For details to draw the flask, follow this online flask drawing tutorial http://vforvectors.com/create-a-chemistry-flask-illustration/
Practice 1: path, fill and stroke
Practice 2: create shapes – Pathfinder, Shape builder
Draw a flask¶
Draw order: back, top, liquid and bubble, front and hightlights, top highlights
flask back shape: draw a couple of shapes and merge them into a basic flask shape. Name the shape “Back” in layer panel. Techniques used: Object -> Path -> Average, pathfinder unite, or shape builder merge.
flask top ring shape: draw two ellipsoid, select both, also select “Back” shape, use shape builder to create a flask top ring shape, name it “Top”. Also update shape “Back”.
liquid inside: draw shape “liquid”, “liquid-top”, “liquid-top-ring”, “liquid-bottom-ring”. Used techniques: path finder intersect, direct select anchor points, gradient fill.
Create bubble with transformed fill, copy and resize twice, name the three shapes “bubble-8px”, “bubble-7px”, “bubble-5px”. Multiply and scatter arround on top of the “liquid” area. Used techniques: effect -> distort & transform -> transform. To multiply bubbles, you can use object -> transform -> transform each, and object -> transform -> transform again.
flask front and hightlights: copy “Back”, name it “Front” and bring to front, fill with highlight gradient fill. Create different hightlight areas using offset path, pathfinder or shape builder, fill them with same gradient fill. Create one thick and one thin outer stroke, both align inside. other techniques used: effect -> blur -> gaussian blur.
flask top highlights: Select “Top”, create different hightlight areas using pathfinder minus front, fill them with highlight gradient fill.
