I have gone most of this year with very few art supplies. There were numerous problems, but basically the art order I had made this year got mixed up and I ended up either getting the wrong supplies, or not getting what I ordered at all. After calling the company, I found out that it wasn't their fault, it was a mixup in the county's ordering system. Anyway, to make a long story short, I ran out of drawing paper half way through the year, and am running extremely low on paints, glue, and pastels. This means I have been begging for art supplies from everyone. I have asked classroom teachers to send me any art supplies they are not using. As a result, I have been given an interesting assortment of supplies.
One of the things that was generously donated was several gallons of washable tempera paint. Until recently, I had not used washable tempera in my art class. I have always used Sax Versa Temp for my classroom. I had not realized how spoiled I was. Washable tempera is nothing like Versa Temp. It is watered down, and sometimes dries transparent. Students have to paint 2-3 coats to make their painting look nice. I have been racking my brain for ways to make the washable tempera better. Does any know of an additive that can be added to tempera paint to make it thicker? I know that their are many acrylic mediums out there to change the consistency of acrylic paint, but I have never seen anything for tempera. I would love to hear any suggestions.
