Types Of Materials from Which Advertising Signs Were Made
Advertising signs for gas stations had to be made of durable materials that could withstand all weather conditions. That’s why different sign-making techniques have been developed, which you can learn about at old gas stations signs.
The first advertising signs began to be made of porcelain. This is a very durable material, and many craftsmen from Europe have contributed to their development. From Europe, these signs were imported to America and became one of the main decorations of many gas stations. With their vivid colors and strong construction, they could stand for years and attract the attention of drivers.

Porcelain inscriptions were created by mixing powdered glass with clay, after which they were fired in furnaces at high temperatures. This process allowed them to be completely resistant to corrosion, as well as not being able to fade in the sun, making them ideal for gas station advertisements.
Today, these signs are very rare and therefore in high demand among many collectors.
Apart from porcelain signs, metal signs were also made. Sheet metal or steel was used for them. Each of these signs were hand painted, so this made them quite expensive.
A little later, baked enamel signs appeared, which were made of metal and enamel paint. The final treatment was baking in large ovens, which gave them a perfect shine. Because they were resistant to all weather conditions, they became ideal for advertising at gas stations.
