mixing ratios, for use in your classroom or studio.


This reference chart is a fast guide for mixing US Gypsum / K-60 Pottery Plaster for use in mold making and slip casting.  I made it to help me make the process a bit faster as I am always spending time calculating how much to mix, and inevitably I also cannot find the correct container with labels, so this has amounts in quarts, ounces, grams, pounds, as well as volume units in cubic inches.  If you notice something incorrect or think of something that should be added please get to me on instagram (link below) @redneckpaycheck .  Thanks!



Artist Spotlight – Patricia Sannit

LEFT: An image from Sannit’s monograph of one of her larger installation pieces, Citadel.

I had the pleasure of visiting Patricia in her Phoenix home in late 2018.  I have always been a fan of her work, ever since seeing the large solo installation in Phoenix in 2011 in Tempe, curated by Peter Held.

Referencing antiquity and bridging history with the contemporary practice of installation mesh seamlessly in Sannit’s work.  While this is idea is nothing new in the small and often uninventive world of contemporary ceramic art, I find Sannit’s approach to be so beautifully crafted that it transcends easily into the realm of fine art.  There are so many directions you can take the visual allegories present: large vs small / one vs many; rugged markmaking with simple forms; color vs monochrome; data vs meaning; simplicity and complexity.

It’s quite visually overwhelming but in the best possible way.

Poder in Action

As a politically active artist in Phoenix I would like to give a humble shoutout to Poder in Action, a local organization focused on grassroots community empowerment.  They have an awesome sticker campaign, which Phoenix could always use more of.  I’m putting a few links to informative brochures they’ve produced below.

II have had many persons, artists and non-artits, suggest that its important to not make political statements to keep one’s audience broad.  My response is that, by not making a statement, you are making a statement, and that statement is complicity and acceptance of blatant problems you see in the world.  Police violence is an example of such problems, and it unequally affects many of the most vulnerable.  I love what this group is doing and wish there were more of them.

You can support them by donating.  Here is their website:  https://www.poderinaction.org/

Here is a link to their instagram:  https://www.instagram.com/poderinaction/

Their instagram is great because it has a lot of informative posts about how to protect yourself and use your legal rights within the current corrupt systems.

Here is a link to one of their informational brochures in Spanish and English.
