30 ml spherical essence glass bottles

The manufacturing process illustrated produces two parts: an aluminum piece and a glass bottle body.

The aluminum part, likely a bottle cap or base, undergoes an anodizing treatment to achieve a silver finish. The anodizing process involves placing the aluminum piece in an electrolytic bath and passing an electric current through it, forming a thin oxide layer on the surface. Dyes added to the electrolyte color the oxide layer, giving it the silver appearance in this case. The resulting silver anodized finish offers an attractive and durable color for the part.

The glass bottle body is subjected to two surface treatments. First, a matte solid pink coating is applied to the glass, likely through spray coating. A matte finish helps reduce reflectivity, and the solid pink dye provides an even, uniform color across the entire bottle body.

Next, a single color white silkscreen print is added to the glass bottle. Silkscreen printing involves blocking out areas of a stencil where ink is not wanted, allowing ink to pass through just the open areas of the stencil onto the glass surface. The white print likely contains branding information, product details or other graphics to identify the bottle.

In summary, the combination of silver anodized aluminum and matte solid pink, printed glass demonstrates a subdued yet visually pleasing use of contrasting finishes and materials to produce a simple but functional consumer product. The matte coating and uniform color on the glass, along with the uniform silver finish on the aluminum part, give the bottle a clean, uncomplicated and aesthetically pleasing look suitable for many applications.
