In teenstelling met glasuur bevat glip pottebakkersklei.

In teenstelling met means in contrast to or as opposed to.

It is a fixed expression:

• in = in
• teenstelling = contrast / opposition
• met = with / to

So In teenstelling met glasuur ... means In contrast to glaze ...

It is commonly used to compare two things:

• In teenstelling met hout, brand staal nie.
  In contrast to wood, steel does not burn.

Afrikaans often puts a contrast phrase or time/place phrase at the beginning of the sentence for emphasis, just like English can.

Here, the speaker wants to highlight the comparison first:

• In teenstelling met glasuur bevat glip pottebakkersklei.

This is very natural Afrikaans. It sets up the contrast before giving the main statement.

This is because Afrikaans is a verb-second language in main clauses.

When a different element comes first—here, In teenstelling met glasuur—the finite verb must come second:

• In teenstelling met glasuur
  • bevat
    • glip
      • pottebakkersklei

If you put the subject first, you would get:

• Glip bevat pottebakkersklei.

That is also correct, but it has a more neutral word order.
Once the comparison phrase is moved to the front, the verb moves ahead of the subject:

• In teenstelling met glasuur bevat glip pottebakkersklei.

Bevat means contains.

It is the present-tense form of bevat:

• ek bevat is not normally used much
• dit bevat = it contains
• glip bevat pottebakkersklei = slip contains potter’s clay

It is related in meaning to English contain, though not related in form.

Yes—this can be confusing.

In everyday Afrikaans, glip is commonly known as a verb meaning to slip:

• Ek het op die nat vloer geglip.
  I slipped on the wet floor.

But in a pottery context, glip is a noun meaning slip—the liquid clay mixture used in ceramics.

So in this sentence, glip is not a verb. It is the subject noun:

• glip bevat ... = slip contains ...

The context makes the meaning clear.

Glasuur means glaze, especially in ceramics.

It can also be used in other contexts, such as icing or glazing, depending on the situation, but here it clearly refers to pottery glaze because of the words glip and pottebakkersklei.

Pottebakkersklei means potter’s clay or pottery clay.

It is a compound noun:

• pottebakker = potter
• klei = clay

So:

• pottebakkersklei = potter’s clay

Afrikaans, like Dutch and German, often combines words into one long compound noun instead of writing them separately.

Because Afrikaans normally writes compound nouns as a single word.

So instead of writing something like potter’s clay as separate words, Afrikaans usually combines them:

• pottebakker
  • klei → pottebakkersklei

This is very common:

• tafeldoek = tablecloth
• skoolboek = schoolbook
• motorhuis = garage

If you are an English speaker, this is something to get used to, because English often leaves these as two words, while Afrikaans usually joins them.

Afrikaans often leaves out the indefinite article in general statements, especially when talking about substances or materials.

Here the sentence is talking about glaze, slip, and potter’s clay as materials in general, not about one specific item:

• glasuur
• glip
• pottebakkersklei

That is similar to English when we say:

• Water contains oxygen.
• Steel contains carbon.

We do not usually say a water or a steel in those general material senses.

Yes. That is a correct and simpler version.

• Glip bevat pottebakkersklei.
  Slip contains potter’s clay.

The original sentence adds the comparison:

• In teenstelling met glasuur bevat glip pottebakkersklei.

So the difference is not grammar correctness, but emphasis and meaning:

• Glip bevat pottebakkersklei. = plain statement
• In teenstelling met glasuur bevat glip pottebakkersklei. = statement with contrast

Yes, it is the same word met, but in this fixed phrase it is best understood as part of the whole expression.

On its own:

• met usually means with

But in in teenstelling met, the full phrase means:

• in contrast to
• as opposed to

So learners should memorize in teenstelling met as one unit rather than translating each word too literally.

A rough pronunciation guide is:

In teenstelling met glasuur bevat glip pottebakkersklei.
in TEEN-stel-ling met khla-SYUR be-FAT ghlip POH-tuh-bah-kers-klay

A few notes:

• g in Afrikaans is usually a strong throaty sound, not an English g
• ui in glasuur can be tricky for English speakers
• klei sounds roughly like clay

Pronunciation varies by speaker and region, but this approximation is enough to get started.

Yes. It sounds like an informative or technical sentence, especially in a ceramics context.

The structure is concise and factual:

• contrast one material with another
• state what one of them contains

So it would fit well in:

• a textbook
• a pottery guide
• technical writing about ceramics

The biggest grammar lesson here is verb-second word order in Afrikaans main clauses.

Compare:

• Glip bevat pottebakkersklei.
  Subject first, so the verb comes second.

• In teenstelling met glasuur bevat glip pottebakkersklei.
  The contrast phrase comes first, so the verb still comes second, and the subject moves after it.

That pattern is extremely important in Afrikaans:

• Vandag lees ek.
• By die huis werk hy.
• In die somer swem ons baie.

So this sentence is a very good example of that core rule.
