Galalith Buttons Value Guide

Galalith buttons are highly prized by collectors for their unique origin as a 'milk stone' plastic made from casein and formaldehyde. Originating from Germany, these 1920-1940 era fasteners are celebrated for their ability to mimic expensive natural materials like horn and tortoise shell.

What affects the value of Galalith Buttons?

• Color rarity, with vibrant dyes or complex amber and brown swirls commanding higher prices.
• The complexity of the carving or the presence of geometric Art Deco patterns.
• Overall physical condition, specifically the absence of deep cracks or warping from moisture exposure.
• Size and quantity, as larger coat buttons or complete original sets are more valuable to restorers.

How to Identify Galalith Buttons?

• Look for a high-gloss finish and deep, saturated colors that do not fade like other early plastics.
• Check for a lack of molding seams, as Galalith was typically machined or carved from sheets and rods.
• Perform a 'hot water test' to detect a faint odor of sour milk, which is characteristic of casein-based materials.
• Examine the surface for fine crazing or surface cracks, which often occur as the material ages and dehydrates.

History of Galalith Buttons

Galalith, derived from the Greek 'gala' for milk and 'lithos' for stone, is an early plastic material invented in 1897 by a German chemist. It was made from casein, a milk protein, and formaldehyde. Galalith was popular in the early to mid-20th century for buttons, buckles, and jewelry due to its ability to be dyed in vibrant colors and mimic natural materials like horn and tortoise shell. Its use declined with the advent of cheaper, petroleum-based plastics.
