One day at work I had some leftover epoxy tooling compound after casting a master for the stepping stones. Not wanting to waste it, I poured it into the plastic moulds that were used to cast the concrete salt cellars. Those moulds were made to create half-spheres, but I was using them backwards to make […]
Salt Cellars produced for the salt show at Fouladi Projects on Market in San Francisco. The concrete is cast in a plastic form and the wood lids are turned on the lathe. There are three sizes of concrete, the medium and larger cellars have lids. Scoops carved from Eucalyptus bark.
Seeing pictures of ancient dice inspired me to make them out of concrete. Throughout history dice were probably carved from stone, maybe wood, but for sure bone. Here is a nice link showing how to make these old dice out of antler. Last week I had a reason to make a small rubber test mould […]
Demold Rubber: After about 12+ hours, the rubber mould has cured. First remove the form walls and then gently pry up on the rubber with a plastic putty knife. The rubber should pull off easily with almost no damage to the original plasticine piece. The rubber picks up EVERY detail from the original piece, which […]
Yesterday I spent some time turning wood lids for the concrete salt cellars I’ve been working on. Woodworkers call this wood Claro Walnut (Juglans Hindsii), but it’s also known as Northern California Walnut because it grows around these parts. Unfortunately it’s seriously endangered, so either don’t use it, or use it while you still can, […]
Here’s what I’ve been doing at work recently. In the past we created a series of stepping stone moulds for casting concrete, one of which can be seen here. Last time I made a computer file and the shape was cut out on a CNC router, which is great, but the shapes were very controlled, […]
I made these concrete egg holders for the 21pop shop at the FOG art and design fair 2014 in san francisco. In order to produce a lot of the same thing in a short amount of time, I made a few rubber molds and used a concrete mix that sets up very quickly (rapidset). This […]
