Opportunity to Learn Natural Adobe Plaster Interior Sculptural Techniques

RMS_Sunroom-glass-table-arched-window_s4x3_lgAs passive solar design  becomes more widely understood, design will mean more than just bringing in the light and heat… and demand will grow for the most beautiful methods of bringing thermal mass into the interior of a home.

In this article:  – What is and why care about thermal mass?  (It’s all natural, inexpensive, local, artful – and makes  our homes more efficient.)
– A Silver City, NM, opportunity to learn sculptural techniques.

Thermal mass is what holds the heat inside a house, so it doesn’t escape through leaks or when you open the door.  It greatly moderates the natural “temperature swings” from day to night, and keeps a sun room from becoming unbearable, as it will, if it has no thermal mass.  Indeed, it is a common complaint about sunrooms – that they get too hot to enjoy and must be shaded.

This does not need to be the case!  The sunroom doesn’t need shade; it needs thermal mass and probably venting or other airflow assistance to help move the heat to the rest of the house.

I brought 1.5 tons of thermal mass into my home already and have plans to soon bring in at least a 1/2 ton more.

Thermal mass is anything heavy that absorbs and holds heat, such as adobe, stones, tiles, bricks, and containers of water – nothing high tech, nothing expensive, but simple, easy-to-obtain, even ancient materials!  These, when exposed to the sun, will absorb and hold the heat, and when the heat source is gone and the day cools, they release their heat slowly, all through the nightand that’s the key.

The most common interior materials in modern American homes are drywall, wood, fabric, foam padding, and insulation, which don’t hold much heat and whatever they do hold, they release readily, saving nothing for the cold nighttime.  Besides that, their components often degrade in heat and light, so it behooves us to protect them, in front of windows or in sunrooms, and this can best be done, not by shading that valuable wintertime sun, but by absorbing the heat to use – by bringing thermal mass into our homes.

Every home can benefit – even if you heat with a fireplace, gas or electric – by incorporating thermal mass, for the same reasons as above.

Natural plaster is inexpensive, natural, non-toxic, local, and very beautiful – and of course it can make your home an art piece of your very own creation!  You can show off or keep it simple and classic.

Some say the tons of clay continue always cleaning the air.  And most everyone agrees: “It vibes beautifully.”

My first outdoor carved natural plaster wall relief, built at the Canelo Project in 2006.

Bill Steen, of the Canelo Project in Canelo, Arizona, taught me natural plaster techniques in 2006, just before I moved to Silver City.  The workshop was one-week long, cost over $1,000, and included a myriad of interior and exterior applications, from building entire walls and shelves, to carved and built-up sculptural relief, to paints with pigments, mica, oils, and more.  (Check the site for more inspiration.)

In 2009, Asher Gelbart introduced me to natural plaster artist and instructor, Gavio (whose website is down now for redesign) who helped me begin a big project I’d long desired but needed help and inspiration to begin.

Together we built and designed two rooms, one a multi-purpose great room, with many unique and functional features, as I describe below.

Gavio returned to New Mexico this afternoon, in part to help me finish my home’s interior
– and we want to offer the opportunity for others to learn this wonderful craft.

Commercial natural plaster mixes can be purchased for nearly $100 per bag – which may not cover a single wall, even thinly.  And printed instructions for applying a simple flat coating are on the bag, but hands-on instruction is invaluable, especially if you want to have some fun.

So, as a truly natural, low-cost, and local-materials alternative, we will teach a few participants how to create, not a bag or batch, but a ton of plaster for around $100.

We’ll work approximately three days each week for the next month, depending on our energies and that of the people who’d like to participate.

We’ll mix plasters, learn how to prepare foundations for flat work and sculptures, create paints (alises), work with earth pigments, create textures, and more.

Participants will be selected according to their letters of interest.  We’re looking for people who not only want to learn, but who might have related experience.

The workshop costs $100, and participants will be offered two days of instruction, mostly by hands-on work, with more days of hands-on instruction offered no cost to those who prove their interest and capability.

Folks can pay by cash or check, and if you want to use a credit card, I can even accept credit cards.  We will also consider partial scholarships to those who give us compelling reason.

Class size will be limited to four participants per day, so please let us know soon of your interest, by calling 575-534-0123.
